During the oxidation and organic oxidation, the circulation rate is adjusted by the sixth pump 25 according to the load amount and the wastewater treatment conditions, and the aeration tank mixed solution treated in the process is brought into contact with the anaerobic tank 7b and the first aeration tank. (8), the circulation control redox tank (100) for sending wastewater to the second aeration tank (9) is included. The circulated aeration tank mixture is then flowed to the denitrification tank (13).

In addition to being transferred to the scum tank 19, the treated water is transferred to the activated carbon filter 31 to adsorb the organic matter, SS and chromaticity through the filtration process, and then transferred to the discharge tank 32 is the final discharge.

The treatment method of high concentration organic wastewater is carried out by collecting and transporting livestock manure generated in various barns, and separating it into solid waste treatment (1), collecting wastewater to uniform concentration and flow rate, and removing wastewater. It flows into the 1-1st chamber 2a of the 1 storage tank 2. As shown in FIG.

The organic storage and VFA (Volatile Fatty Acids; volatile fatty acid, anaerobic) of urea-type nitrogen in the total nitrogen content of the first storage tank (2) in the first storage tank (2a) to increase the alkalinity, increase the retention time and the stirring ability Enzymes are produced by promoting the production of intermediate products and the release of urease enzymes. In addition, the nitrified microorganisms are introduced through the fifth pump 24 to impart deodorizing functionality to reduce the odor of the pretreatment process.

Inflow dilution of the wastewater of the floating tank 17 and the scum tank 19 transferred by the first pump 20 from the first-first (2a) and the first-second chamber (2b) of the first storage tank (2) Accordingly, the ionicity is increased to improve the treated water quality during the centrifugal separation process into the second-first chamber 4a of the second storage tank 4, and to lower the moisture content of the dehydration cake. The air stripping effect of the second chamber 2-2 (4b) of the ammonia nitrogen and 200 other volatile substances are volatilized.

Inflow of the settling SS of the treatment tank 15 increases and maintains the concentration dilution biological species and the absolute amount of BIO-MASS, and regulates the inflow of the uniform and stable wastewater through the flow adjustment tank 5, Sedimentary sludge and SS settled in the tank are returned to the first storage tank and the second storage tank to prevent the degradation of anaerobic tank and treatment function due to the change of solid inflow load and to ensure the water quality.

The metering tank 6 can directly check the conveyed amount of each kind of return water by substrate, and check the water quality and condition with milk pipe as the basis of PH, ORP, DO, temperature, alkalinity, odor, and other experimental measurements. In parallel with the physical quantity measurement through the weir method, the denitrification transfer amount, the settled transfer amount, and the inflow source water are uniformly mixed and weighed and transferred to the anaerobic tank (7).

The livestock manure pretreatment water and BIO-MASS mixed liquor transferred to the anaerobic tank (7) are dissolved in the pumping and transfer process, and the air particles introduced from the denitrification tank (13) are vented and the raw water and the return water are optimally mixed to perform the circulation process of the anaerobic tank. Going through.

At this time, various influent organic sources form the mechanism of reduction process of organic oxidation process and denitrification process.In this case, the state of anaerobic tank caused by denitrification reaction is controlled by measuring gas generation rate and pH temperature alkalinity ORP MLSS. In addition, the flow rate of the inflow water and the denitrification return, the settling return, and the inner conveyance are controlled to operate the state in the anaerobic tank with high denitrification efficiency.

Of course, in maintaining the agitation and circulation capacity in the anaerobic tank and controlling the hydrolysis rate and the organic oxidation, the denitrification function such as collecting ORP, temperature, MLSS, PH, and gas vent in connection with the following measuring instruments by automatic operation through various controllers. Can be checked and adjusted.

In addition, by injecting alkali in the anaerobic tank, by increasing the mining properties of the anamorphic chamber of the anaerobic tank, the temperature can be maintained and the photosynthetic action can be applied to enhance the denitrification function of the microorganism.

In other words, the dead volume is eliminated through the mixing process through the mixer and the circulation process through the pump, and the slope design of the bottom of the structure and the pumping chamber are installed to prevent the capacity reduction caused by the deposits in most livestock manure treatment plants. Drive to make the most of it.

In addition, the structure of the anamorphic seal (7c) through which the upper light is transmitted is secured by supplementing denitrification and alkalinity utilizing metabolic mechanisms of photosynthetic strains to secure anamorphic denitrification in the state of NO ^{2 --} N.

Systematic wastewater flow is transferred to the aerobic nitrification tank in the anaerobic and anoxic concept of total denitrification, and is randomized in the first and second aeration tanks (8,9) (early microorganisms such as bacteria and bacteria). Maintain DO operation (0.2-0.5PPM) to maintain volume load value of 0.5 ~ or more, and induce logarithmic growth of dispersed bacteria and bacteria to induce aerobic, randomness and denitrification of various microbial groups.

In particular, the high-efficiency circulation control redox tank (100) falls into the first aeration tank (8), through the defoaming function to prevent the control of bubbles and the generation of scum layer to prevent the rise of microorganisms and to improve the contact.

Furthermore, the present invention includes the integrated cooling of the aeration tank mixed liquid by adding or subtracting the circulation rate to the circulation controlled redox tank 100, and the oxidation aeration chamber 100b and the reducing anoxia at the bottom of the circulation controlled redox tank 100. After the chamber 100c is cooled, the effluent is added to the sensitized attenuator to perform organic oxidation and reduction, and the wastewater overflowed from the oxidation chamber 100b to the reducing anoxic chamber 100c is reduced in the reducing anoxic chamber 100c. It is fixed or stirred to impart a reducing function, and by connecting the sixth pump 25 for reducing the circulation of the circulation tank through circulation cooling and contact media, it continuously exerts a controlled amount of circulation with the nitrification, organic oxidation, and contact media surface biofilm. Metabolism and spawning of arbitrary states are performed to purify water quality.

In addition, when circulating and cooling the circulation control redox tank 100, using a collection duct, including a method of deodorizing the evaporated vapor and volatiles and a small amount of odor with a deodorizer, by switching the contact media to various media Seeds can also be given.

In addition, the circulation controlled redox tank 100 is circulated and cooled and nitrified to control the load fluctuations of the influent and flows into the first aeration tank 8 and the second aeration tank 9 to operate DO at 0.2-0.5 PPM to distribute Treatment stability can be obtained by increasing bacteria and bacteria proliferation and inducing random denitrification normally.

The aeration tank mixture liquid conveyed internally from the fourth aeration tank 12 is dropped through the upper portion of the highly efficient circulation control redox tank 100 to cool the water temperature increased by the denitrification heat and the organic oxidation heat generated in the continuous process to optimize the growth of activated sludges. It maintains temperature, volatilizes the toxicity of gaseous substances, touches bio-diversity of aerobic and random microorganisms while contacting biofilm (BIO-FILM) of contact media, and optionally, small-sized plants give treatment media by giving spawn media. You can also increase it.

Internal conveying pumping amount of the fourth aeration tank 12 through the three-stage anaerobic tank 7, the first and second aeration tanks 8 and 9, the anaerobic tank 10, and the third and fourth aeration tanks 11 and 12 The high-efficiency circulation control redox tank 100 is operated to control the catabolism and assimilation oxidation and reduction according to the inflow load, so that it is difficult to actively cope with high and low load load fluctuations. The odor of the pretreatment copper and the bioreactor is not a problem in a situation where proper nitrification has been achieved since it is extended to the deodorizer and distributed to the first storage tank (2).

Wastewater that has passed to the first and second aeration tanks (8, 9) finds reducibility and undergoes denitrification, and the microbial group has reduced the abundance of probiotic microorganisms by reducing the aeration of the third aeration tank (11) and the aeration of the fourth aeration tank (12). It proliferates to welfare microorganisms and undergoes stable nitrification, and the denitrification tank (13) secretes reduced-state metabolism polymers that prevent denitrification through residual organic sources and rising in sedimentation tanks. Keep it.

The aeration tank mixed liquor which has passed to the settling tank 14 is separated into solid-liquid and the fixed supernatant is transferred to the treatment tank 15, and the lower sedimented sludge is transferred to the anaerobic tank 7 via the metering tank 6 to remove the denitrified biomass (BIO). -MASS).

By passing through the settling tank 14 to the treated water tank 15 made of a blowing and sedimentation functional structure, it is settled after intermittent blowing, and returned to the first and second storage tanks 2 and 4, It supplies the dilution ability of waste water and spore-like Bacillus strains, and provides the decomposing organic matter supply and the pretreatment function of biological seeding by degrading microorganisms, thereby providing absolute biomass (BIO-MASS) in denitrification process that lacks C / N ratio. It will play a role.

In other words, the SS flowing over from the treated water tank 15 is impregnated with intermittent aeration, and microorganisms are separated into solid-liquid, and the precipitated MLSS is properly sent to the first and second storage tanks to secure seed spawning and remaining organic sources of reconstituted microorganisms. The total amount of BIO-MASS can be increased.

The treated SS component after the bioreaction of high concentration organic wastewater contains a very large amount of MLSS component, so as to protect the loss of MLVSS as much as possible, giving seeding effect and biological pretreatment effect through blowing in the flow control tank, and anaerobic tank (7) As it enters into, it is possible to increase the decomposition ability by microorganism as much as possible.

This is a method to reduce the cost of the spawning agent which continuously inserts spawn, and it is a method to secure the biological treatment stability by reducing the load fluctuation, and to improve the water quality of the treated water after the sedimentation tank (14), improving the TN removal rate and sludge generation It has the expected effect of reducing the risk.

In addition, the problem of sedimentation and sedimentation of sediment sludge caused by high concentration of organic wastewater is accumulated through long residence time, and the lower part of each tank is constructed with a cone, and the solids are pumped to the first and second storage tanks (2, 4). It transfers intermittently to rise and prevents load fluctuations causing solid load, contributing to stable processing.

In the flotation tank, after the chemical treatment through the coagulation of inorganic coagulant in the range of PH 2-4 strong acid, and the method to separate the solid-liquid separation by pressurized flotation, the waste water of the treatment tank 15 is introduced into the advanced treatment through the chemical treatment. Iron salts are used in (17) to react in the strong acid PH band 2 ~ 4 to break off the macromolecule rings remaining difficult to decompose in the wastewater. TN and TP will be removed. At this time, 30% ~ 50% of the flotation treated water can be returned to the water tank before treatment, and the treatment water quality can be obtained very well when continuous treatment is applied by applying the circulation rate.

On the other hand, the decomposition, denitrification and dephosphorization of organic matter by metabolic action of aerobic microorganisms in the first, second, third and fourth aeration tanks (8, 9, 11, 12) are as follows.

First, the aerobic microorganism is activated under an overaeration condition, and the bioabsorbing capacity of the food ingredient is introduced into the aeration tank. The decomposition process of organic matter by the metabolic action of the aerobic microorganism in the aeration tank is expressed by the following equation.

_{C5H7ON (bacteria)}

Organics + O ₂ → CO ₂ + H ₂ 0 + new microbial cells.

The amount of growth of new cells according to the amount of BOD removed is about 0.5 kg MLVSS / kg BODrem.

On the other hand, ammonia nitrogen is nitrified as follows.

                   _{Nitrosomonas Nitrosomonas )}

NH ₄ ⁺ + 3 / 2O ₂ → ^{_{NO 2 - + H 2 O +}} 2H +

_{Nitrate bacteria ( Nitrobacter )}

^{_{NO 2 - + 1 / 2O 2}} → NO 3 -

Nitrification of 1 mg / L ammoniacal nitrogen consumes 4.6 mg O ₂ / L of oxygen and 7.1 mg CaCO ₃ / L of alkali.

As described above, by checking the alkalinity of the inlet and outlet of the aeration tank and adjusting the dissolved oxygen amount to about 0.2 to 2.0 mg / L, especially about 0.5.-1.0 mg / L, the rapid nitrification is suppressed to inhibit the nitrification due to the lack of alkalinity. To prevent.

The aeration tank mixed liquid conveyed internally from the fourth aeration tank 12 and introduced into the high efficiency circulation control redox tank 100 has a nitrification rate at aeration rate and aeration rate of the aeration tank and the storage tank at the inflow load of the first aeration tank 8. Can be determined according to the administrator's pattern according to the load variation.

Dephosphorous microorganisms that release phosphorus in the cell in the form of phosphate consume a relatively higher amount of phosphorus when synthesizing cells under an aerobic atmosphere in an aeration tank.

For example, the amount of phosphorus (P) released by the dephosphorous microorganism in the form of phosphoric acid and the amount of phosphorus (P) ingested by the dephosphorous microorganism in an aerobic atmosphere in the aeration tank are maintained at a ratio of about 1: 1.5.

Therefore, when cells of dephosphorus microorganisms are synthesized in the aeration tank, phosphorus (P) is excessively ingested in the cells (luxury uptake) to perform the dephosphorization process.

By using the selectively activated dephosphorus microorganisms to improve the dephosphorization capability of the wastewater treatment apparatus, it is possible to minimize the chemical consumption required for the dephosphorization process through the flocculation process on the pressurized portion described later, thereby improving water quality.

In the denitrification tank, the denitrification process is performed through the endogenous respiration of microorganisms using untreated organic matter and nitrogen oxide and sludge contained in the mixed solution flowing from the aeration tank.

            ^{Denitrifying cocci ( Denitrifier )}

_{^{NO 3 - + 6H + → 1}} / 2N 2 + 3 / 2O ₂

In other words, the denitrification process produces oxygen 2.86g O ₂ / g N and alkalinity 3.6g CaCo ₃ / g N, and the residence time of the denitrification tank is about 1.5 to 2 days, and the denitrification rate of this process is 0.03g N / g. MLVSS / d.

After the denitrification process, the wastewater flows over the denitrification tank and enters the circular sedimentation tank through the discharge port.

When the supernatant separated from the sedimentation tank is introduced into the treatment tank, the chemical inorganic coagulant such as divalent metal salt is injected and reacted to coagulate and solid-liquid separated into a pressure flotation tank.

The reaction scheme for removing residual phosphorus by chemical treatment is as follows.

_{^{Fe 3 + + PO 4 3 -}} → Fe (PO 4)

That is, the residual phosphorus in the supernatant reacts directly with iron (Fe) in the iron salt and is removed as an insoluble salt.

In addition, iron in the iron salt reacts with the hydroxyl group (OH ⁻ ) of the supernatant to form an iron hydroxide salt and precipitates out as shown in the following reaction formula.

^{Fe 3 + + 3 (OH -} ) → Fe (OH) 3

The sludge generated by scum is transferred to the 1-2 chamber of the first storage tank, mixed with the wastewater, and then dehydrated by improving the ionicity, thereby lowering the concentration of the desorption solution, reducing the sludge water content, and greatly reducing the sludge treatment cost of the process. Sludge is dehydrated with low water content, favored by recyclers.

Therefore, the treatment device and treatment method of high concentration organic wastewater should be low cost, low energy economy and load fluctuation, quick and convenient to cope with it, and no additional cost or very little treatment should be fundamentally stable.

In this respect, the present invention is natural and applicability is very encouraging.

The present invention is a wastewater treatment technology that allows for stable water quality management by continually and stably incorporating water treatment site conditions and establishing convenient control methods for denitrification, dephosphorization, reducing, and concentration reduction of water quality managers.

First, anaerobic reduction denitrification conditions

During wastewater treatment, the microbial state of the continuously circulated conveying zone is induced to the reduced state (keeping it in anoxic and spore state), securing anoxic crude volume (㎥), applying the triple structure and the stirring and increasing method, and controlling the influent conveying state and quantity By design and construction to control the production of enzyme and improvement of denitrification efficiency, it prevents trouble in anaerobic tank and treats high concentration organic (waste, manure) wastewater.

It combines the functions of famous Anamox (ammonia nitrogen) denitrification and nitrate nitrogen denitrification, and gives daylight conditions, thereby utilizing the photosynthetic metabolism of microorganisms and the requirements of energy (electricity) and chemical (organic carbon source). Greatly reduced the cost.

In addition, an arbitrary first and second aeration tanks (8, 9) are placed between the aerobic tank and the denitrification tank, so that the microorganisms are installed in the treatment system to have the metabolic ability of the amphoteric (aerobic and anaerobic) substrates. Structural specificity, alkalinity replenishment facility, and securing of microbial photosynthetic metabolic capacity of the provincial state not only maintain the biological reduction continuously but also allow the objective observation of the denitrification state for efficient and functional control.

Second, aerobic nitrification conditions

Due to the characteristics of high concentration wastewater, many problems of nitrification and organic oxidation process occur according to the impact load of influent. Therefore, this method is a highly efficient circulating redox tank (internal circulation capacity, media seeding, sensitizer, anaerobic, deodorization, volatilization, reaction heat). The system is excellent in coping with high concentration organic wastewater treatment by promoting the nitrification and organic oxidation by increasing and decreasing the internal transport water and circulation rate during the load fluctuation period through the construction of cooling effect). I will say.

The expected effect on the system is

-Increase the DO and maintain the biological optimum by reducing the temperature of the aeration tank raised by the heat of reaction.

-Cost of cooling energy, which was required at high cost, is unnecessary and maintenance is very easy.

-As circulating water comes into contact with media, microbial diversity is given in anaerobic, aerobic, and random conditions, and the microbial system for influent wastewater is formed, which makes the treatment stable.

-By controlling DO (0.2-0.5) of random aeration operation, it maintains proper temperature range by using primitive microbial metabolism system such as bacteria and dispersed bacteria and leads to maximum metabolic rate to give high functionality of nitrogen consumption through cell synthesis.

-Effective volatilization of volatile gaseous substances in the intake manure and aeration tank mixture through contact scattering to increase its decomposition rate and help activate activated sludge.

-The microbial growth of catabolism and assimilation is secured, and the decomposition ability of organic matter is greatly improved.

-By controlling NOx by increasing instantaneous nitrification rate, it maintains stable discharge water quality such as T-N, and then makes high quality treatment water at low energy cost in advanced treatment field.

Third, the C / N ratio is compensated for by maintaining and increasing BIO-MASS, and the impact load is reduced.

Since the SS component of the treated water after the bioreaction tank of high concentration organic wastewater contains a large amount of MLVSS component, it is transferred to the treatment tank made of the BLOWING and SEDIMENTATION functional structure after the sedimentation tank, settled after blowing, and returned to the storage tanks 1,2. It supplies the dilution ability of raw wastewater and spore-like Bacillus strains before entering into bio-coagulation, and deodorization and asset supplying undecomposed organics of microorganisms and pretreatment of biological feeding.

As a result, the loss of MLVSS is maximized and retained in the anaerobic and aeration tanks to maximize the decomposition ability by microorganisms.

This is a way to reduce the cost of the spawning agent that keeps spawning continuously, and has the expected effect of improving the removal rate of sludge after the settling tank and reducing the amount of sludge generated.

 In addition, the sludge formed as the high concentration of organic wastewater is stored through a long residence time is applied to the lower part of each tank, and a pump chamber is installed to transfer the solids to the storage tank to prevent load fluctuation of the treatment plant through intermittent solid load. Contribute to stable processing.

 This eco-friendly method uses biological treatment to ensure the stability of water quality. For the treatment of high concentration organic wastewater (treatment of manure and manure, which is a non-degradable wastewater) and wastewater treatment facilities, pretreatment state control and nitrification rate control anaerobic operation control It is a low cost and high efficiency wastewater treatment technology that has been designed to enable the operation control of each function such as the post-stage process chemical treatment rate control to secure the stepwise operation capability of water quality management, and to enhance the operation convenience in the field of difficult decomposable wastewater treatment, which has been considered difficult.

Fourth, the use of the ALUM series inorganic coagulant, which has been used a lot for the ozone treatment facility during the advanced treatment process, has the effect on the clarification of water quality, but it is less than the removal rate of chemical reaction due to the weak oxidizing power compared to iron salt. In view of this, treated water using iron salt in the coagulation of chemical reaction, but using about 10% more iron salt than reaction equivalent, reacts with soluble iron and ozone in ozone process afterwards, and has strong oxidizing power in the same way as Fenton treatment method. By reacting with -RADICAL, iron salt can be applied to ozone treatment than ALUM series inorganic coagulant. In addition, after ozone treatment, the treated water forms sludge, so that the treated line has an appropriate sedimentation tank after polymer line mixing, and the COD / BOD / SS / TN / TP and color removal are better when the activated water is filtered. Water quality can contribute significantly to wastewater treatment systems.
