Description

Water treatment device

The present invention is about water treatment device, more particularly, be about being used for collecting and remove the oil that is subject to processing water and the water treatment device of suspended substance, for example, can rely on the little eddy current, vortex filament, Hei Er (Hill) sphere eddy current, collar vortex, Kalman (Kar-man) eddy current, Taylor (Taylor) eddy current etc. of the big current that are subject to processing generation of forced circulation form in the water handled in the cabinet, vertical eddy current and turbulent form reliably and effectively with being subject to processing the water treatment device that the microorganism in the water carries out the biological process water treatment.

The present invention can be applied in the facility of storm-water drainage pumping plant, rainwater and sanitary sewage combined sewage pumping plant by same discharge of pipes and so on and sanitary sewage disposal facility effectively as water quality protection equipment.

River and lake water and industry and family domestic waste water contain a large amount of various impurity, comprise the solid particulate of oily and so on suspended substance and sand and so on.Now, the environment protection of global scale need require to accomplish in these water purifications are handled energy-conservation, concentrated, efficient and perfect.

Be used for method that water purification handles and comprise physics, chemistry and method biology.In all these methods, before carrying out purifying treatment, all need the solid particulate of the suspended substance of oil and so on and sand and so on to remove as far as possible fully, because they can damage decontamination process directly or indirectly with in the water.

Sand filtration chamber always commonly used and sump tank are removed sand and other solia particle that is subject to processing in the water, and remove wherein suspended substance with filter screen and similar device.But the use of sump tank etc. is debatable, because this class sump tank etc. will take very big place, but also because disgorging needs the expensive device of mechanism's complexity.On the other hand, when removing small suspended solids, the problem that needs expensive detailed catalogue filter screen and so on is arranged, and filter screen is often by the suspended particle blocking problem with filter screen.

As a kind of improvement to above-mentioned common method, the inventor has proposed the separator of the low and separate easily solid-liquid of a kind of expense in No.1989/85738 Japanese patent application specification sheets, in water treatment plant, use this separator, by the several rotating cylinders that horizontally rotate vertically being installed in the intimate center of sump tank and processing cabinet, deoil and suspended substance in order to remove, utilize simultaneously by rotate the mobile hydraulic performance that described rotating cylinder produces in being subject to processing water, can guarantee effective separation of solid-liquid.

With described solid-liquid trap,, can from water, separate fuel-displaced and solid particulate rapidly and reliably by containing the described rotating cylinder of rotation in the water that is subject to processing of oil, solid particulate etc.Yet, although compare with universal method without rotating cylinder, can reach the solid particulate separating effect of the suspended substance of oil and so on of obvious raising and sand and so on described separator, but under some installation site condition, the effect of the separating suspension that reaches may be desirable not enough.Find that also described separator lacks handling the adaptability of undulation in the cabinet.

Different with the chemical Treatment that causes secondary pollution easily, biological process wastewater treatment (water treatment) has obtained using widely as a kind of water treatment method of environmental sound.For example, in the activated sludge treatment process that a kind of typical biological process is handled, be in a kind of aerobic environment, to be subject to processing the sudden and violent gas of water and to carry out wastewater treatment, to improve effect and the speed that biological process is handled by making.In not adopting the oxidation irrigation canals and ditches method of sudden and violent gas, while be to make with several rotating cylinders to be subject to processing flow a long tank and make and be subject to processing water and flow through tank of water from water surface absorption oxygen.In other words, in these existent method, increase enters the oxygen amount that is subject to processing in the water and is counted as the unique way that activates the microorganism in the waste water, does not also find other effective ways that are used for activating microorganisms, and the hope that improves water treatment effect also is restricted to a certain degree.

So, the purpose of this invention is to provide a kind of water treatment device that can separate rapidly and reliably and remove the impurity that is subject to processing oil contained in the water and other suspended substances and sand and other particles and so on, and the water surface that is subject to processing water in handling cabinet keeps having good equally treatment effect under two kinds of situations of stable and fluctuation.

The present invention also aims to provide a kind of simple and low water treatment device of expense, in this device, by making the mobile of handling in the cabinet that do not stop be subject to processing and produce fast and slow current in the water forcibly, thereby creation helps microorganism activatory environment and stops by provide oxygen they to be enlivened and they are moved to microorganism, improves the effect that biological process is handled.

Above-mentioned purpose is to reach with following the present invention.The invention provides a kind of water treatment device, it comprises and has for the processing cabinet of import that is subject to processing water turnover and outlet and be used for making forcibly the rotating cylinder that water produces a kind of nascent current and follows a kind of association current that the juvenile water miscarriage gives birth to that is subject to processing in the described processing cabinet, and its characteristics are that the rotary action of reliable described rotating cylinder collects and remove the described oil in the water and/or the mechanism of other suspended substance of being subject to processing; The present invention also provides a kind of water treatment device, it comprises and having for the import that is subject to processing the water turnover and the processing cabinet of outlet, be used for making forcibly the stirrer that water produces a kind of nascent current and follows the living a kind of association current of juvenile water miscarriage that is subject to processing in the described processing cabinet, and be installed on the flowing-path of nascent current and/or the one or more turbulence generators on the flowing-path of association current, and its characteristics have been optionally to make in the described current so as to available described turbulence generator and have produced successive, the mechanism of eddy current of alternate or change, so that be subject to processing that microorganism in the water is moving moving to stop making the microorganism activation by making in the described processing cabinet, thereby make the satisfactory secretory product of described microorganisms quality.

Be subject to processing generations nascent and the association current in the water oil that is subject to processing in the water and the material of other suspended substances and sand and other solid particulates and so on will be separated rapidly and reliably by what the rotary action of rotating cylinder caused.

Suitable turbulence generator (its should be understood that generally to be meant can cause current turbulent anything) is installed on nascent current and the flowing-path with the association current of its generation can be caused producing disturbance and countless so-called vortex filaments, Hei Er sphere eddy current, collar vortex, Kalman's eddy current, the little eddy current of forms such as Taylor vortex flow, this makes the microorganism that is subject to processing in the water stand to rotatablely move again, and make the microorganism that is subject to processing in the water be parked in the area of slack water that causes by eddy current again, thereby make microorganism activation and produce the satisfactory secretory product of quality and improve being subject to processing the biological process treatment effect of water.

Though it is not clear that device of the present invention can improve the reason of biological method purification treatment effect, as if can explain like this: be subject to processing microorganism in the water and have the flagellum and the ability of ciliary movement and the habit of carrying out movement continuously is arranged with them.As a kind of means that help this motion of microorganism, in the water treatment device of the present invention, except that nascent current and association current, also ceaselessly produce the eddy current that countless sizes constantly changes, this just can cause a kind of such environment, in this environment, microorganism can rest on the regional slowly fierce activity that stands again subsequently that becomes of flowing repeatedly.

Illustrate in greater detail the present invention below in conjunction with the desirable example shown in each figure.

Shown in Fig. 1 (a), the formation characteristics of water treatment device of the present invention are to have one to handle cabinet 3 and a rotating cylinder 5, handling cabinet 3 has that current advance and effusive import 1 and outlet 2 for being subject to processing, and rotating cylinder is used for the association current 4b that produces nascent current 4a forcibly and follow described juvenile water miscarriage to give birth to.

Among the present invention, be installed in and handle that at least one diameter is different from two other diameter in each diameter of top, middle part and bottom that is subject to processing the rotating cylinder 5 in the water 7 in the cabinet 3, for example, shown in Fig. 1 (a).And, rotating cylinder 5 is driven and is flatly rotated around vertical direction by a driving mechanism (not shown) such as being fixed in the motor of handling cabinet 3, so as to the nascent current 4a that produces rotation and follow that the juvenile water miscarriage gives birth to vertical eddy current form mobile association current 4b.

Be driven and when horizontally rotating, the nascent current of the rotation of its generation are stronger than the rotary water current that the cylinder that is not had by diameter to change produces at the rotating cylinder 5 of the sort of pattern shown in Fig. 1 (a).The centrifugal force that is produced by this strong rotary water current makes and is subject to processing water and bumps against on the cabinet wall, and this makes along the water surface of cabinet wall and raises and produce a kind of very strong association current.

The peculiar rotating cylinder 5 of the present invention as long as it can rotate with desired variant rotating speed, can be got Any shape in being subject to processing water.This rotating cylinder can be got the various profiles beyond the shape shown in Fig. 1 (a).With the diameter continually varying tube shown in Fig. 1 (a) and 2 (a) or with the diameter shown in Fig. 2 (b) is not that the continually varying tube can both obtain gratifying effect.Fig. 6 shows can other various rotating cylinder profiles used in this invention.With these variform rotating cylinders, can produce very by force with vertical eddy current form mobile association current, the form of eddy current is as shown in Figure 6.And do like this to make and be subject to processing oil contained in the water and suspended substance etc. and rise to its upper layer and be collected near the top of rotating cylinder or near each wall of handling cabinet.

For example, when adopting the big rotating cylinder of top diameter shown in Fig. 1 (a), be subject to processing the central authorities at the bottom of rotatablely moving of water will make heavy sand and other solid particulate be collected to handle cabinet, the surface flow of simultaneously very strong association current will make the little oil of proportion and other suspended substance be raised to and flow to each wall of handling cabinet 3 near being subject to processing the surface of water.Sand and other solids 10 that can will be collected at centre at the bottom of the cabinet with the equipment of sand pump and so on are discharged from this system and are disposed.

On the other hand, oil and other suspended substance are with below the method for describing also being needed to handle after the overflow of processing cabinet is gone out.Under the situation of the rotating cylinder big, should just a hole groove 11 that is used to collect suspended substance be set, and on the dividing plate between hole groove 11 and the processing cabinet, adorn a door 12, and this door should be able to move up and down in the outside of handling cabinet 3 with top diameter.Like this, door 12 just can be placed on the optimal position according to the water level of handling in the cabinet 3.By the opening of door being placed on the zone below the water surface, just can making at an easy rate near the water (these water should be removed, and below will be called and should remove water) that contains big gauging and other suspended substance at top and go out from handling cabinet 3 overflows.Make then and should remove water and enter suspended substance hole groove 11, and can get rid of it with for example water pump P therefrom.

In water treatment device as shown in Figure 1 of the present invention, in handling cabinet 3, bar 14 of connection between a pair of float 13, two floats that float over the surface that is subject to processing water 7 is arranged preferably, on bar 14, fix a plurality of turbulence generators 6, shown in Fig. 1 (b) and 1 (c).This can make near the little eddy current 15 of generation turbulence generator 6, these eddy current can make oil and other suspended substance be attracted to those turbulence generators 6 easily, makes oil and other suspended substance can be from the surface that is subject to processing water more complete and easily flow in the groove 11 of hole.

When the water surface that is subject to processing water in handling cabinet 3 has fluctuation, the most handy top diameter is less than the rotating cylinder 5 that slit-shaped through hole 16 is arranged on the diameter of other parts and the sidewall, as shown in Figure 3, and will make the water treatment device of formation can guarantee to remove water will to be collected at the central authorities that handle water tank 3.As long as can reach its due effect, through hole 16 needn't be the shape in vertical slit as shown in Figure 3, but also can take the form in the slit of many levels, and these horizontal gaps can be arranged on the variant vertical position of sidewall of rotating cylinder 5.

For extract out with the water pump P that is installed in rotating cylinder 5 tops be collected at rotating cylinder 5 inside should remove water, the most handy inhalation part that can move up and down with the variation of water level, and the suction port of inhalation part should be removed water up towards the water surface so that can only aspirate out.

Referring to Fig. 4, in device of the present invention, also can on the outer wall of rotating cylinder 5, connect a floating ring 17 with homogeneous external diameter, it is dressed up to moving up and down with the sidewall of the variation of handling water level in the cabinet along rotating cylinder 5, make the molectron that constitutes by rotating cylinder 5 and floating ring 17 that the local diameter that strengthens is arranged like this.With such structure, always floating ring 17 will be positioned at the surface that is subject to processing water near processing cabinet 3, for example, shown in the dotted line among Fig. 4 (a), and it will rotate with rotating cylinder 5 on this position.Change even be subject to processing the water level of water, will become than strong near the current of handling the bottom that is subject to processing water in the cabinet near the rotary water current that is subject to processing the top of water.Therefore; in situation with the rotating cylinder 5 that has floating ring 17; also can be as situation discussed above; produce very strong nascent current and the very strong association current of following the juvenile water miscarriage to give birth to; so also can protect will contain a large amount of wet goods should remove the reliability that water is separated from be subject to processing water, and can make and should remove water and flow into suspended substance hole groove and go to carry out subsequently disposal.The plan view shape of floating ring 17 can be circular shown in Fig. 4 (b), or oval-shaped (not shown).It is a bar-shaped rotator that the rotating cylinder of using among the present invention that has floating ring can change into, like this, though efficient will reduce, can save the structure manufacturing expense.

Water treatment device of the present invention is to build with the rotating cylinder 5 of above-mentioned different shape being installed in the method for handling in the cabinet 3.Rotating cylinder 5 can be installed in or near the central authorities that handle cabinet 3, as shown in Figure 4, this situation with ordinary method is identical, perhaps is installed in an eccentric position of handling in the cabinet, as shown in Figure 5.Be installed at rotating cylinder under the situation of an eccentric position, produce current situation will be installed in or different near the situation of central authorities, its nascent rotary water current 4a will be irregular, and the association current that are vertical vortex (not shown) form of following the juvenile water miscarriage to give birth to also will be irregular.Therefore, handle that fluidised form in the cabinet 3 will not only comprise nascent current and, but also comprise the mixing of the complexity of disturbance and eddy current with the association current of its generation.This will make to be subject to processing and produce the stagnant area in the water, and this suits the requirements just, because oil-containing and the high water most probable of should removing of other concentration of suspension are collected in these stagnant areas.So the plan view shape of handling cabinet also needs not to be round, but can be as shown in Figure 5 oval-shaped, perhaps can be polygonal or long trough shaped.

Other conditions relevant with the desirable example of handling cabinet 3 are positions that water-in 1 will be set rightly, under the bigger situation of the proportion of the material that desire is separated from be subject to processing water, water-in 1 should be located at the middle place of the degree of depth of water, and under the less situation of the proportion of the isolated material of desire, water-in 1 should be located on the shallow position.Be subject to processing water and preferably flow into processing cabinet 3, the water that is subject to processing that enters processing cabinet 3 is flowed, along the wall of handling cabinet 3 to reduce most possibly to handling the mobile disturbance that is subject to processing water in the cabinet along the tangential direction of the circumference of handling cabinet 3.

Handling the structured material of cabinet 3 and capacity etc. should be according to the state that is subject to processing water, that is according to handling on-the-spot situation, being subject to processing the water yield of water and the wherein contained oil and the type and the quantity of solid particulate, again according to processing requirements and different.For example, handle cabinet 3 and can use the plastics of the metallic substance of concrete, steel plate or copper coin and so on, rigid polyvinyl chloride and so on, timber or the manufacturing of far infrared spoke line pottery, its capacity generally can be 0.5 to 500 cubic metre, but also needn't it can't be otherwise.

Also to be transferred to elsewhere after handling in the cabinet 3 and do under the situation of further processing through handling being subject to processing water, treatment facility is done as a wholely to consider from taking up room often to show that it is more appropriate that above-mentioned rotating cylinder is installed in eccentric positions of handling in the cabinet 3.

The rotating cylinder of using in the water treatment device of this suction 5, for example vertically stand under the situation about handling in the cabinet 3 at it, can drive by the gear that is fixed on the rotating cylinder top circumference by being installed in rotating cylinder motor on one side, perhaps, if can not cause problem on the layout, can be with the rotating cylinder 5 that a central shaft is arranged, described central shaft can suspend from a support that allows it freely to rotate.

The diameter of such rotating cylinder 5 should be equivalent to handle the 10-30% of the diameter of cabinet 3, its length can according to the size of handling cabinet 3 and the degree of depth etc. or according to desired processing capacity and electricity expense with between relation specifically need to consider again and different.In case of necessity, can in a single processing cabinet 3, connect or two or more rotating cylinders are installed side by side.Consider corrosion-resistant requirement, rotating cylinder 5 is the anti-biotic material manufacturing of erosion resistant material, the material that can generate electromagnetic waves or the copper and so on of handy stainless steel and so on.

As mentioned above, water treatment device of the present invention will make the heavy impurity of sand of being subject to processing in the water and so on be collected at at the end of handling cabinet, the little oil of proportion and other suspended substance are collected near the end face that is subject to processing water, and this just can reduce the content of oil, other suspended substance, sand and other solid particulates in the treated water greatly.So, for example device of the present invention is used in the preprocessing process of sanitary sewage disposal factory, and carries out various scavenging process subsequently, compare with the method for routine, can improve the validity of the decontamination process of sanitary sewage disposal factory greatly.Water treatment device of the present invention is suitable for use as the processing cabinet that activated sludge is handled, and is used as chemically treated reaction cabinet, or is used as the pre-treatment cabinet of these treatment systems.Water treatment device of the present invention is used in the facility of general storm-water drainage pumping plant or rainwater and sanitary sewage combined sewage pipe-line pumping station by same discharge of pipes and so on; can improve the quality that drains into the water in the public water system, as public water water quality protection part of work.Public in recent years water water quality protection has become a big problem.

The validity that how water treatment device of the present invention is used for improving greatly the biological process water treatment is described below.Described device comprise the processing cabinet that has for an import that is subject to processing water turnover and an outlet, one be used to force in making described processing cabinet be subject to processing the nascent current of water generates and follow the stirrer of the association current that described juvenile water miscarriage gives birth to and the flowing-path of one or more flowing-path that is installed in nascent current and/or association current on turbulence generator.In this device, described turbulence generator is to be used for optionally making current to produce the eddy current of successive, alternate or change, so that stop making their activation by the described microorganism that is subject to processing in the water is moved, thereby make the desirable secretory product of described microorganisms quality.

In other words, turbulence generator such as pole, square rod and abacus is set in the flowing-path by the nascent and/or association current that produce in the rotation by the rotating cylinder of the stirrer of above-mentioned or other patterns, for example can in being subject to processing water, causes the little eddy current of Kalman's eddy current and the unhurried current nest that leaves turbulence generator that does not have eddy current.By in this state continuously or intermittently the microorganism in being subject to processing water supply with necessary oxygen, can microorganism is moving to stop strengthening microbic activity by forcing, thus obtain the treated water of quality improvement.

In the example shown in Fig. 7, turbulence generator 6 comprises and is installed in lip-deep club outside the rotating cylinder 5, is fixed on the different turbulence generator 6 of shape on the sidewall of handling cabinet simultaneously in addition.Little eddy current just is created near these turbulence generators, shown in Fig. 7 (b).

If on the outside surface of rotating cylinder 5, install and fix the turbulence generator 6 of wall shape shown in the image pattern 8 (a) like that, and be mounted between the outside surface of itself and rotating cylinder 5 space is arranged, perhaps such shown in the image pattern 8 (b), a columniform turbulence generator is fixed in the inside of rotating cylinder 5 at the end of handling cabinet, and making between the outside surface of the internal surface of rotating cylinder 5 and turbulence generator 6 has a narrow space, Taylor (Taylor) eddy current that will generation rule in these spaces.

In the example shown in Fig. 9, there is the various difform turbulence generator such as pole and flat board to be installed on the flowing-path of handling in the cabinet 3.These turbulence generators for example image pattern 9 (a) and (b) shown in be arranged on like that on the wall of handling cabinet 3, perhaps be arranged on each other position of handling in the cabinet.

Although turbulence generator can be got the different shape shown in Fig. 9 and 11, these are installed in turbulence generator on the flowing-path of association current of the nascent current of rotating fluid form or vertical eddy current form all will cause producing disturbance and various forms of regular or irregular eddy current shown in Figure 10 and 11.The canonical form that the streamline of these eddy current is got is Hei Er sphere eddy current shown in the vortex line, the eddy current ring shown in Figure 12 (b), Figure 12 (c) shown in Figure 12 (a) and the Kalman's eddy current shown in Figure 12 (d).

There is the turbulence generator of above-mentioned different shape to be installed at of the present invention these to handle on the cabinet wall, handles in the cabinet or in the water treatment device example application on the rotating cylinder 5, except that have bigger mobile be the association current of the nascent current of rotating fluid form and vertical eddy current form, also producing in these bigger flowing has the little eddy current of all every trade Kalman eddy current as shown in figure 11, and spreads all over and handle whole in the cabinet 3 and be subject to processing water and ceaselessly produce all continuous current of variation of form and intensity continuously.Since the absorption by being subject to processing water surface or by from the disperse of handling the cabinet bottom with the oxygen distribution of necessity in entire treatment cabinet 3, microbial activities ground is stood by rotatablely moving that the eddy current in the processing cabinet 3 forms, become more regional and become more weak and mobile at eddy current, microorganism can stop again, has so just caused a kind ofly to help microbial growth and can make the microorganism more vigorous more great-hearted environment that becomes.This situation helps strengthening the vigor of microorganism, thereby improves the cleaning action to waste water.

Oxidation irrigation canals and ditches method is one of method that is generally used for the biological purification of waste water processing.A kind of like this be that sudden and violent device of air is mounted on the annular tank, allows waste water flow at the tank internal recycle on one side and purifies by sudden and violent gas on one side in the method with a kind of pattern of the long-term sudden and violent gas method of activated sludge.Used device can be cartridge type formula horizontal cartridge type formula, vertical or the drainage tube pattern.In one of its application scenario, stirrer with horizontally-arranged rotating cylinder 5 that is a kind of pattern is handled rotation cashier's office in a shop at (annular) of an elongated slot shape, in tank internal recycle process of flowing, oxygen is absorbed into to be subject to processing in the water from the water surface as shown in figure 13, and being subject to processing water (for example sanitary sewage).

When the present invention was applied to this oxidation irrigation canals and ditches method, rotating cylinder 5 certainly was the cylindrical profile of common widespread use; But the preferable rotating cylinder 5 of still using those patterns shown in Fig. 1,2 and 6, and to make at least one diameter in its top, middle part and the base diameter be different from two other diameter.Briefly bright for example shown in Figure 13 is given, to be installed in the example of handling in the cabinet 3 different vertically with those rotating cylinders 5 that these have illustrated, and in this example, the rotating cylinder 5 of above-mentioned pattern is to install horizontally.Like this, when the rotating cylinder 5 that leaks the sand hopper shape when as shown in figure 13 timing was rotated, near the place of annular water tank sidewall, promptly rotating cylinder diameter larger part produced stronger nascent current, and at the more weak nascent current of center generation near annular water tank.Along with will producing the association current that flow to the place a little less than the nascent current from the strong place of nascent current subsequently, in annular water tank, formation comprised eddy current fluidised form vertical eddy current and horizontal eddy current and complexity that be different from the eddy current on the common circulation.

In the example shown in Figure 14, the same with above-mentioned situation, rotating cylinder 5 is to be installed in the annular water tank vertically, shown in Figure 14 (b), in this case, the same with the situation of reference Fig. 7 and Fig. 9 explanation, the rotation of rotating cylinder 5 will cause producing the association current that horizontally rotate streamed nascent current and follow the living vertical eddy current form of juvenile water miscarriage.Still in this case, as situation about describing just now,, will produce than more complicated fluidised forms such as eddy current in the situation shown in Fig. 7 and 9 because the current in the annular water tank are round-robin.

And, because the turbulence generator 6 of different shape is housed in the current of the present invention's device,, also will further produce various forms of little eddy current such as Kalman's eddy current as above-mentioned each situation.Shown in Figure 13 and 14 (b), turbulence generator 6 can be installed on the path of the nascent or association current in the annular water tank, is installed on the surface of rotating cylinder, on the wall of handling cabinet or at the end.

In the present invention's oxidation irrigation canals and ditches applicatory biological process water treatment device, also can by to be installed in the annular water tank and rotating cylinder 5 on turbulence generator do special consideration on position and the shaped design, and more effectively, for example by the alternate operation of the device that makes such design, produce the turbulent flow that is similar in the nature river and the various flow-patterns of pool.In other words, can provide similar natural condition for the biological activity that is subject to processing the microorganism in the water.Therefore, in the present invention's oxidation irrigation canals and ditches applicatory biological process water treatment device, can make microorganism motion such as stand to rotatablely move, they are stopped in the unhurried current zone that eddy current has disappeared, thereby provide a kind of the very favorable treatment zone environment of microbial growth.

Under the situation that applies the present invention to the processing of activated sludge treatment process and other biological method, the processing cabinet that is subject to processing water should have an import 1 and the outlet 2 of form as shown in Figs. 7-9, import is used to receive the water that is subject to processing that flows to the processing cabinet with mobile naturally or pump supplier formula, and outlet is used to discharge treated water.The processing cabinet also should be equipped with and be used for airborne oxygen is permeated into the disperse mechanism that is subject to processing water forcibly.As long as it is suitable to handle the capacity of cabinet, to the shape of disperse mechanism without limits, it can be circular, orthogonal or oval-shaped.When adopting oxidation irrigation canals and ditches biopurification facture like that shown in Figure 13 and 14 (a), the processing cabinet of usefulness should be (annular) that the long trough of irrigation canals and ditches of growing is arranged.

Illustrate as top, the present invention relies on and handles the nascent current that produce in the cabinet and the effect of association current can be isolated " should remove water " of containing big gauging and other suspended substances and sand and other solid particulates easily and promptly, rely on by the little eddy current that turbulence generator produces is installed, this separating effect can be further improved.

Be similar to the turbulent flow in the nature river and the flow-pattern of pool by generation, application of the present invention also makes it possible to cause the environment that helps microorganism growth, this helps strengthening the mobility of microorganism, thereby quickens the cleaning action that Institute of Micro-biology rises significantly and significantly improve the effect that biopurification is handled.
