Description

Treatment method and apparatus for high concentration wastewater containing livestock manure {TREATMENT METHOD AND APPARATUS FOR WASTEWATER INCLUDE EXCREMENTITIOUS MATTER OF DOMESTIC ANIMAL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wastewater treatment apparatus, and more particularly, to a method and apparatus for treating high concentration wastewater for treating high concentration wastewater such as livestock manure (livestock wastewater).

Conventionally, when high concentration wastewater such as livestock manure is treated by aerobic microorganisms, it is common to treat high concentration wastewater by installing a bioreactor (aerobic tank) and an anaerobic tank. In high concentration wastewater treatment, a large amount of foam is generated in a bioreactor (aerobic bath). To remove this, conventionally, a defoaming agent is used, or a treated water or effluent is sprayed using a pump and a defoaming pipe or a nozzle.

However, the high concentration wastewater treatment method has a disadvantage in reducing nitrogen removal performance, and in the case of using an expensive antifoaming agent (silicone solution) for defoaming, there are disadvantages of economic problems and a decrease in treatment efficiency due to overuse. If a large amount of spraying using treated or effluent is used to remove the foam, high concentrations of wastewater will dilute and increase the hydraulic load, causing management problems such as the need to expand the size of the wastewater treatment plant.

Accordingly, it is an object of the present invention to provide a method for treating high concentration wastewater and a device for enhancing the removal efficiency of a large amount of bubbles generated in purifying the high concentration wastewater including livestock manure and increasing the nitrogen removal rate.

Another object of the present invention is to disinfect and remove harmful elements that adversely affect the growth of microorganisms such as disinfectants, antibiotics, and high concentrations of nitrogen in livestock manure, which is suitable for livestock manure treatment and continuously and stably supply the adapted microorganisms. To provide a processing method and apparatus.

In accordance with the above object, the present invention, in the treatment method of high concentration wastewater containing livestock manure, while pretreated high concentration wastewater through an anaerobic tank 1, aerobic tank 1, anoxic tank 2, aerobic immersion membrane tank having an immersion membrane Denitrification in the anoxic tank and nitrification in the aerobic tank are carried out, but the active microorganism and the oxygen free one tank are treated between the activated microorganism and the high concentration wastewater introduced into the anoxic tank 1 in an active microbial tank supplied with highly active external sludge. The water is repeatedly circulated, and the reaction liquid in the aerobic tank 1 and the reaction liquid in the aerobic immersion membrane tank are returned to the treatment tanks of each front end so as to be defoamed.

In addition, the present invention, in the treatment of high concentration wastewater containing livestock manure, each of the high concentration wastewater pre-treated in the pre-treatment unit portion, while passing through an anaerobic immersion membrane tank having an oxygen-free tank 1, aerobic tank 1, anoxic tank 2, immersion membrane Comprising a main treatment facility for denitrification in the anoxic tank and nitrification in each aerobic tank, the one oxygen-free tank is connected to the active microbial tank through a circulating pipe to circulate the treated water and the active microbial tank is highly active external sludge It is configured to be supplied, and the inlet of the inner conveying pipe having an internal conveying pump to each of the exhalation tank and the exhalation immersion membrane tank, respectively, and the outlet of the inner conveying pipe in each of the shear treatment tanks of the exhalation tank 1 and the aerobic immersion membrane tank Position the line and each of the discharge port line is characterized in that the number of the surface of the defoaming nozzles are installed.

In the present invention, the active microbial tank is separately placed during aerobic biological treatment of high concentration wastewater, such as livestock manure, to increase the treatment efficiency of high concentration wastewater, such as livestock manure, and to enable stable operation. The pipe is installed in the loop at the edge of the reactor and the closed-flow control foam nozzle is installed to effectively remove bubbles from the surface of the bioreactor, and the biomass for high concentration wastewater treatment, such as livestock manure, is installed in the final aeration tank. Remove E. coli. In addition, the solid-liquid separation by the membrane can simplify the post-treatment process and maintain stable treatment water quality superior to the legal effluent water quality standards. In addition, no sedimentation, filtration, and disinfection processes are required, which saves electricity costs and makes it possible to use as a heavy water, and the last treated water that has passed through the final biofilm passes once again through a flocculation settling tank, ozone contacting tank, and sand filter. High concentrations of wastewater can be treated.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

When treating high concentration wastewater such as livestock manure as aerobic biological, the aerobic tank (biological reaction tank) usually uses the A ² O method, which is modified from the MLE method or the AO method, which is an anaerobic-aerobic activated sludge method. Most of these types of processes are usually configured to allow nitrification to occur in an aerobic tank and to react nitrified by nitrification to an anoxic tank via a pump so that denitrification occurs in an aerobic bath.

However, when the high concentration organic wastewater, including livestock manure, is treated using the general method, aerobic microorganisms are difficult to treat stably due to antibiotics and impact loads contained in the high concentration wastewater, and treatment efficiency is low. In addition, when the microorganism is in poor condition, excessive bubbles are often generated and normal operation is often impossible. As such, very few organic wastewater treatment facilities, including livestock manure, employing the A ² O method or the MLE method are rarely operated smoothly.

In the present invention, in the construction of high concentration wastewater treatment facilities such as livestock manure, an active microbial tank is installed to secure microorganisms that can withstand and live well in high concentration organic wastewater, and the active microbial tank is a sewage treatment plant or a wastewater treatment plant, a manure treatment plant. Implement the device to increase the microbial activity in the entire treatment facility by continuously flowing the sludge with high activity, which can be easily obtained from the back, and mixed with the return sludge of the treatment facility to comply with aerobic conditions.

In addition, in order to effectively operate while preventing excessive bubbles in the reaction tank, an internal return pump is installed in the aerobic tank and the aerobic immersion membrane tank, and a plurality of antifoam nozzles are provided in the outlet port line of the internal conveying pipe to prevent flow and control the flow rate. It is characterized in that it is configured to remove the bubbles generated in, to effect the effect of internal transport, surface aeration, temperature lowering.

Active microbial tank (18), oxygen-free tank 1 (14), aerobic tank (20), oxygen-free tank 2 (22) using the defoaming nozzles 48 located at the discharge ports of the inner conveying pipes (42) and (44). Spraying the treated water returned to the inside of the air defoaming removes bubbles in the treatment tank and lowers the temperature, as well as achieving homogenization of suspended microorganisms that may be different for each treatment tank.

Referring back to Figure 1, the high concentration wastewater, such as livestock manure is stored in the livestock manure storage tank (10) and is pretreated to filter the livestock hair, contaminants, fine feed grains, etc. while passing through the pretreatment facility (12), the After that, it flows into the anoxic one tank 14 which is the main treatment facility part 2 of this invention.

High concentration wastewater such as livestock manure flowing into the first anaerobic tank 14 includes harmful elements that adversely affect the growth of microorganisms such as disinfectants, antibiotics, high concentrations of nitrogen, and the like, and a strong odor unique to livestock manure occurs.

In the embodiment of the present invention to implement the decomposition and removal of harmful elements adversely affecting the growth of microorganisms, and suitable for livestock manure treatment and to continuously and stably supply the adapted microorganisms, An active microbial tank 18 is installed at the front end, and a circulation pipe P1 and P2 are connected to the active microbial tank 18 and the first anoxic tank 14 so as to be compliant.

In addition, the active microbial tank 18 is configured to continuously input high active external sludge, which can be easily obtained from a sewage treatment plant, a wastewater treatment plant, or a manure treatment plant, through the sludge tank 16, and aeration port 52 to maintain aerobic conditions. Aeration device including) is installed inside, and the reaction liquid from the aerobic tank 1 is returned.

Since the external sludge flowing into the active microbial tank 18 may not be suitable as a microorganism suitable for the treatment of organic high concentration wastewater such as livestock manure, in the embodiment of the present invention, the aerobic tank of the main treatment facility 2 The reaction solution exhaled at 20 is sprayed and supplied through the small nozzle 48 which is conveyed through the inner conveying pump 40 and the inner conveying pipe 42 and sprayed into the active microbial tank 18, The reaction solution and sludge with high activity, which can be easily obtained from the sewage treatment plant, wastewater treatment plant, and manure treatment plant, which are introduced from the outside, are mixed, and are adapted to be suitable for organic wastewater treatment such as high concentration livestock manure while staying in aerobic conditions for a certain time.

The activated sludge, which is equal to the amount of returned sludge and the amount of activated sludge injected from outside of the aerobic tank 20, introduced into the active microbial tank 18, is transferred from the active microbial tank 18 to the first oxygen-free tank 14 through a connecting pipe. It flows in between the active microbial tank 18, one anaerobic tank 14, and one aerobic tank 20.

In addition, in the active microbial tank 18, the reaction liquid exhaled in the first aerobic tank 20 is conveyed through the inner conveying pump 40 and the inner conveying pipe 42 to be sprayed into the active microbial tank 18. Since the injection is supplied through the defoaming nozzle 48, it can be implemented as an energy-saving facility that can achieve the sludge conveying effect, surface aeration effect, defoaming effect at the same time.

The active microbial tank 18 constitutes a storage tank about five times the daily inflow of high concentration wastewater such as livestock manure, and the circulation amount for the compliant transport between the active microbial tank 18 and one anoxic tank 14 is 1 aerobic tank ( It is preferable to continuously circulate as the amount of conveyed sludge (10 times the daily inflow) of 20).

Meanwhile, in the anoxic one tank 14 of FIGS. 1 and 2, the livestock manure introduced from the pretreatment facility unit 12, the concentrated filtrate introduced from the concentration tank 28 of the main treatment facility unit 2, and the first stage aerobic tank 20 (20). After passing through the inner conveying pump 40 and the inner conveying pipe 42 in the primary conveying water to be sprayed and supplied through the small nozzle (48), the inlet through the circulation pipe (P2) in the active microbial tank (18) The active microorganisms are agitated and mixed in the anoxic state with the stirrer 50 to denitrify the nitrogen nitrated in the aerobic tank 1 with the organic matter (carbon source) of livestock manure. That is, in the oxygen-free one tank 14, nitrogen oxides (NO _X ⁻ ) included in the returned water are reduced to nitrogen gas by denitrification microorganisms under anoxic conditions, and released into the atmosphere to finally remove nitrogen.

In the embodiment of the present invention, in order to efficiently use the organic matter contained in the livestock manure, an anoxic one tank 14 is installed at the front of the aerobic tank 1 so that the organic material may be preferentially used in the denitrification process. This is an installation structure that takes into consideration nitrogen removal as it is difficult to secure proper C / N ratio for denitrification because the characteristics of domestic manure are relatively high compared to organic concentration.

As a result of mixing and acclimatization with active microorganisms in an anaerobic trillion (14), organic matter and nitrogen concentrations in high concentration wastewater such as livestock manure are reduced by the action of denitrification microorganisms, and livestock manure treated in anoxic trillion (14). The treated water flows into the aerobic tank 20.

In the aerobic tank 1 (20) is supplied to the livestock manure treatment water treated by the anaerobic tank 1 (14) by the air abandoned by the aeration port 52 to remove the organic matter by aerobic microorganisms and nitrification by the nitrification microorganism. Odor and foam rapidly occur due to the characteristics of livestock manure during aerobic process, resulting in lowering of aerobic treatment efficiency and secondary pollution by odor. In order to cope with this, in the embodiment of the present invention by returning the stabilized secondary return water from the back end immersion membrane tank 24 by defoaming through the defoaming nozzles 48 installed in a loop type on the top of the reaction vessel by removing the bubbles and odor removal At the same time as well as maximizing aerobic treatment efficiency. Furthermore, it is possible to solve the above-mentioned defoaming spray of the upper nozzle nozzle (48), which is not easy to stir up or down the reaction tank of the tank 1 (20) due to the viscosity of the livestock manure or high concentration of suspended solids.

Livestock manure treatment water treated in aerobic tank 1 (20) is introduced into the anaerobic tank 2 (22).

In the anaerobic tank 2 (22), the livestock manure from which organic matter and nitrogen were first removed from the first stage anaerobic tank / aerobic tank and the secondary return water returned through the internal return pipe 46 from the aerobic submerged membrane tank 24 at the rear stage are mixed. Denitrification occurs. Nitrogen oxide (NO _X ⁻ ) contained in the secondary return water is reduced to nitrogen gas by the denitrification microorganism under anoxic conditions, and released into the atmosphere. Finally, nitrogen in the treated water is finally removed.

Installation of the internal conveying pipe 42 or the foam nozzle 48 for spraying the parcel water into the active microbial tank 18 and the oxygen-free one tank 14 of the main treatment facility section 2 of FIG. 1 and FIG. Simultaneous removal of bubbles maximizes the nitrification of the aerobic tank and increases the biological treatment efficiency by reducing the dissolved oxygen supply by surface aeration and the temperature inside the bioreactor. The defoaming nozzle 48 of the present invention has a large opening and can be adjusted in an open and closed manner so that there is almost no clogging of the nozzle even in the viscosity of the livestock manure and the adhesive of the solid agent. The cost of electricity and mechanical installation is much lower than the method used for parcel water.

The livestock manure treatment water treated in the anaerobic two tanks 22 flows into the aerobic immersion membrane tank 24 having the livestock manure dipping membrane 26.

In the aerobic immersion membrane tank 24, the organic matter is removed by aerobic microorganisms by supplying the air abandoned by the aeration port 52, and at the same time, nitrification of residual nitrogen is performed by the nitrification microorganisms. Inflow water flowing into the aerobic immersion membrane tank 24 is a state in which most organic matter is removed, the volume of the aerobic immersion membrane tank 24 is implemented relatively less than the treatment tank of the front end.

The livestock manure immersion membrane 26 immersed in the aerobic immersion membrane tank 24 is a hollow fiber membrane for separating solids and liquids, and is 20 to 30 times the volume of the aerobic immersion membrane tank 24. It consists of about%.

The livestock manure immersion membrane 26 is configured to mount a plurality of hollow fiber membrane modules in one frame, and an air diffuser 27 is located at the bottom of the frame, and a discharge pipe is positioned at the top of the frame. To control the sludge deposition.

The immersed hollow fiber membrane of the present invention for solid-liquid separation constituting the immersion membrane 26 has a fractional characteristic with a pore of 0.1 to 1 탆 (preferably about 0.4 탆). Activated sludge in the aerobic tank shows distribution characteristics with peaks in the particle distribution near 0.5 μm and 1.5 μm, and there are almost no particles below 0.07 μm. Therefore, it can be simply determined that the pore size of the immersion hollow fiber membrane is 0.07 μm. However, the hollow fiber membrane having a pore of 0.1 to 1 μm (preferably about 0.4 μm) as in the present invention because a thin deposition layer is formed on the immersed hollow fiber membrane section of the aerobic immersion membrane tank to form a dynamic membrance. The effect of using a 0.07 μm pore separation membrane is shown.

In addition, the present invention uses a slit-shaped hollow fiber membrane having a porosity of more than 70% of the hollow fiber membrane, this membrane structure is only 0.05 ^~ 0.07m ³ / m ² air cleaning without adopting a backwashing process to increase the permeation rate of the separation membrane High concentrations of livestock manure can be carried out with a high flux of day.

The immersion membrane 26 may be manufactured in the form of a rectangular cartridge to adjust the number of stages of the hollow fiber membrane module according to site conditions, and the detachment of the immersion membrane module may be simplified. Biofilm for high concentration organic matter treatment can be separated into high solids without chemical reaction facilities and reduces contaminants by simply and completely removing suspended solids (SS) and E. coli from treated water. The treatment film is intended to enable continuous use without long-term cleaning, not disposable. In the present invention, the solid and liquid separation by the immersion membrane can maintain the MLSS (Mixed Liquor Suspended Solid) concentration of 10,000 ~ 15,000mg / ℓ, and also prevents the loss of nitrifying microorganisms with low growth rate, thereby increasing the nitrification rate of ammonia, Phosphorus absorption by condensed microorganisms also occurs.

The present inventors have measured the oxygen uptake rate (OUR: Oxygen Uptake Rate) in the aerobic immersion membrane tank 24, which is the final treatment tank of the main treatment facility 2, and has a range of 10 to 32 mg / L / hr. SOUR: Specific Oxygen Uptake Rate was 1.0-2.2 mg / MLVSS / hr. This is higher than the oxygen intake rate in the general activated sludge process, it was confirmed that the microbial activity in the aerobic immersion membrane tank 24 is considerably high.

As shown in FIG. 1, the membrane treated water passing through the livestock manure affixation membrane 26, which is the final stage of the main treatment facility section 2, is a flocculation sedimentation tank 32, an ozone contacting tank 34, and a sand filter ( Through 36), it is discharged as final treated water.

In the flocculation sedimentation tank 32, hardly decomposable organic matter (a substance causing chromaticity containing organic matter such as humic acid or digestive enzymes of livestock) of the treated water separated by the immersion membrane 26 for livestock manure in the aerobic immersion membrane tank 24 , Organic nitrogen and biologically unremovable phosphorus are removed by reacting with ferric chloride, caustic soda and polymer coagulant to precipitate.

The ozone contact tank 34 decomposes the pollutants to the water quality standard that meets the water quality standards of the livestock manure co-processing plant by oxidizing and removing the non-degradable organic substances, colors, and bacteria which have not been removed from the coagulation sedimentation tank 32 with ozone having a strong oxidizing power. Remove In the sand filter 36, when a contaminant such as organic matter, phosphorus, and chromatic acid is oxidized in the ozone oxidation process of the ozone contact tank 34, contaminants condense to form a small amount of suspended solids. Filtered.

In the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.
