Description

The present invention relates to an infectious organism removal and contaminated breeding water real-time disinfection system for aquatic organism infectious disease prevention measures, which separates infectious disease-infected aquaculture objects and their dead bodies (hereinafter collectively referred to as infectious organisms) from breeding water at aquaculture farms where an aquatic organism infectious disease has occurred, sterilizes and disinfects the pathogen-contaminated breeding water, and then discharges it outside the aquaculture farm.

Generally, in land-based indoor farms or outdoor farms on land, including embankment (levee) farms along coastlines, a large number of farmed organisms are raised in a limited area at high density. Therefore, even if a few individuals become infected with an infectious disease, the disease can quickly spread to all individuals in the tank, resulting in mass mortality of the farmed organisms. A typical example is acute hepatopancreatic necrosis disease (AHPND), in which Vibrio bacteria carrying a specific toxin gene attack the hepatopancreas of shrimp.

AHPND is an infectious disease that causes significant damage to the shrimp farming industry worldwide, with annual damage estimated at approximately $5 billion. There are approximately 600 shrimp farms in Korea, with double-bank farms accounting for over 80% of them. Recently, at an embankment farm in Sinan County, South Jeolla Province, approximately 70% of the farmed shrimp died due to AHPND infection, resulting in damage of approximately 12 tons and damage worth approximately 200 million won.

Including the aforementioned AHPND, the Aquatic Organism Disease Control Act designates a total of 26 aquatic organism infectious diseases as statutory infectious diseases subject to quarantine measures in Korea, and these measures are being implemented accordingly. However, current quarantine measures only stipulate the culling, isolation, and movement restrictions of aquatic organisms infected with infectious diseases, as well as the disinfection of equipment and objects contaminated in the process. As a result, there are insufficient regulations, methods, and detailed guidelines for sterilizing and disinfecting breeding water contaminated with pathogens along with infectious organisms, and safely discharging it outside the aquaculture facility.

In the case of the present applicant, we have previously filed and received patent registration (Patent Application No. 10-1728426) for a treatment system that prevents the spread of various diseases and contagious illnesses and environmental pollution caused by infectious organisms by quickly, low-cost, and highly efficient treatment of infectious organisms collected from aquaculture farms, etc., in line with current quarantine measures. We also go beyond simple treatment concepts such as landfilling or incineration of infected organisms and recycle the infected organisms as high-quality organic fertilizer.

However, the technical features of the above-mentioned prior application focused on immediately treating infectious organisms that occur in fish cage farms and other facilities at sea, making it somewhat unsuitable for application to land-based farms. Furthermore, the actual treatment targets were limited to infectious organisms in line with current quarantine measures, meaning that it could not be used to treat breeding water stored in aquaculture tanks that is contaminated with pathogens along with infectious organisms.

Due to the above-mentioned factors, land-based aquaculture farms have only been able to collect infected organisms and either landfill or incinerate them, or turn them into fertilizer using treatment systems such as those previously filed by the applicant. However, water contaminated with pathogens and stored in aquaculture tanks is often released without further treatment, and even then, the treatment methods used have been limited to a simple method of directly pouring large amounts of disinfectant into the aquaculture tanks.

However, if pathogen-contaminated breeding water is released without permission, there is a very high risk of the disease spreading to the various aquatic organisms living in nearby rivers and coastal waters. Furthermore, the method of directly adding large amounts of disinfectant to the breeding water requires considerable processing time and costs (the cost of culling AHPND-infected shrimp at the Sinan County aquaculture facility and disinfecting the breeding water: over 30 million won), and not only does it have very low actual processing efficiency, but it also poses the problem of the disinfectant components contained in the breeding water flowing into nearby rivers and coastal waters, causing secondary environmental pollution.

To solve the above-mentioned conventional problems, a treatment system must be provided that can collect and dispose of infectious disease-infected organisms in land-based aquaculture tanks by burying, incinerating, or fertilizing them, and can also sterilize and disinfect the breeding water contaminated with pathogens stored in the aquaculture tanks to an environmentally harmless level before safely discharging it outside the aquaculture farm. This system can be installed directly at land-based aquaculture farms, or it can be implemented as a mobile quarantine system that can be deployed at land-based aquaculture farms as needed.

The present invention has been made to meet the above-mentioned requirements, and is a sprut pump and a fish pump. The system uses a main transfer pump, such as a suction pump, to suck and transfer the culture water stored in the aquaculture tank together with infectious organisms to an infectious organism separation tank, where the culture water is separated from the infectious organisms. The culture water is then supplied to a pre-treatment filter and/or skimmer to remove various foreign substances from the culture water, and then supplied to a sterilization device using an ultraviolet lamp, ozone lamp, plasma generator, or electrolysis method to completely remove even pathogens from the culture water. This allows the contaminated culture water stored in the aquaculture tank to be purified and sterilized in a quick, efficient, and economical manner and safely discharged outside the aquaculture facility. This fundamentally prevents the recurrence and spread of aquatic infectious diseases caused by the unauthorized discharge of contaminated culture water, and also prevents unnecessary waste of treatment time and costs due to the direct injection of large amounts of sterilizing and disinfecting agents into the aquaculture tank, as well as secondary environmental pollution caused by the components of the sterilizing agents. The system's main technical objective is to provide an infectious organism removal and real-time disinfection system for aquatic infectious disease prevention measures.

In addition, the present invention applies a water treatment device using a plasma generator as the sterilization device. Excess ozone gas accumulated inside the sterilization device is supplied to a skimmer so that the ozone gas generates bubbles to capture and remove foreign matter. Meanwhile, the breeding water discharged from the sterilization device containing residual ozone gas is temporarily retained in a drainage tank of a specified capacity equipped with an ozone filter exhaust pipe before finally being discharged to the outside. This allows a certain level of pathogen treatment with ozone gas to be performed in parallel in the skimmers and drainage tanks before and after the sterilization device, and the sterilization device can be operated Another technical objective is to further maximize the purification of the base breeding water and the sterilization and disinfection functions of pathogens while minimizing the ozone gas concentration in the final discharged breeding water. By connecting an aspirator equipped with a height-adjustable dustpan-type suction duct and a scale bar for measuring water level to a receiving plate placed on the bottom of the aquaculture tank to the main transfer pump, the simultaneous transfer of breeding water and infectious organisms via the main transfer pump can be carried out more efficiently without clogging the transfer pipes, in accordance with the condition of the bottom of the aquaculture tank and the level of the stored breeding water.

The infectious organism separation tank is made up of the introduction tank for the breeding water and infected organisms via the main transfer pump, the infectious organism recovery tank on one side, and the breeding water storage tank on the lower side. A zigzag guide tray, which is inclined upwards and downwards using a perforated plate, is placed inside the introduction tank, with the final outlet of the guide tray protruding toward the recovery tank. A colander-type recovery tray that can be inserted and removed is placed inside the recovery tank. This makes it easier and more systematic to separate the breeding water from the infected organisms and to collect (recover) the infected organisms, without the infectious organisms excessively gathering and accumulating at the outlet of the recovery tank. Additional technical objectives include installing an overflow pipe above the storage tank of the infectious organism separation tank to automatically drain excess breeding water into the aquaculture tank, and installing a scum collection tube on the outside of the skimmer to prevent unnecessary leakage of untreated contaminated breeding water and floating debris. By using a drum filter with excellent solid removal capabilities together with the skimmer as a pre-treatment filter, various foreign substances in the breeding water fed into the sterilization device can be more completely removed, minimizing breakdowns or malfunctions of the sterilization device and maximizing its inherent functionality and service life.

As a means for solving the above technical problems, the infectious organism removal and contaminated breeding water real-time disinfection system for aquatic organism infectious disease prevention measures according to the present invention comprises a main transfer pump that sucks and transfers breeding water stored in an aquaculture tank together with infectious organisms through a transfer pipe, an infectious organism separation tank that separates and stores the breeding water supplied through the transfer pipe of the main transfer pump from the infectious organisms, a pre-treatment mechanism that removes foreign matter from the breeding water supplied through the infectious organism separation tank, and a sterilization and disinfection device that sterilizes and disinfects the breeding water supplied through the pre-treatment mechanism, wherein the main transfer pump is a spur pump or a fish pump. The pre-treatment mechanism is a pre-treatment filter for removing solids from the breeding water and a skimmer for trapping and removing proteins and harmful gas components in the breeding water as bubbles, or both the pre-treatment filter and the skimmer are used. The sterilization and disinfection device is a water treatment device using an ultraviolet lamp, an ozone lamp, a plasma generator, or an electrolysis method. The sterilization and disinfection device is a water treatment device using a plasma generator, and an injection tube for excess ozone gas extends from the sterilization and disinfection device and is connected to the skimmer to create bubbles using the ozone gas. The disinfection system further includes a drain tank for temporarily storing the breeding water discharged containing ozone gas. A drain pipe with a drain valve is connected to the bottom of the drain tank, and an exhaust pipe equipped with an ozone gas neutralizing filter is connected to the top of the drain tank.

The disinfection system according to the present invention further includes an aspirator connected to the main transfer pump and inserted into the aquaculture tank. The aspirator comprises at least two support stands vertically connected to a receiving plate placed on the bottom of the aquaculture tank, a dustpan-shaped suction duct connected to each of the support stands and located on the top of the receiving plate, and a connecting pipe connected to the rear side of the suction duct and assembled to the transfer pipe of the main transfer pump. Each of the support stands is a height-adjustable stand with mounting holes drilled at regular intervals along the height direction, and the suction duct is detachably assembled to each height-adjustable stand so that its height from the receiving plate can be adjusted. A scale bar of a predetermined length is vertically connected to the receiving plate of the aspirator so that the water level of the culture water stored in the aquaculture tank can be measured, and the surface of the scale bar is provided with scales at regular intervals.

The infectious organism separation tank also includes an introduction tank connected to a transfer pipe extending from a main transfer pump and into which infectious organisms are introduced along with the breeding water; a recovery tank located on one side of the introduction tank for collecting the infectious organisms; and a storage tank located below the introduction tank and the recovery tank for storing the breeding water separated from the infectious organisms. The introduction tank is installed so as to have a bottom opening communicating with the storage tank, an outlet for infectious organisms provided in the wall on the recovery tank side, and a sealed top surface. A guide tray serving as a partition-type perforated plate is installed inside the introduction tank to guide the infectious organisms to the outlet on the recovery tank side. The recovery tank is installed so as to communicate with the storage tank via a perforated partition-type bottom surface with its top surface open. A supply pipe is connected to the lower part of the storage tank for supplying the breeding water separated from the infectious organisms to a pretreatment mechanism. The transfer pipe is connected to the upper end of the front wall of the introduction tank, and the outlet for the infectious organisms on the recovery tank side is provided at the center of the rear wall of the introduction tank, while the recovery tank is disposed at the rear of the introduction tank to have a height corresponding to the outlet for the infectious organisms. The guide tray includes a main tray installed at a downward incline from the inner surface of the front wall of the introduction tank, which corresponds to the lower part of the transfer pipe, toward the infectious organism outlet, and an auxiliary tray installed at a downward incline from the inner surface of the rear wall of the introduction tank, which corresponds to the upper part of the infectious organism outlet, to the upper center of the main tray. The main tray and auxiliary tray are provided with side walls of a predetermined height on the left and right sides of a partition-type perforated plate, and the lower end of the main tray protrudes a predetermined length toward the recovery tank after passing through the outlet for infectious organisms in the lower wall.

Additionally, a colander-type collection tray for storing infectious organisms and discharging water is inserted inside the collection tank, and a storage opening is formed in one side wall of the collection tank for lateral insertion and removal of the collection tray. An overflow pipe is connected to the upper part of the storage tank for discharging excess rearing water stored separately from infectious organisms into the aquaculture tank, and the capacity of the rearing water discharged through the overflow pipe is at least 1.5 times the capacity of the rearing water discharged through the supply pipe at the bottom of the storage tank. The pre-treatment filter is a cylindrical filtration filter rotatable around an axis inside a filter casing. The drum filter is inserted into the tank and has a cleaning water injection pipe installed inside the filter casing corresponding to the upper side of the filter. The breeding water supplied to the drum filter from the storage tank of the infectious organism separation tank is first poured into the internal space of the filter, and then passes through the filter to be stored inside the filter casing, which is then supplied to the skimmer or sterilization device. A scum collection tube is installed outside the skimmer, and scum is captured in air bubbles and discharged to the outside through the upper end of the skimmer. A pipe with a drain valve is connected to the bottom of the collection tube.

The sterilization and disinfection device also includes a reaction tank for storing breeding water supplied through a pretreatment mechanism, an apparatus casing installed on top of the cover plate of the reaction tank, a control unit installed inside the apparatus casing, and a plasma generator connected to the control unit and extending through the cover plate of the reaction tank to the lower interior of the reaction tank. A supply pipe for breeding water that has passed through the pretreatment mechanism is connected to one side of the reaction tank, while a supply pipe for discharging breeding water that has been sterilized and disinfected by the plasma generator is connected to the other side of the reaction tank. The injection tube is connected to the upper end of the reaction tank. The plasma generator is connected to the skimmer side and extends to the skimmer side. The plasma generator has a discharge electrode and a ground electrode installed inside and outside the dielectric tube, respectively, and a reaction space for generating ozone gas is provided between the dielectric tube and the discharge electrode. The discharge electrode and ground electrode are connected to a control unit via an insulating cap provided on the top of the cover plate of the reaction vessel. An air pump is installed inside or outside the device casing, and an air injection pipe extending from the air pump is installed so as to communicate with the reaction space between the dielectric tube and the discharge electrode via the insulating cap of the plasma generator.

According to the present invention described above, breeding water stored in an aquaculture tank in a state contaminated with pathogens along with infectious organisms infected with an infectious disease is sucked and transferred to the main transfer pump along with the infectious organisms, and then temporarily separated and stored in an infectious organism separation tank. The breeding water is then supplied to a pre-treatment filter and/or skimmer to remove various foreign substances from the breeding water, and then supplied to a sterilization device using an ultraviolet lamp, ozone lamp, plasma generator, electrolysis method, etc., thereby achieving the effect of completely removing even pathogens from the breeding water.

This allows contaminated breeding water stored in aquaculture tanks to be purified and sterilized in a faster, more efficient, and more economical manner, allowing it to be safely discharged outside the aquaculture farm. Meanwhile, the infectious organisms separated from the breeding water in the infectious organism separation tank can be collected (recovered) separately and landfilled, incinerated, or converted into fertilizer. This fundamentally prevents the recurrence and spread of aquatic infectious diseases caused by the unauthorized discharge of pathogen-contaminated breeding water, and also prevents unnecessary waste of processing time and costs due to the direct injection of large amounts of sterilizing and disinfecting agents into the aquaculture tanks, as well as secondary environmental pollution caused by the components of the sterilizing and disinfecting agents.

In particular, when using a plasma generator-based sterilization device, excess ozone gas is supplied to the skimmer to create bubbles that capture foreign matter. The breeding water discharged from the sterilization device containing residual ozone gas is temporarily retained in a drainage tank equipped with an ozone filter exhaust pipe before being finally discharged to the outside. This allows a certain level of pathogen treatment with ozone gas to be performed in parallel in the skimmers and drainage tank before and after the sterilization device, further maximizing the sterilization device's functions of purifying the breeding water and sterilizing pathogens, while also minimizing the ozone gas concentration in the breeding water finally discharged.

In addition, when an aspirator of the above-described structure is used in conjunction with a main transfer pump, the simultaneous transfer of culture water and infected organisms by the main transfer pump can be performed more efficiently in accordance with the bottom condition of the aquaculture tank and the level of the culture water, without clogging the transfer pipes. When an infectious organism separation tank of the above-described structure is used, the separation of culture water and infected organisms and the collection (recovery) of infected organisms can be performed more easily, systematically, and reliably, without the infectious organisms excessively concentrating and accumulating at the outlet.

Additionally, the overflow pipe installed in the storage tank of the infectious organism separation tank and the scum collection tube installed outside the skimmer prevent the unnecessary leakage of untreated contaminated breeding water and floating debris. By using a drum filter with excellent solid removal capabilities together with the skimmer as a pre-treatment filter, various foreign substances in the breeding water fed into the sterilization device are more completely removed, minimizing breakdowns and malfunctions of the sterilization device and maximizing its inherent functionality and service life, among other extremely useful effects.

The present invention will now be described in detail with reference to the accompanying drawings.

As shown in Figure 1, the infectious organism removal and contaminated breeding water real-time disinfection system for aquatic organism infectious disease prevention measures of the present invention is composed primarily of a main transfer pump 3 that sucks and transfers the breeding water stored in the aquaculture tank 2 together with the infectious organisms through a transfer pipe 4, an infectious organism separation tank 20 that separates the breeding water supplied via the transfer pipe 4 of the main transfer pump 3 from the infectious organisms and stores it, a pretreatment mechanism that removes various foreign substances from the breeding water supplied via the infectious organism separation tank 20, and a sterilization and disinfection device 50 that sterilizes and disinfects the breeding water supplied via the pretreatment mechanism.

The main transfer pump 3 can be any type of pump mechanism capable of sucking in and transporting infected organisms along with the breeding water without clogging. It is installed so that its position can be adjusted using a caster-equipped carrier 3a in the drawing. Typical examples include the well-known sprut pump and fish pump. A sprut pump is a centrifugal pump with spiral vanes on the impeller, and is used to discharge sludge or solids along with wastewater. A fish pump uses negative pressure (pressure below atmospheric pressure) generated by spraying breeding water at high pressure (high speed) from the first suction pipe through a jet nozzle to suck in fish into the second suction pipe, where they are then transported along with the breeding water.

Representative examples of the pre-treatment mechanism include a pre-treatment filter 30 for removing solids from the breeding water and a skimmer 40 for capturing and removing proteins and harmful gas components in the breeding water as bubbles. While either the pre-treatment filter 30 or the skimmer 40 can be selected depending on the amount and type of foreign matter contained in the breeding water, it is preferable to use both the pre-treatment filter 30 and the skimmer 40 whenever possible. The pre-treatment filter 30 may be any known type of water treatment filter. Since a wide variety of skimmers 40 are known technologies used in the water treatment field, only a representative example applicable to the present invention will be briefly mentioned below.

In addition, the sterilization and disinfection device 50, which is responsible for the core water treatment in this invention, can be selected from existing water treatment devices that use ultraviolet lamps, ozone lamps, or plasma generators, or that use electrolysis. However, when considering all factors, such as the sterilization and disinfection performance of the breeding water, the treatment time, and the space (volume) and load required to install the device, a sterilization and disinfection device 50 using a plasma generator is considered to be the most reasonable. However, it should be made clear at the outset that any type of water treatment device can be used as the sterilization and disinfection device 50 as long as it can safely sterilize and disinfect pathogens contained in the breeding water at a high level.

More specifically, to enable the simultaneous suction and transfer of the breeding water and infectious organisms using the main transfer pump 3 to be carried out more efficiently in accordance with the state of the bottom of the aquaculture tank 2 and the level of the breeding water, an aspirator 10 connected to the main transfer pump 3 is further installed inside the aquaculture tank 2, and the infectious organism separation tank 20 is equipped with an overflow pipe 7 that automatically discharges only the excess amount into the aquaculture tank 2 when the amount of breeding water stored separately from the infectious organisms exceeds the treatment standard value, thereby preventing unnecessary leakage of untreated contaminated breeding water to the outside.

In addition, when using the sterilization and disinfection device 50 using the plasma generator, excess ozone gas accumulated inside the sterilization and disinfection device 50 is supplied to the skimmer 40 via the injection tube 8, allowing the ozone gas to create bubbles for capturing foreign matter. Meanwhile, the breeding water discharged from the sterilization and disinfection device 50 containing residual ozone gas is temporarily retained in the drainage tank 60 before being finally discharged to the outside, thereby enabling a certain level of sterilization and disinfection of pathogens by ozone gas to occur in parallel in the skimmer 40 and drainage tank 60 before and after the sterilization and disinfection device 50.

Figure 1 shows a typical example in which the disinfection treatment system 1 of the present invention is fixedly installed at an aquaculture farm with tables 9 for each device. However, the entire system from the aspirator 10 to the wastewater tank 60 can also be integrated into a vehicle such as a truck and used as a mobile quarantine system. Each device from the infectious organism separation tank 20 to the wastewater tank 60 is connected in sequence by a rearing water supply pipe 5. However, it is preferable to install a supply pump 6 in parts where it is difficult to use a head-down supply using the stored water level of the rearing water, such as the supply pipe 5 connecting the pre-treatment filter 30 and skimmer 40, and the supply pipe 5 connecting the skimmer 40 and sterilization/disinfection device 50.

Figures 2 to 11 show in more detail each of the devices essentially used in the present invention, from the suction device 10 to the wastewater tank 60. The suction device 10, which is inserted into the aquaculture tank 2 while connected to the main transfer pump 3, is composed of at least two support stands vertically connected to a receiving plate 15 placed on the bottom of the aquaculture tank 2, as shown in Figures 2 and 3, a dustpan-shaped suction duct 11 connected to each of the support stands and placed on top of the receiving plate 15, and a connecting pipe 12 connected to the rear side of the suction duct 11 and assembled with the transfer pipe 4 of the main transfer pump 3.

As described above, the dustpan-shaped suction duct 11 connected to the transfer pipe 4 of the main transfer pump 3 is separated from the bottom of the aquaculture tank 2 by a fixed distance (height) using the backing plate 15 and support base. This prevents foreign matter such as feed waste, excrement, and sludge that has settled in large quantities at the bottom of the aquaculture tank 2 from being sucked in all at once through the transfer pipe 4 along with the infectious organisms. Instead, they are mixed with the aquaculture water at an appropriate rate by taking advantage of the suction force of the aquaculture water through the suction duct 11. This prevents the transfer pipe 4 from becoming clogged with foreign matter and infectious organisms at the bottom of the aquaculture tank 2, and allows the treatment load from the infectious organism separation tank 20 to be maintained at an appropriate level.

More preferably, mounting holes 14 are drilled at regular intervals along the height direction of the support stand, and each support stand is installed as a height adjustment stand 13 for the intake duct 11. Assembly holes (not shown) corresponding to the mounting holes 14 of the height adjustment stand 13 are also formed on the body of the intake duct 11, allowing the intake duct 11 to be detachably assembled to each height adjustment stand 13 using assembly means such as bolts so that the height from the receiving plate 15 can be adjusted. A scale bar 17 of a predetermined length, with graduations 18 formed at regular intervals, is attached vertically to the receiving plate 15 together with the height adjustment stand 13 so that the water level of the aquaculture water stored in the aquaculture tank 2 can be grasped.

By applying the above-described method, the position of the intake duct 11 can be easily adjusted to the most suitable position for transferring the culture water and infectious organisms based on the amount of foreign matter accumulated at the bottom of the aquaculture tank 2, the condition of the bottom, and the water level of the culture water stored in the aquaculture tank 2. Furthermore, the amount of culture water supplied via the main transfer pump 3 can be checked in real time using the scale bar 17, enabling a fixed-volume supply treatment cycle of the culture water to match the treatment capacity of the disinfection treatment system 1 according to the present invention, thereby making the simultaneous transfer of the culture water and infectious organisms even more efficient.

In the drawing, the support plate 15 is separated into two, left and right, and the scale bar 17 is installed on the support plate 15 together with the height adjustment base 13 so that it functions as a support base for the intake duct 11 in parallel. Two height adjustment bases 13 are installed on one support plate 15 and one on the other, symmetrically installed together with the scale bar 17. The left and right support plates 15, height adjustment bases 13, and scale bar 17 are connected and fixed together by a pair of angle frame-type reinforcing bases 16. The connecting pipe 12 is provided with a pipe connection portion 19 equipped with a flange portion for piping connection to the transfer pipe 4, but such additional structure can be freely changed as needed.

Shown in Figures 4 and 5 is an infectious organism separation tank 20 used in the present invention, which is connected to a transfer pipe 4 extending from a main transfer pump 3 and is composed of an introduction tank 21 into which infectious organisms are introduced along with the rearing water, a recovery tank 22 located on one side of the introduction tank 21 (the right side in the drawing) for collecting the infectious organisms, and a storage tank 23 located below the introduction tank 21 and the recovery tank 22 for storing the rearing water separated from the infectious organisms.

In the drawing, the introduction tank 21 is installed so as to have a bottom opening 21a that communicates with the storage tank 23, an outlet for infectious organisms provided in the wall on the recovery tank 22 side, and a sealed top surface. A guide tray 24 serving as a partition-type perforated plate 25 that guides infectious organisms to the outlet on the recovery tank 22 side is installed inside the introduction tank 21. The recovery tank 22 is installed so as to communicate with the storage tank 23 via its bottom surface in the form of a perforated partition plate 28 with its top surface open. A supply pipe 5 is connected to the lower part of the storage tank 23, supplying rearing water separated from infectious organisms to the pre-treatment mechanism, and the aforementioned overflow pipe 7 is connected to the upper part of the storage tank 23.

More specifically, the transfer pipe 4 is connected to the upper end of the front wall of the introduction tank 21 (left side in the drawing), and the outlet for the infectious organisms on the recovery tank 22 side is provided at the center of the rear wall of the introduction tank 21 (right side in the drawing). The recovery tank 22 is positioned at the rear of the introduction tank 21 to have a height corresponding to the outlet for the infectious organisms. The guide tray 24 has a zigzag structure that slopes alternately up and down, with a main tray installed at a downward angle from the inner surface of the front wall of the introduction tank 21, which corresponds to the bottom of the transfer pipe 4, toward the outlet for the infectious organisms, and an auxiliary tray installed at a downward angle from the inner surface of the rear wall of the introduction tank 21, which corresponds to the top of the outlet for the infectious organisms, to the upper center of the main tray.

The above-mentioned guide tray 24 arrangement structure allows infectious organisms introduced into the introduction tank 21 along with the rearing water to be dispersed evenly in stages across the auxiliary tray and main tray without excessively collecting and accumulating at the outlet on the recovery tank 22 side, thereby enabling more systematic and reliable separation of the rearing water and infectious organisms. The main tray and auxiliary tray are preferably provided with side walls 26 of a predetermined height on the left and right sides of the partition-type perforated plate 25, and it is preferable that the lower end of the main tray equipped with these side walls 26 pass through the outlet for the infectious organisms and protrude a predetermined length toward the recovery tank 22.

In addition, it is preferable to insert a sieve-type collection tray 27 with drainage holes 27a inside the collection tank 22 for storing infected organisms and draining moisture. The collection tray 27 is preferably manufactured with dimensions such that its upper edge is close to or in contact with the inner surface of the collection tank 22 to prevent infected organisms from falling out of the collection tray 27. It is also preferable to form a storage opening 22a in one wall of the collection tank 22 (the right side in the drawing) that allows the collection tray 27 to be inserted and removed laterally so that infected organisms separated from the breeding water can be collected along with the collection tray 27.

In addition, it is preferable to install a spacer 28a on the upper side of the perforated partition plate 28 that forms the bottom of the collection tank 22 to separate the collection tray 27 from the perforated partition plate 28 to ensure smooth dehydration of the infectious organisms.If necessary, the spacer 28a can also be provided with the function of a digital scale (weighing scale) that can measure the weight of the infectious organisms.This allows the operation of the disinfection treatment system 1 of the present invention to be temporarily stopped when a set weight of infectious organisms is collected inside the collection tray 27, and the system can then be restarted when a collection tray 27 emptied of the infectious organisms or a new collection tray 27 is reloaded.

In the drawing, the outer frame 20a, which acts as a reinforcing angle frame, is assembled and installed vertically along the outer corners of the infectious organism separation tank 20, using the storage tank 23 as a base. Support legs 29 for the infectious organism separation tank 20 are installed at the lower end of each outer frame 20a. The overflow pipe 7 is connected to the storage tank 23 as a total of two piping lines, and the supply pipe 5 is connected to the storage tank 23 as a single piping line. This is to ensure that the volume of culture water discharged through the overflow pipe 7 is greater than the volume of culture water discharged through the supply pipe 5, preferably by a minimum of 1.5 times and a maximum of 3 times, thereby fundamentally preventing the water level in the storage tank 23 from exceeding the standard value and leaking outside the infectious organism separation tank 20.

The structure of the infectious organism separation tank 20 described above corresponds to the optimal embodiment applicable to the present invention, and it should be made clear that any structure of infectious organism separation tank 20 can be applied as long as it satisfies the conditions for separating and storing separately the rearing water supplied together with infectious organisms via the main transfer pump 3 from the infectious organisms. The simplest application example is one in which only the collection tank 22 is placed on top of the storage tank 23, and the aforementioned collection tray 27 or a landing net or four-handle net-like collection mechanism with handles can be inserted inside the collection tank 22.

Figures 6 and 7 show an example of a pretreatment filter 30 used in the present invention. This is a well-known drum filter in which a cylindrical filter 34 is rotatably inserted into a filter casing 31, which serves as a sealed tank supported by a base 32, and a cleaning water injection pipe 39 is installed inside the filter casing 31 above the filter 34. Rearing water supplied to the drum filter from the storage tank 23 of the infectious organism separation tank 20 is initially introduced into the internal space of the filter 34, and the rearing water stored inside the filter casing 31 via the filter 34 is then supplied to the skimmer 40 via a supply pipe 5 equipped with a supply pump 6.

The filtration filter 34 is attached to the outer surface of the filter frame 33, which is a cylindrical framework having a front cover 35 and a rear cover 36. A rotary support shaft 37 is installed in the center of the front cover 35 and rear cover 36, passing through the filter casing 31 with a bearing 37a interposed therebetween. The supply pipe 5 extending from the infectious organism separation tank 20 passes through the rotary support shaft 37 of the front cover 35 with a bearing 37a interposed therebetween and extends to the inside of the filter frame 33. A transmission mechanism 38a (a chain and sprocket in the drawing) connected to a drive motor 38 is installed at the end of the rotary support shaft 37 of the rear cover 36, so that the filtration filter 34 can be rotated together with the filter frame 33. Cleaning water spray nozzles 39a are installed at regular intervals on the cleaning water spray pipe 39.

The detailed configuration of the drum filter described above is also within the scope of well-known technology and widely known to those skilled in the art. The bearing 37a is preferably a waterproof bearing that can prevent leakage of the breeding water. The reason why the drum filter is used as the optimal embodiment of the pre-treatment filter 30 used in the present invention is that it has the most excellent solid removal function among various types of water treatment filters. Therefore, by using it in conjunction with the skimmer 40, it can more completely remove various foreign matter from the breeding water fed into the sterilization and disinfection device 50, thereby minimizing breakdowns and malfunctions of the sterilization and disinfection device 50 and maximizing its inherent functionality and service life.

Figure 8 shows an example of a skimmer 40 used in the present invention. A scum discharge pipe 46 and a breeding water supply pipe 5 are connected to the upper and lower ends of a cylindrical collection casing 41 of a predetermined height. A stand pipe 42 of a predetermined height is inserted into the inside of the collection casing 41 in a double-pipe configuration. A receiving tube 44 is installed at the lower end of the collection casing 41. A breeding water supply pipe 5 is connected to the lower end of the stand pipe 42, passing from the bottom plate 43 of the collection casing 41 through the receiving tube 44 and extending to the sterilization device 50 side.

Furthermore, the injection tube 8 extends from the sterilization and disinfection device 50 that uses a plasma generator, and then penetrates the lower part of the collection casing 41 in a watertight manner to a position adjacent to the standpipe 42. Instead of the injection tube 8, a known bubble generator such as an air stone may be inserted. The bubble generator is connected to an air pump (not shown) via an air injection tube. A lattice-shaped guide channel 45 is installed at the top of the inside of the collection casing 41, between the standpipe 42 and the discharge pipe 46, to easily separate scum trapped in the bubbles and floating from the aquarium water.

Therefore, the breeding water pumped from the pre-treatment filter 30 into the collection casing 41 first collides with the standpipe 42, and then spirals up around the standpipe 42 along with bubbles generated by ozone gas supplied from the injection tube 8 or bubbles generated by air stones, etc. During this process, organic matter, protein components, and harmful gas components such as ammonia contained in the breeding water, as well as fine solid components not removed by the pre-treatment filter 30, are captured by the bubbles and discharged in the form of scum along the guide channel 45 and discharge pipe 46. Meanwhile, the breeding water from which foreign matter has been removed is supplied to the sterilization device 50 via the standpipe 42 and supply pipe 5.

In addition to the skimmer 40 of the type described above, any type of skimmer 40 may be used as long as it can capture various foreign matter contained in the breeding water as air bubbles and remove it in the form of scum. Even when using such a skimmer 40, it is preferable to prevent the scum, which is floating debris discharged from the collection casing 41, from unnecessarily leaking to the outside. Therefore, as shown in phantom lines in Figure 8, a collection tube 47 with a predetermined storage capacity is further installed on the outside of the collection casing 41, which corresponds to the lower part of the discharge pipe 46. This allows the scum discharged from the skimmer 40 to be stored in the collection tube 47 and then processed separately. For this purpose, a drain pipe 48 equipped with a drain valve 49 is connected to the lower end of the collection tube 47.

Figures 9 and 10 show a typical example of a sterilization and disinfection apparatus 50 used in the present invention, a known water treatment device based on a plasma generator 53. The sterilization and disinfection apparatus 50 includes a reaction tank 52 for storing rearing water supplied via a pretreatment mechanism, an apparatus casing 51 installed on top of the cover plate 52a of the reaction tank 52, a control unit 57 installed inside the apparatus casing 51, and a plasma generator 53 connected to the control unit 57 and extending through the cover plate 52a of the reaction tank 52 to the lower interior of the reaction tank 52. Several to several dozen plasma generators 53 are installed to match the storage capacity (internal volume) of the reaction tank 52.

Therefore, a supply pipe 5 for breeding water that has been pre-treated is connected to the bottom of one side (left side in Figure 9) of the reaction tank 52, and a supply pipe 5 for discharging breeding water that has been sterilized and disinfected by a plasma generator 53 is connected to the top of the other side (right side in Figure 9) of the reaction tank 52. The injection tube 8 extends from the top inside the reaction tank 52, which serves as an accumulation space for ozone gas, toward the skimmer 40. The portion where the end of the injection tube 8 penetrates the wall of the reaction tank 52 is also watertight. If necessary, a small air pump can be installed on the injection tube 8.

As is well known, the plasma generator 53 has a discharge electrode 54 and a ground electrode 55 installed inside and outside the dielectric tube 56, respectively, with a reaction space 56a for generating ozone gas between the dielectric tube 56 and the discharge electrode 54. The discharge electrode 54 and the ground electrode 55 are connected to a control unit 57 via an insulating cap 53a provided on the top of the cover plate 52a of the reaction vessel 52. An air pump 58 is installed inside or outside the device casing 51, and an air injection pipe 59 extending from the air pump 58 is installed so as to communicate with the reaction space 56a between the dielectric tube 56 and the discharge electrode 54 via the insulating cap 53a of the plasma generator 53. The element designated by reference numeral 58a in the drawing is a support stand for the air pump 58.

Here, the term "dielectric" has a similar meaning to that of an insulator, but is distinguished from an insulator in that an electrical effect such as dielectric polarization is added. By placing a dielectric tube 56 between a discharge electrode 54 and a ground electrode 55, to which power is applied via a control unit 57, a dielectric polarization phenomenon can be induced between the discharge electrode 54 and the dielectric tube 56. This dielectric polarization phenomenon distributes a large amount of electric charge on the discharge electrode 54, and oxygen ( _O2 ) in the air introduced by an air pump 58 into a reaction space 56a between the discharge electrode 54 and the dielectric tube 56 reacts with the large amount of electric charge to generate a large amount of activated ozone gas ( _O3 ). The generated ozone gas escapes through an opening at the bottom of the dielectric tube 56 and diffuses in the form of fine bubbles through the breeding water stored in the reaction tank 52, thereby sterilizing and disinfecting pathogens in the breeding water.

As described above, the generation of ozone gas using the plasma generator 53 and the process of sterilizing and disinfecting pathogens are well-known technologies in the water treatment field, and therefore further detailed explanations will be omitted. In the case of a sterilization and disinfection device 50 that uses an ultraviolet lamp, ozone lamp, or electrolysis method, it can be understood that an ultraviolet lamp, ozone lamp, or electrolysis unit is installed instead of the plasma generator 53. In this case, the air pump 58 is not required, and a zigzag flow path adjustment plate or the like can be additionally installed inside the reaction tank 52 to ensure sufficient reaction time (retention time of the breeding water) between the breeding water and the ozone gas.

Figure 11 shows an example of a wastewater tank 60 used in the present invention. The wastewater tank 60 is a medium-sized container with a capacity of 1000 liters (1000 L), which is widely used in industrial settings. An exhaust pipe 66 equipped with an ozone gas neutralizing filter 67 is additionally installed on the top surface of the container. As is well known, the wastewater tank 60 as a medium-sized container has a lid 65 installed on the top end and a drain pipe 63 equipped with a drain valve 64 installed on the bottom end of one side. The tank is inserted into a framework-type storage frame 61, which has a forklift transport platform 62 installed at the bottom.

The exhaust pipe 66 allows ozone gas components degassed from the breeding water stored in the drainage tank 60 to be exhausted to the outside through a neutralization filter 67. A typical example of the neutralization filter 67 is a breathable porous body with an ozone removal layer coated on its surface. A typical example of the ozone removal layer is a mixture layer of activated carbon, titanium dioxide ( _TiO2 ), and zeolite (a porous crystal made of silicon and aluminum used as a reaction catalyst). However, any other type of filter or catalyst may be used as long as it is capable of neutralizing or removing ozone gas.

The reason why the breeding water that has passed through the sterilization and disinfection device 50 is temporarily stored in a drainage tank 60 equipped with an ozone filter exhaust pipe 66 before being finally discharged as described above is that it is nearly impossible to completely dissolve ozone gas in the breeding water inside the reaction tank 52 of the sterilization and disinfection device 50 and reduce the ozone gas concentration in the breeding water that is finally discharged to zero. Therefore, a certain level (concentration) of ozone gas is always contained in the breeding water that is discharged through the sterilization and disinfection device 50. This ozone gas can also have a negative impact on the external environment, so the ozone gas concentration in the final discharged water must be kept at a harmless level.

In other words, by temporarily storing the rearing water discharged from the sterilization and disinfection device 50 containing residual ozone gas in the drainage tank 60, the rearing water is further sterilized and disinfected by the residual ozone gas, and the residual ozone gas is degassed and neutralized. This further maximizes the sterilization and disinfection function of the rearing water, while minimizing the ozone gas concentration in the final discharged rearing water. It should be made clear that the drainage tank 60 is not limited to the form shown in Figure 11, and various other types of tank-type containers can be used as long as they can achieve this function.

With the above-described configuration, the present invention allows the rearing water stored in the aquaculture tank 2, contaminated with pathogens along with infectious organisms infected with infectious diseases, to be sucked in and transferred to the main transfer pump 3 along with the infectious organisms, where it is temporarily separated from the infectious organisms and stored in the infectious organism separation tank 20. The rearing water is then supplied to the pre-treatment filter 30 and/or skimmer 40 to remove various foreign substances from the rearing water, and is then supplied to a sterilization device 50 that uses an ultraviolet lamp, ozone lamp, plasma generator 53, or electrolysis method, etc., to completely remove even the pathogens from the rearing water.

This allows the contaminated breeding water stored in the aquaculture tank 2 to be purified and sterilized in a faster, more efficient, and more economical manner and safely discharged outside the aquaculture farm. Meanwhile, the infectious organisms separated from the breeding water in the infectious organism separation tank 20 can be collected (recovered) separately and landfilled, incinerated, or converted into fertilizer. This fundamentally prevents the recurrence and spread of aquatic infectious diseases caused by the unauthorized discharge of pathogen-contaminated breeding water, as well as the unnecessary waste of processing time and costs that would otherwise be caused by directly adding large amounts of sterilizing and disinfecting agents through the aquaculture tank 2, and secondary environmental pollution caused by the components of the sterilizing and disinfecting agents.

In particular, when using the plasma generator 53-based sterilization device 50, excess ozone gas is supplied to the skimmer 40 to create bubbles for capturing foreign matter. The breeding water discharged from the sterilization device 50 containing residual ozone gas is temporarily retained in the drainage tank 60 equipped with an ozone filter exhaust pipe 66 before being finally discharged to the outside. This allows a certain level of pathogen treatment with ozone gas to be performed in parallel in the skimmer 40 and drainage tank 60 before and after the sterilization device 50, thereby further maximizing the breeding water purification and pathogen sterilization and disinfection functions based on the sterilization device 50 and minimizing the ozone gas concentration in the breeding water finally discharged.

In addition, when the aspirator 10 having the structure shown in Figures 2 and 3 is used in connection with the main transfer pump 3, the simultaneous transfer of the culture water and infected organisms by the main transfer pump 3 can be performed more efficiently without clogging the transfer pipe 4, in accordance with the bottom condition of the aquaculture tank 2 and the level of the culture water. When the infectious organism separation tank 20 having the structure shown in Figures 4 and 5 is used, the separation of the culture water and infected organisms and the collection (recovery) of the infected organisms can be performed more easily, systematically, and reliably, without the infectious organisms excessively concentrating and accumulating at the outlet.

Additionally, the overflow pipe 7 installed in the storage tank 23 of the infectious organism separation tank 20 and the scum collection tube 47 installed on the outside of the skimmer 40 can be used to prevent unnecessary leakage of untreated contaminated breeding water and floating debris. By using a drum filter with excellent solid removal capabilities as a pre-treatment filter 30 together with the skimmer 40, various foreign substances in the breeding water fed into the sterilization device 50 can be more completely removed, minimizing breakdowns or malfunctions of the sterilization device 50 and maximizing its inherent functionality and service life.

This invention is an infectious organism removal and contaminated breeding water real-time disinfection system for aquatic organism infectious disease prevention measures, which separates infected aquaculture objects and their carcasses from the breeding water at aquaculture farms where an aquatic organism infectious disease has occurred, sterilizes and disinfects the pathogen-contaminated breeding water, and then discharges it outside the farm. This invention is an industrially applicable invention.
