Description

[0001] The present invention relates to a sewage treatment apparatus and an advanced sewage treatment method, and more particularly, to a sewage treatment apparatus and an advanced sewage treatment method, filter medium Manufactured by Method}

The present invention relates to a method for treating and removing various contaminants such as organic substances, suspended substances and nutrients contained in sewage treatment plants, wastewater treatment plants, factory wastewater treatment plants, and sewage and wastewater flowing into individual wastewater treatment facilities by a biological treatment method A sewage elevation treatment apparatus and a treatment method thereof.

Accordingly, the present invention provides a bio-reactor integrated management system using ICT, which includes pH, NH ₄ -N, MLSS and dissolved oxygen (DO) sensors and an operation control device, The operation condition of the reactor can be monitored in real time by the seasonal and time-dependent sewage inflow, influent's pH (pH) and dissolved oxygen (DO) concentration, and the air supply volume and nitrogen circulation volume of the oxic tank can be automatically controlled This is characterized by reducing the installation cost of the facility, reducing the area of the required site, and reducing the power consumption of the bioreactor.

In addition, the present invention provides a device capable of producing renewable energy such as solar and wind power at a sewage treatment plant free area in order to prevent deterioration of nitrogen and phosphorus removal efficiency due to lowered water temperature of the inflow sewage in winter, The present invention is characterized in that the removal efficiency of nitrogen and phosphorus is supplied to a heating device for raising the temperature of the water in the winter bioreactor so that the stability of the treated water quality is maintained.

In addition, the present invention provides a system for remotely monitoring the operation state of a sewage treatment plant by utilizing the latest IT technology such as a smart phone, a PC, a CCTV, a notebook computer, etc., It is designed to enable quick initial action through alarm provisioning and SNS notification in the event of an emergency, and to reduce the manpower by introducing a system that can monitor and control the operation and control of main equipment remotely / unattended. .

In general, sewage, wastewater, and rainwater contain various pollutants such as organic matter, suspended matter, nitrogen, and phosphorus. When discharged without proper treatment, they cause water pollution and eutrophication of discharged water, I am crazy.

To overcome these problems, these pollutants are usually treated by biological treatment with microorganisms in public treatment facilities.

Meanwhile, when nitrogen and phosphorous contaminants are treated by the conventional biological treatment method, the energy required to supply the air required for microbial growth of the bioreactor takes up about 40% of the energy required for the entire treatment plant.

However, the conventional bioreactor can not grasp the state of the process in the process of nitrification and denitrification in real time (there is not enough system to control the amount of air supply and the amount of nitrification liquid circulation) It is impossible to properly cope with the change, and the efficiency of the treatment is inevitably ensured. As a result, there is a possibility of exceeding the water quality standard of effluent water. Therefore, when designing the existing bioreactor, It is designed to be somewhat more than the required capacity.

In other words, the energy cost for operating the sewage treatment plant accounts for more than 40% of the total power ratio, so that the energy cost can be reduced by optimizing the air supply to the bioreactor There is an increasing need for technology development. In recent years, automation of operation management and technology for enabling further stabilization of treated water quality are also required.

On the other hand, in order to solve the above-mentioned problem, the invention patent for the denitrification and nitrification of the biological reactor (patent 10-0432518 / 2004.05.11. Registration - hereinafter referred to as "conventional patent") has been devised.

These prior patents are directed to a wastewater treatment system and method for performing continuous denitrification and nitrification at low dissolved oxygen (DO) concentration conditions below 0.6 mg / L in a single reactor.

Therefore, a main technical point of the conventional patent is that a sensor part composed of a dissolved oxygen (DO) sensor, a pH (pH) sensor and an electron transfer coenzyme sensor is installed in the single active reaction tank, An oxygen depletion rate control valve, a variable blower, and an oxygen supply unit. The oxygen supply unit is electrically connected to the sensor unit, and calculates a BPA change amount and a pH change amount by a built- And a control unit for controlling the operation of the oxygen supply unit and the mixer is provided to be electrically connected to the reaction determination unit, Value to determine whether denitrification and nitrification are to be terminated.

However, these conventional patents are somewhat complicated in the monitoring and control apparatus due to the technology for increasing the nitrification and denitrification effect by the air supply amount and the flow rate control by the electron transfer coenzyme sensor (NADH sensor) or the attachment of the copper sensor. , It is difficult to confirm the effect of nitrification and denitrification on the efficiency and economical efficiency of the technology compared with existing anaerobic, anoxic and anaerobic techniques.

In other words, taking into account the decrease in the total nitrogen and total phosphorus removal efficiency due to the lowering of the water temperature of the influent water flowing into the sewage treatment plant during the winter season (from December 1 to March 31), the discharged water quality standard for the pollutants was relaxed However, since the total nitrogen and total phosphorus accumulated in the winter season are pointing to eutrophication in the summer season, the government revised the related laws and started to apply the emission standards for nitrogen and phosphorus from July 17, 2014 It is urgently required to develop a technique for improving treatment efficiency of the pollutant in the winter season.

In addition, apart from the previous patents, the latest market is equipped with remote monitoring and control system that incorporates the latest IT technology, and solar energy is used in the spare area of the sewage treatment plant to generate new and renewable energy, There is an urgent need to develop a new and advanced technology that can be used as a high-

The filtration apparatus 350 includes a filtration enclosure 351 for performing downflow high-speed microfiltration on contaminants not removed from the secondary settler 300, A filtrate water discharge pipe 351-2 and a discharge valve 351-3 capable of automatically adjusting the discharge flow rate and regulating the flow rate are formed at a lower side of the filtration enclosure.

At this time, a multifunctional eco-friendly sand filter media 353 provided with a backwashing device 352 is stacked by a strainer support body 354 inside the filter housing, and a filtration water supply pipe 351-1 is connected to the upper end of the filtration housing A tributary trough 357 is formed.

The filtration device 350 includes a water level sensor 355 and a backwash water outlet 356 at one side and the other side of the filtration housing and the environmentally friendly sand filter media 353 stacked on the strainer support body 354 is thick The gravel layer and the thin sand layer are formed so as to have the upper and lower layers.

In order to discharge the filtered water generated in the backwashing process to the backwash water discharge port 356, a side discharge valve 356-1 is formed on one side of the filtration water, and a backwash water The backwash water upper discharge valve 357-1 may be formed to discharge the backwash water to the discharge port 356. [

The strainer support 354 includes a plate panel 354-2 having a plurality of engagement holes 354-1 formed therein and the strainer member 354-3 is assembled to the engagement hole 354-1. .

At this time, the strainer member 354-3 is formed with hollow tubes 354-31 through which the both ends of the strainer member 354-3 branch out from the upper and lower surfaces of the plate panel 354-2 through the fitting hole 354-1, 354-31 are formed such that threads are formed on the outer circumferential surface and the upper side grill cones 354-32 and the lower side tightening nuts 354-33 are joined.

Between the grill cone 354-32 and the tightening nuts 354-33 is formed an air discharge plate 354-35 having exhaust grooves 354-34 so that when the high pressure air flows in backwashing, And does not remain in the dust receptacle 354-3 and is discharged to the exhaust grooves 354-34 at all times so as not to cause air bubbles in back washing in order to prevent leakage of the multifunctional environmentally friendly sand filter media 353 .

More specifically, in the past, after filtration backwashing with air to desorb the suspended matter trapped in the filtration media of the filtration enclosure, air remaining in the lower portion of the strainer member resulted in excessive filter media.

That is, in the process of discharging the backwash water, the lower residual air flows out to the upper part together with the filter material. The wastage of the strainer member is wide (W = 1.5 mm) and the basic filter medium is composed of gravel (5-10 mm) 2.5 to 5 mm), which causes some fine filter media to be lost through the lower support layer.

This is because the grain size of the multifunctional eco-friendly sand filter media is 0.4 to 1.4 mm, which is partly lost to the bottom through the yarn, gravel layer and strainer.

Therefore, in the conventional strainer member, the filter material is backwashed with air, and the reverse material is flowed from the lower part to the upper part to float the filter material, and then the suspended material flows into the lower part of the filter material in the filter material stabilization process. The suspended solids are discharged for a certain period of time (5 minutes), so that the water quality deteriorates.

In order to solve this problem, the present invention forms an exhaust groove, which is a structure capable of discharging the residual air remaining in the lower portion of the strainer in the backwashing process, so as to prevent filter material loss by residual air.

To this end, the strainer member of the present invention has a diameter of 1.5 mm at the strainer member that is installed in the prior art, so that the multi-functional environmentally friendly sand filter media has a particle diameter of 0.4 to 1.4 mm, so that the filter media may flow out to the lower portion of the strainer member. The air gap is changed to 0.5 to 0.8 mm while the exhaust groove is formed to prevent the filter material from being lost to the bottom during backwashing.

As described above, the filtration apparatus is a downflow filtration apparatus that is fed from the secondary settler downward from the top to the bottom, and is configured to be filtered while passing through the multifunctional environmentally friendly sand filter media.

In this case, the position of the filtered water inlet pipe of the filtration device should be set in consideration of the maximum water level of the backwash water supply during the backwash of the filtration layer, and an automatic valve capable of controlling the inflow flow rate and the inflow flow rate And is formed so as to be dispersed in the filter housing.

That is, the filtration device is formed on the upper side of the filter as a water level sensor such as a wire type water level meter and an ultrasonic water level meter so as to detect disturbance of the filtration layer due to partial concentration fall of inflow water and to detect the filtration water level and filtration speed.

On the other hand, the filtration layer structure of the filtration apparatus will be described in more detail. The filtration layer structure of the filtration apparatus is composed of a strainer support to which a plurality of strainer members are coupled, a gravel layer, a coarse sand layer, a thin sand layer and a multifunctional environmentally friendly sand filter media.

At this time, the strainer member is installed at a predetermined interval so as to prevent the gravel, coarse sand, fine sand, and multifunctional eco-friendly sand media seated on the strainer member from flowing out below the filtration layer and sufficiently discharging the filtration water to the outside .

In addition, the strainer member is provided not only to prevent gravel, coarse sand, fine sand, and multifunctional eco-friendly sand filter media from leaking, but also to move the air and backwash water evenly upward when the filter layer is backwashed It also helps to help.

A discharge valve for discharging filtration water to the outside is installed under the strainer support. The discharge valve 351-3 has a regulating function capable of automatically adjusting the amount of filtration discharged on the filtered water, It is preferable to provide a diffuser and an apparatus for supplying backwash water.

The backwashing device 352 of the filtration device 350 is installed on the lower side of the filtration enclosure 351 so that the high pressure air is sprayed to the diffuser 352-12 by the blower 352-11. A pump 352-21 and a reverse tubule 322-22 are connected to the other side of the lower side of the filtration enclosure 351 to receive washing water through an inverter on the disinfection discharge side to perform backwashing, And a reverse reciprocating device 352-2 having a reciprocating motion.

More specifically, if the filtration rate is slowed or the amount of the exhaust gas is significantly reduced because the pollutant to be deposited on the multifunctional eco-friendly sand filter media can not be filtered any more, the level of the raw water in the microfilter is increased.

At this time, the inside of the filtration apparatus filtration enclosure is formed to measure changes in the level and the flow rate with respect to the filtrate water of the filtration enclosure by means of a sensor such as a wire type water level meter or an ultrasonic water level meter.

For example, when the filtered water is heated by the fluctuation of the filtered water level, more specifically, the predetermined level or higher, the detector senses the filtered water, and the treated water filtered through the filter layer is discharged to the outside through the water tube 351-2 do.

At this time, when the flow rate of the filtered water is measured in real time or irregularly, if the flow rate of the filtered water to be discharged along the water tube does not reach the preset flow rate, the filtration is stopped and the filtered water remaining in the filtered body is filtered The water is discharged to the outside of the filtration housing through the filtered water side discharge valve 356-1 and the backwash water discharge port 356 installed on the side of the housing and then flows backward from the bottom of the filtration housing toward the filtration layer portion Provide wash water.

As an optional example, the backwashing facility is to inject air first to completely separate the pollutants collected in the multifunctional environmentally friendly sand filter media from the filter media, and then to supply the backwash water to the multifunctional environmentally friendly sand filter material Multifunctional eco-friendly sand filter media with a large specific gravity is precipitated first and the suspended particulate matter is discharged to the outside of the filter.

The backwash water is injected in a direction opposite to the flow direction through which the backwashing supply flow rate is adjusted by the inverter device, and the multi-functional environmentally friendly sandwiched filter material, So as to prevent the clogging of the filtration layer portion by separating contaminants attached on the surface thereof.

The contaminants separated by the backwash float over the filtration layer and are discharged through the backwash water upper discharge valve 357-1 and the backwash water outlet provided in the upper side overflow trap of the filtration enclosure to the effluent storage tank. The discharge valve is formed at the end of the inlet trough device so that the multifunctional environmentally friendly sand filter media is not lost to the outside by the vortex of backwash drain water.

At this time, if the air supplied in the backwashing process remains below the lower support of the filtration enclosure, the residual air is discharged to the upper portion of the filtration layer portion in the discharge process of the contaminants, so that a part of the multi-function environmentally friendly sand filtration media floats upwards and is discharged together with the discharge water So that the lower support strainer of the filtration housing is provided with a groove-shaped cross-sectional structure which can completely remove the residual air above the filtration layer in the course of supplying the backwash water.

The disinfection and discharge tank (360) includes a disinfection device (361) for disinfecting various bacteria including Escherichia coli to the treated water flowing out of the filtration device; A water quality measuring device 362 for detecting set values (pH, BOD, COD, SS, T-N, T-P, and coliform group compliance values) according to water quality standards of effluent water of treated water; A discharge flow meter 363 for measuring the discharge flow rate of the treated water whose water quality has been measured; .

The sewage treatment apparatus may further include a remote monitoring and monitoring system 500 for monitoring and controlling the operation status through an IT device including a smart phone, a PC, a CCTV, and a laptop in real time.

In the meantime, the present invention is capable of performing the sewage elevation treatment method using the above-described sewage elevation treatment apparatus, and is characterized in that the above-described first settling tank 100, the bioreactor 200, the second settler 300, Management system 400 comprises: (NOx) concentration in the nitrification and denitrification zone based on the NH ₄ -N, MLSS, pH, and dissolved oxygen (DO) concentrations in the oxic tank, The concentration of NH ₄ -N, NO ₃ -N, MLSS, pH, and dissolved oxygen (DO) measured by the method described above is increased or decreased by a set value of a certain range, And the air supply amount and the pH (pH) set value according to the load variation are automatically converted.

Accordingly, the biological treatment tank comprehensive management system 400 can respond to the operation of the blower by the DO set value when the blower (air supply) is fully operated and the pH value is maintained within 40 minutes to 1 hour The data of influent load variation of seasonal wastewater is sensed and stored so as to secure the optimum value of the blowing amount of the blowing apparatus according to seasonal influent load fluctuation, and the seasonal optimal pH value is set to be automatically operated .

In addition, the biological treatment tank comprehensive management system 400 can determine the water quality on the upstream side of the aerobic tank as a pH meter and can be determined as a water quality index or can be determined based on organic matter, TN, NO ₃ -N, And NH ₄ -N. If the measured values of the pH meter, organic matter, TN, and NH ₄ -N in the air upstream of the influent upstream side exceeds the target value, the air amount of the blowing device (PH) meter, organic matter, TN, and NH ₄ -N concentration in the aerobic reactor upstream of the influent are less than the target value, If the measured values of the oxidation-reduction potential and the NO ₃ -N concentration in the air upstream of the influent upstream air-conditioning unit exceed the target value, the blowing amount of the blowing unit is reduced to induce denitrification. When the measured values of the oxidation-reduction potential and the NO ₃ -N concentration in the upstream-side aerobic tank are smaller than the target value, the amount of air in the blowing unit is increased to correspond to an appropriate value for the influent load.

In addition, the biological treatment tank comprehensive management system 400 can measure the dissolved oxygen (DO (DO) concentration in the aerobic tank in the range of 0.5 to 2.0 mg / L and the DO concentration set value required to nitrify the dissolved oxygen ) Concentration and a pH (pH) concentration sensor are used to control the amount of air supplied to the bioreactor while sensing the change in the real time pH value of the oxic tank.

The effluent of the primary clarifier and the phosphate in the transport sludge recovered from the secondary clarifier are mixed with activated sludge microorganisms And is decomposed in the anaerobic state to release phosphorus.

The anaerobic tank 210 includes a stirrer or an underwater stirrer 211 for allowing a shaft having a plurality of blades to be rotated by a drive motor so as to prevent sedimentation of the transfer sludge introduced from the secondary settler; A bypass channel 212 for allowing the influent water to flow directly without passing through the primary clarifier if it is determined that the organic material is insufficient in the interior; A sludge supply line 213 in which a series of supply lines are formed to receive sludge from the primary settler as needed; .

At this time, the inlet 221 is formed such that the nitrifying liquid is introduced from the end of the oxic tank.

In addition, the stirring device or the water stirrer 222 is formed so that a shaft having a plurality of blades is rotated by a driving motor so as to prevent precipitation of the nitrification solution introduced from the aerobic tank and thereby prevent decay.

At this time, the aeration device 223 is formed at one side of the agitation device to prevent precipitation of nitric acid solution and corruption.

The carbon supply device 224 is formed to supply an external carbon source including methanol.

In other words, when the nitrifying liquid is introduced into the anoxic tank by the internal circulation facility at the effluent of the anaerobic tank and the end of the oxic tank, the denitrifying microorganism performs the process of denitrifying the nitrogen gas into organic nitrogen gas. The nitrogen is removed by a denitrification reaction in which the chemically bonded oxygen is circulated internally from the aerobic tank to the nitrifying liquid and is converted into nitrogen gas (N ₂ ) by the denitrifying microorganisms.

The denitrification reaction in which the nitrate nitrogen (NO ₃ ^- ) contained in the returned nitrified liquid under the anoxic condition is converted into nitrogen gas (N ₂ ) is as follows.

* Denitrification: 2NO ₃ ^- + 2 (H ₂ ) 2NO ₂ ^- + 2H ₂ O

2NO ₂ ^- + 3 (H ₂ ) N ₂ + 2OH ^- + 2H ₂ O

The residence time of the anoxic tank is about half to 1.5 hours shorter than that of existing anaerobic, anaerobic and arsenic techniques, taking into account the characteristics of the present invention that compensate for the lack of denitrification after performing nitrification and denitrification in the aquarium. As the net exchange rate is reduced to 40 ~ 100%, the capacity of the anoxic tank can be reduced to a maximum of 1/4 of that of the existing method.

The anoxic tank is equipped with an aeration device or an agitation device and is configured to be able to stir using air or a stirrer to prevent decay due to sedimentation of sludge in an anoxic tank and a device for supplying an external carbon source such as methanol Device is formed.

As shown in FIG. 2 or FIG. 4, the aerobic tank 230 is a schematic cross-sectional view of an aerobic tank for nitrification and denitrification of nitrogen, and is formed to remove untreated residual organic matter in an anaerobic tank and an anoxic tank.

The aerobic tank 230 is further provided with a blowing unit 231 and a solids retention time management unit 232.

That is, the blowing facility 231 is a process of simultaneously performing nitrification and denitrification of sewage by the microbial treatment, and it is required to constitute at least three sets, and the concentration of the pH (pH) and the dissolved oxygen (DO) (PH) sensor and dissolved oxygen (DO sensor) sensor, and determines the amount of air blown to the nitrification and denitrification zone based on the set value. The air amount is increased or decreased to adjust the pH and dissolved oxygen ) Concentration.

In other words, the aerobic tank is oxidized to nitrate nitrogen by the nitrifying bacteria retained in the 'biological reaction tank integrated management system utilizing ICT', nitrogen contained in the primary clarifier effluent that has passed through the anaerobic tank and the anoxic tank.

In addition, the nitrate nitrogen is reduced by the anaerobic bacteria in the activated sludge as nitrogen donor, and the organic matter in the inflow sewage and the organic matter adsorbed in the sludge are removed as nitrogen gas.

In addition, part of the mixed solution containing nitrogen oxidized at the end of the aerobic unit such as cyclic denitrification method, anaerobic, anaerobic, and arc method (about 40% to 100% of nitrification liquid circulation rate) is circulated in the anoxic tank and is denitrified. Also, the nitrate nitrogen contained in the sludge of the secondary clarifier is also partially de-nitrified in the anaerobic tank.

At this time, the aerobic tank allows ammonia nitrogen (NH ₄ ⁺ ) to be nitrified with nitrate nitrogen (NO ₃ ^- ) under an aerobic condition, and the reaction is as follows.

* Nitrification: NH ₄ ⁺ + 3 / 2O ₂ NO ₂ ^- + 2H ⁺ + H ₂ O

NO ₂ ^- + 1 / 2O ₂ NO ₃ ^-

Since the aerobic unit generates nitrification and denitrification at the same time by the 'integrated bioreactor management system utilizing ICT', the unit group of the oxic tank is composed of at least three sets for efficient nitrification and denitrification, and the residence time of the oxic tank is 7 hours 8 hours.

5 is a schematic cross-sectional view of a blowing unit 231 for supplying air to the oxic tank. The air blowing unit 231 is provided with a diffuser 231 for reducing the energy of the oxic tank, which occupies about 40% There is an urgent need for a countermeasure for improving the oxygen delivery efficiency of the air supplied from the air supply system.

In order to achieve this, it is necessary to increase the contact area between air and water by making the particle size of the air supplied from the blower to be in the form of micro-bubbles or ultra-high-strength bubbles, 231-2) and the like.

At this time, as shown in FIG. 2 or FIG. 6 to FIG. 9, the secondary settler 300 is formed so as to precipitate and remove the flocs generated in the aerobic basin in a gravitational manner and to transport or withdraw the sludge.

The sludge pit 310 is formed in the secondary sedimentation tank 300 to collect sedimented sludge at the center.

The sludge transport device 320 is formed at one side of the sludge pit and the sludge is transported to the anterior part of the anaerobic tank 300.

At this time, the secondary settler has a MLSS densitometer 330 for measuring the MLSS concentration. The MLSS concentration meter 330 is further provided to determine the SS concentration in real time, and then to calculate the amount of surplus sludge necessary for the sludge concentration, A surplus sludge discharging device 340 for transferring the excess sludge; Respectively.

As shown in FIG. 7, the secondary settling basin 300 can be highly refined to treat pollutants including untreated organic substances, suspended substances, and phosphorus in the treated water, and can be reused for river maintenance water or other purposes A filtration device 350 is further provided.

That is, in order to efficiently reuse the limited water resources to riverside water, agricultural water, landscape water, industrial water, road water, and flush water for toilet, etc., the organic matter, Phosphorus and the like are formed to form flocs by the coagulation reaction of the chemicals and then subjected to an advanced filtration treatment with water quality suitable for the purpose of reuse.

At this time, the filtration apparatus 350 is formed with a filtration enclosure 351 for performing a downflow high-precision microfiltration on the contaminants not removed from the secondary settler 300, and one side of the filtration enclosure 351 A filtrate water tank 351-2 and a discharge valve 351-3 capable of automatically adjusting the discharge flow rate and regulating the flow rate are formed at a lower side of the filtration enclosure.

At this time, a multifunctional eco-friendly sand filter media 353 provided with a backwashing device 352 is stacked by a strainer support body 354 inside the filter housing, and a filtration water supply pipe 351-1 is connected to the upper end of the filtration housing A tributary trough 357 is formed.

The filtration device 350 includes a water level sensor 355 and a backwash water outlet 356 at one side and the other side of the filtration housing and the environmentally friendly sand filter media 353 stacked on the strainer support body 354 is thick The gravel layer and the thin sand layer are formed so as to have the upper and lower layers.

In order to discharge the filtered water generated in the backwashing process to the backwash water discharge port 356, a side discharge valve 356-1 is formed on one side of the filtration water, and a backwash water The backwash water upper discharge valve 357-1 may be formed to discharge the backwash water to the discharge port 356. [

The strainer support 354 includes a plate panel 354-2 having a plurality of engagement holes 354-1 formed therein and the strainer member 354-3 is assembled to the engagement hole 354-1. .

At this time, the strainer member 354-3 is formed with hollow tubes 354-31 through which the both ends of the strainer member 354-3 branch out from the upper and lower surfaces of the plate panel 354-2 through the fitting hole 354-1, 354-31 are formed such that threads are formed on the outer circumferential surface and the upper side grill cones 354-32 and the lower side tightening nuts 354-33 are joined.

Between the grill cone 354-32 and the tightening nuts 354-33 is formed an air discharge plate 354-35 having exhaust grooves 354-34 so that when the high pressure air flows in backwashing, And does not remain in the dust receptacle 354-3 and is discharged to the exhaust grooves 354-34 at all times so as not to cause air bubbles in back washing in order to prevent leakage of the multifunctional environmentally friendly sand filter media 353 .

More specifically, in the past, after filtration backwashing with air to desorb the suspended matter trapped in the filtration media of the filtration enclosure, air remaining in the lower portion of the strainer member resulted in excessive filter media.

That is, in the process of discharging the backwash water, the lower residual air flows out to the upper part together with the filter material. The wastage of the strainer member is wide (W = 1.5 mm) and the basic filter medium is composed of gravel (5-10 mm) 2.5 to 5 mm), which causes some fine filter media to be lost through the lower support layer.

This is because the grain size of the multifunctional eco-friendly sand filter media is 0.4 to 1.4 mm, which is partly lost to the bottom through the yarn, gravel layer and strainer.

Therefore, in the conventional strainer member, the filter material is backwashed with air, and the reverse material is flowed from the lower part to the upper part to float the filter material, and then the suspended material flows into the lower part of the filter material in the filter material stabilization process. The suspended solids are discharged for a certain period of time (5 minutes), so that the water quality deteriorates.

In order to solve this problem, the present invention forms an exhaust groove, which is a structure capable of discharging the residual air remaining in the lower portion of the strainer in the backwashing process, so as to prevent filter material loss by residual air.

To this end, the strainer member of the present invention has a diameter of 1.5 mm at the strainer member that is installed in the prior art, so that the multi-functional environmentally friendly sand filter media has a particle diameter of 0.4 to 1.4 mm, so that the filter media may flow out to the lower portion of the strainer member. The air gap is changed to 0.5 to 0.8 mm while the exhaust groove is formed to prevent the filter material from being lost to the bottom during backwashing.

As described above, the filtration apparatus is a downflow filtration apparatus that is fed from the secondary settler downward from the top to the bottom, and is configured to be filtered while passing through the multifunctional environmentally friendly sand filter media.

In this case, the position of the filtered water inlet pipe of the filtration device should be set in consideration of the maximum water level of the backwash water supply during the backwash of the filtration layer, and an automatic valve capable of controlling the inflow flow rate and the inflow flow rate And is formed so as to be dispersed in the filter housing.

That is, the filtration device is formed on the upper side of the filter as a water level sensor such as a wire type water level meter and an ultrasonic water level meter so as to detect disturbance of the filtration layer due to partial concentration fall of inflow water and to detect the filtration water level and filtration speed.

The filtration layer structure of the filtration apparatus is composed of a strainer support to which a plurality of strainer members are coupled, a gravel layer, a coarse sand layer, a thin sand layer and a multifunctional environmentally friendly sand filter media.

At this time, the strainer member is installed at a predetermined interval so as to prevent the gravel, coarse sand, fine sand, and multifunctional eco-friendly sand media seated on the strainer member from flowing out below the filtration layer and sufficiently discharging the filtration water to the outside .

In addition, the strainer member is provided not only to prevent gravel, coarse sand, fine sand, and multifunctional eco-friendly sand filter media from leaking, but also to move the air and backwash water evenly upward when the filter layer is backwashed It also helps to help.

More specifically, if the filtration rate is slowed or the amount of the exhaust gas is significantly reduced because the pollutant to be deposited on the multifunctional eco-friendly sand filter media can not be filtered any more, the level of the raw water in the microfilter is increased.

At this time, the inside of the filtration apparatus filtration enclosure is formed to measure changes in the level and the flow rate with respect to the filtrate water of the filtration enclosure by means of a sensor such as a wire type water level meter or an ultrasonic water level meter.

For example, when the filtered water is heated by the fluctuation of the filtered water level, more specifically, the predetermined level or higher, the detector senses the filtered water, and the treated water filtered through the filter layer is discharged to the outside through the water tube 351-2 do.

At this time, when the flow rate of the filtered water is measured in real time or irregularly, if the flow rate of the filtered water to be discharged along the water tube does not reach the preset flow rate, the filtration is stopped and the filtered water remaining in the filtered body is filtered The water is discharged to the outside of the filtration housing through the filtered water side discharge valve 356-1 and the backwash water discharge port 356 installed on the side of the housing and then flows backward from the bottom of the filtration housing toward the filtration layer portion Provide wash water.

As an optional example, the backwashing facility is to inject air first to completely separate the pollutants collected in the multifunctional environmentally friendly sand filter media from the filter media, and then to supply the backwash water to the multifunctional environmentally friendly sand filter material Multifunctional eco-friendly sand filter media with a large specific gravity is precipitated first and the suspended particulate matter is discharged to the outside of the filter.

The backwash water is injected in a direction opposite to the flow direction through which the backwashing supply flow rate is adjusted by the inverter device, and the multi-functional environmentally friendly sandwiched filter material, So as to prevent the clogging of the filtration layer portion by separating contaminants attached on the surface thereof.

The contaminants separated by the backwash float over the filtration layer and are discharged through the backwash water upper discharge valve 357-1 and the backwash water outlet provided in the upper side overflow trap of the filtration enclosure to the effluent storage tank. The discharge valve is formed at the end of the inlet trough device so that the multifunctional environmentally friendly sand filter media is not lost to the outside by the vortex of backwash drain water.

At this time, if the air supplied in the backwashing process remains below the lower support of the filtration enclosure, the residual air is discharged to the upper portion of the filtration layer portion in the discharge process of the contaminants, so that a part of the multi-function environmentally friendly sand filtration media floats upwards and is discharged together with the discharge water So that the lower support strainer of the filtration housing is provided with a groove-shaped cross-sectional structure which can completely remove the residual air above the filtration layer in the course of supplying the backwash water.

As shown in FIG. 2, the control system of the integrated management system using ICT, which is a technical point of the present invention, will be described below.

First, NH ₄ -N, pH and dissolved oxygen (DO) sensors were installed in the aerobic tank, and MLSS sensors were installed in the sludge pit of the secondary clarifier.

Using the results of the measurement by each sensor, the operation control device controls the air volume of the nitrification denitrification condition by adjusting the amount of blown air by each air volume control valve installed in the air piping through the comprehensive management of the ASRT and the state of the oxic tank, Denitrification reaction at the same time.

In order to manage nitrification nitrification required for nitrification by ICT-based bioreactor management system, the NH ₄ -N, DO sensor was used for NH ₄ -N, pH, MLSS, DO sensor It is installed in the mountain area divided by the vertical pipe at the end of the oxic tank.

In addition, an air volume control valve of an appropriate air amount increase / decrease device is installed in the mountainous region divided by the vertical pipe, and the angle control of the airflow volume control valve installed in the vertical pipe is executed to execute the number of blowers and the output control.

The pH sensor installed at the end of the oxic tank is used as an index of operation for performing nitrification denitrification in the oxic tank, and when the nitrification reaction proceeds in the oxic tank, the alkalinity is consumed and the pH is lowered.

In the 'Integrated Bioreactor Management System using ICT', nitrification reaction occurs until the pH value reaches the set value, and denitrification reaction proceeds when the pH value reaches the set value or more.

FIG. 10 is a schematic illustration of an operation control device of the 'integrated biological reaction tank management system using ICT'.

In the 'integrated biological reaction tank management system utilizing ICT', the configuration of the operation and control apparatus is largely composed of an enclosure, an undercarriage, a CPU operation unit, an instruction unit, a power supply unit, an input unit and an output unit, and a peripheral device.

Accordingly, the enclosure protects various components from being hindered by the moisture while protecting the interior parts from being hindered.

At this time, the inner box is formed to provide a CPU operation unit, an instruction unit, an input unit, an output unit, and a peripheral device in the operation control device.

The CPU arithmetic unit is configured to decode a program stored in the memory of the arithmetic control unit or to execute processing contents.

Thus, the power supply device is configured to supply power to each component of the arithmetic and control unit.

In this case, the input unit is a part for detecting the state of the external device or instructing the movement of the external device through the operation panel, It is formed so as not to be transmitted to the CPU side.

In addition, the output section transmits an external contact to an electronic contactor or a solenoid connected to the outside of the operation control device to move an external device or display a state, and uses the transistor output exclusively for direct current power supply in consideration of frequent opening and closing of contacts .

Thus, the peripheral device is formed to record a program in a memory of the arithmetic and control unit.

FIG. 13 is a flow chart for controlling the blowing amount of the oxic tank with respect to the pH value and the dissolved oxygen (DO) value. When the pH value of the oxic tank is below the set value, the blower operation is stopped and the denitrification operation is performed If the set value is set, the denitrification operation is performed while maintaining the blower operating state at the current level. If the pH value is equal to or higher than the set value, the blower is operated to perform the nitrification operation.

If the dissolved oxygen (DO) value of the oxic tank is equal to or lower than the lower limit of the set value, the operation of the blower is increased. The operation is performed after reducing the air supply amount for the nitrification operation.

FIG. 14 shows an example of a control panel in the nitrification and denitrification step of the oxic tank. When the pH value of the oxic tank is shifted to a set value or more, the valve angle due to the nitrification progress instruction such as NOx denitration notification is opened at 100% The actual measured value of dissolved oxygen (DO) is 100% (blowing amount 100%), 98% (blowing amount 90%), 96% (80%), 4 stage output 94% (70% wind output) and 5 stage output 92% (60% wind output).

In addition, when the pH value is shifted to a set value or less, the valve angle due to the denitrification progress instruction such as NOx denitration notification is closed at 20%.

At this time, the amount of blowing air supplies the minimum blowing amount necessary for blower stop and denitration regardless of the measured value of dissolved oxygen (DO).
