Description

Process for Sewage treatment by humix reaction

The present invention is to remove the organic matter, nitrogen, phosphorus and odors and pathogens by using soil corrosion in the treatment of sewage wastewater, and to treat wastewater and wastewater by the corrosion reaction which can recycle the treated water and by-products. It is related to the advanced treatment process, and more specifically, the soil microorganisms are concentrated and multiplied to produce corrosive sludge, and the corrosive sludge is reflected to the treatment system to realize more effective and thorough corrosive reactions, resulting in organic matter and nitrogen. The present invention relates to the physicochemical and biological treatment of wastewater and wastewater by the removal of phosphorus, the removal of odors and pathogens, and by the corrosive reactions that can recycle treated water and by-products.

In the sewage and wastewater treatment methods, many processes have been developed and applied to remove organic matter, nutrients, odors and pathogens. Among them, there is no doubt that the activated sludge method is a basic technology that was developed as a biological treatment method focused only on the removal of organic substances that are aerobic oxidized and low molecular weight and then applied to most of sewage and wastewater treatment.

However, the activated sludge method and its variations, such as long-term aeration, step aeration, contact conversion, rotational disk, sprinkling water phase, and pure oxygen, are aerobic biological treatment methods using aerobic microorganisms. Low molecular weight circuit for gasification, decay, and oxidative decomposition of organic matters by feeding, sedimentation, and sedimentation. Satisfying organic matter removal efficiency, but decay of treated water, lack of nitrogen and phosphorus removal efficiency, separate sterilization facility, sludge decay , Excessive amount of sludge is generated and sludge flocculant, sludge resources are not available, sludge concentration / digestion tank is needed, installation cost and site are large, complex treatment system, difficulty of operation management, excessive operation manpower, And disadvantages such as high operating expenses, severe odors, need for separate odor removal facilities, and eutrophication of the stream ecosystem. All.

In addition, several methods have been developed to remove nitrogen and phosphorus, which are the causes of eutrophication of sewage and wastewater. For example, A / O method, A ² / O method, UCT method, SBR method, VIP method, MLE method, Bardenpo method and the like.

These processes have been developed to more efficiently remove nitrogen and phosphorus in the form of dissolved and particulate ammonia or organic nitrogen through several stages of treatment. However, most of these treatment mechanisms are nitrified by nitrifying bacteria in aerobic conditions for nitrogen, denitrified by denitrifying bacteria in anoxic conditions, and released in the air for phosphorus release, and ingestion of phosphorus to release phosphorus in anaerobic conditions and excess phosphorus removal in aerobic conditions. (Luxury Uptake) theory is adopted.

Nitrogenation is Nitrosomonas ( Nitrosomonas ) changes ammonia to nitrous acid using oxygen (O ₂ ), Nitrobactor ( Nitrobactor ) to change the nitrous acid to nitric acid, the reaction process is shown in Scheme 1.

^{_{NH 4 + + 1.83O 2 + 1.98HCO}} 3 - → 0.021C 5 H 7 NO 2 + 1.041H 2 O + 0.98NO 3 - + 1.88H 2 CO 3

Denitrification involves microorganisms such as Pseudomonas , Micrococus , Archromobacter , Thiobacillus , Bacillus , etc. have.

The microorganism uses the carbon source as the electron donor and the nitrogen oxide as the electron acceptor in the absence of oxygen, and in the presence of free oxygen, this microorganism can cause deterioration of the denitrification rate. Because of this property, denitrifying bacteria are called aerobic bacteria. Luxury Uptake of Phosphorus is obtained by decomposing Poly-P accumulated in the cell in the anaerobic state to obtain energy, and using this energy to intake organic acid to obtain poly-β-hydroxybutyl acid. Store in the form of (PHB) and release free orthophosphate to the body. When changed to aerobic state, the phosphorus-removing microorganism decomposes the stored PHB to synthesize ATP, and consumes phosphorous acid to synthesize poly-P. The microorganism to the Acinetobacter (Acinetobacter), micro nose Syracuse, Pseudomonas and the like, biological removal requires a sufficient amount of organic matter. However, these processes had many disadvantages such as increase of construction cost, increase of operating cost, complexity of treatment process, and deterioration of treatment efficiency, and also could not perform odor removal inherently.

In addition, treatment methods using soil microorganisms and treatment methods using Bacillus bacteria in organic wastewater treatment such as sewage and sewage are known. The treatment method using soil microorganisms is a method of treating soil microorganisms by culturing them in a culture tank and injecting them into a treatment plant. This method is to cultivate soil microorganisms under aerobic conditions, which cultivates soil microorganisms only in the growth and spore relationship, so that the number of spore sludges is small and the purification ability is not exerted. In addition, the treatment conditions in the treatment plant could not be completely treated as the soil microorganism treatment mechanism and the aerobic microorganism treatment function combined with the activated sludge process were maintained.

Prior arts related to this technology include Korean Patent Application Nos. 99-24285, 97-22715, 97-46746, 98-37732, 99-1147, 99-9977, and 99- 8048, 99-12013, 99-18203, and the like.

On the other hand, the limitations and problems of the prior art described above are the impossibility of perfect deodorization, deterioration of treatment efficiency of nutrients nitrogen and phosphorus, incapacity of reprocessing of the treated water, inherent limitation of the use of sludge compost, use of aeration tanks in multiple stages and volume of aeration tanks. This has been a problem, such as an increase in the power ratio due to the increase and unnecessary aeration.

The method does not fully apply the erosion mechanism, ie the principle of the erosion reaction, and the adsorption, decomposition, coagulation, macromolecularization and related corrosion of organic matter through the growth and spores of soil microorganisms and germination and cell growth. The reaction with precursors, and silicates and silicate degrading microorganisms, also does not apply the stage of corrosion that proceeds in the presence of them, but only metabolites, which are secreted by the soil microbial group for their survival in an empty nutrient state (phenol). It focuses only on aggregation, macromolecularization, and polymerization by the physicochemical properties of the group) or phenolic exposure group (phenolic exposure group), and it is considered that the method is limited by neglecting the corrosion reaction of soil microorganisms.

In addition, a method of cultivating Bacillus bacteria and treating sewage and wastewater is known. This is a method of treating Bacillus bacteria among selected soil species and proliferating selected dominant species and introducing them into the treatment plant. The treatment efficiency of organic matter, nitrogen, and phosphorus is generally good by applying spore and germination relations well, but the size of the aeration tank is large and several stages are needed. By neglecting this, it has been limited to complete odor removal, pathogen removal, reuse of treated water and recycling of sludge.

In the present invention, based on the recognition of sewage, sewage and wastewater resources, in the flocculation soil technology using the corrosive mechanism, by constructing an incubator and treatment system to continuously maintain accurate soiling reaction, organic materials, nitrogen Removes phosphorus, removes odors and odorless treatment plants.The treated water contains bioactive substances, growth accelerators, and antibiotics, and is reused for agricultural water, heavy water, and other purposes.The sludge removes pathogens and odors to prevent corruption. Advanced stabilization and reprocessing of the treated materials, which make it possible to reclaim resources such as various sludges and wastewater sludge, landfill site, and odor removal, soil reclaiming agent, soil reforming agent, and compost. The present invention was completed based on this.

Therefore, the object of the present invention is to recognize that sewage, wastewater and wastewater is also an important resource, by applying a corrosion reaction using soil microbial group, and the advanced treatment of sewage, wastewater and the resulting treated water and sludge It is to provide an advanced treatment process of waste and wastewater by the corrosive reaction that can be recycled.

The advanced treatment process of the waste water by the corrosion reaction of the present invention to achieve the above object is introduced into the flow control tank, and the concentrated supernatant is conveyed through the return pipe to remove odor and antagonize pathogens. Inflow screen tank; Active silicate is added in an amount of 100 to 500 mg / l per influent BOD equivalent introduced from the screen bath, and the dissolved oxygen concentration is maintained around 1.0 mg / l, and the precipitated sludge is returned through the return pipe (conveyance rate 50 to 100%). ) Flow rate adjusting tank; A non-aerobic tank for macromolecularization and polymerization of the influent through the flow adjusting tank at a dissolved oxygen concentration of 0 to 0.1 mg / l, a temperature of 4 to 45 ° C, a pH of 6 to 8, and an MLSS of 5000 to 8000 mg / l; The treated water introduced from the non-aerobic tank was operated at a dissolved oxygen concentration of 0.1 to 0.5 mg / l, a temperature of 4 to 45 ° C., a pH of 6 to 8, and a MLSS of 5000 to 10,000 mg / l to polymerize (corrosive precursor phase) and corrosion.

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

1 is a block diagram schematically showing a system for treating wastewater according to the present invention, wherein the treatment process of the present invention is roughly divided into a culture system and a treatment system.

Referring to Figure 1, the culture system is a process corresponding to the rear end in Figure 1, the concentrated sludge was carried out in the incubator in the incubator → spores → germination → cell growth of soil microorganisms in the incubator and then uniformly for 24 hours It is a system to return to the non-aerobic tank of the treatment plant, which is characterized by cultivating concentrated sludge rather than culturing sedimentary sludge. And will maximize the purification ability. In the present invention, an unexpired or anaerobic state means a condition that is not a complete aerobic or anaerobic state but is close to a normal aerobic or anaerobic state.

On the other hand, the treatment system is a process corresponding to the front end in Figure 1 basically carried out as a screen tank → flow control tank → un-anaerobic tank or micro-aerobic tank → micro-hog tank or un-anaerobic tank → sedimentation tank, part of the sedimentation sludge is returned to the flow adjustment tank and the rest The settling sludge is sent to a thickening tank.

The characteristics of this system are unreturned tanks or un anaerobic tanks, that is, conveyed from the rear end to un-anaerobic tanks or un- anaerobic tanks, that is, the front end, additives are introduced into the flow regulating tank, and the supernatant of the condensing tank is returned to the screen tank. Depending on the nature of the pollutant and the type of pollutant to be treated, adjustments can be made to vary the treatment function. This is solved simply by converting the US anaerobic tank into the US steam tank and simultaneously converting the US steam chamber into the US steam chamber. In addition, when the flow rate is so severe that it is subject to fluctuations and impact loads, it is a great feature to achieve stable treatment efficiency by converting both sets into an unfavorable state.

Influent flows first through the screen tank, while excess solids are filtered through the screen and immediately flow into the flow control tank. At this time, the supernatant from the sludge concentration tank is introduced at the same time, and this concentrated supernatant has an effect of eliminating odors of the influent and eradicating flies and pathogens due to the progress of corrosion.

In the case of screen baths, Hydrasieve screens are preferably used. The flow rate adjusting tank plays a role of preventing corruption and equalizing the flow rate, and the return of the settling sludge (50 to 100%) and additives are added thereto. Operational conditions are carried out in aerobic conditions at around 1.0 mg / l of dissolved oxygen concentration, and aeration and agitation are performed at the same time, but it is preferable to install underwater aeration equipment at the bottom to reduce power costs and increase oxygen efficiency. Raw water introduced into the flow control tank is an organic substance in the initial state that does not decompose, and is subjected to fermentation decomposition by microorganisms from the easily decomposed portion. This fermentation decomposition is an initiation stage of decomposition and plays an important role as a preliminary step for the next corrosion reaction, so that anaerobic decomposition such as rot fermentation affects the corrosive reaction, so the dissolved oxygen concentration is around 1.0 mg / l. Maintaining and decomposing in advance in aerobic conditions is a very important point.

In addition, an additive of active silicate is added to the flow control tank, because the corrosive process is necessarily polymerized and corroded under the action of soil microorganisms in the presence of silicate, and the input rate is 100 per inflow BOD equivalent. 500 mg / l is preferred. More specifically, the decay of organic matter is caused by the presence of silicates, which play a major role in the induction of metabolic and metabolic functions of soil microorganisms, and aromatic components are formed and polymerized under anaerobic conditions. It is corroded as a substance.

In the flow control tank, the raw water and the corrosive process progress, and the return sludge of the sedimentation tank containing the soil anaerobic microorganism and the soil aerobic microorganism reacts. Odor is eliminated and 30% pre-organic removal efficiency is also achieved.

Next, the flow control tank is introduced into the non-anaerobic tank. The operating conditions of this tank are 0 to 0.1 mg / l of dissolved oxygen, temperature of 4 to 45 ° C, pH of 6 to 8, and MLSS vary depending on the inflow load. High concentrations of 8000 mg / l are performed.

As such, the method of placing the non-anaerobic tank after the flow regulating tank is one of the characteristics of the present invention. The most important thing to consider in the water treatment process using the corrosion reaction is the anaerobic microorganism with a slow growth rate. It is noted that it is a bacterial group that starts anger.

Therefore, an anaerobic tank was installed so that a group of anaerobic microorganisms centered on a group of bacteria decomposing silicate could proliferate well, thereby inducing a erosion reaction at the rear end at the peak. More specifically, the environmental purification activities of the early stages of corrosiveness are carried out in the anaerobic state, depending on whether or not proliferation of silicate-degrading bacteria, a kind of organized anaerobic microorganisms, may lead to decay of fermentation (low molecular weight). It is an important hump to go to Tue).

These silicate degrading bacteria include Bacillus mucijaginosus , Bacterium caldotyticus , Proteus milabilis , and the silicon, phosphorus and various Using minerals as raw materials, nitrogen and phosphorus are fixed and synthesized into their own organic matter.

The influent, which has passed through the anaerobic tank, enters the next stage, the Miho vessel, and all reactions and removal mechanisms are concentrated in this Miho vessel. Operation conditions are high concentration operation of dissolved oxygen concentration 0.1-0.5 mg / l, temperature 4-45 degreeC, pH 6-8, and MLSS 5000-10000 mg / l. In particular, aeration is an intermittent aeration method is preferable because the growth of soil microbial group mainly anaerobic conditions. Corrosion mechanism in water treatment is a technique to reproduce the cleaning function by the decay of organic matter occurring in the natural soil in the waste water under a certain condition. Therefore, the microorganisms in the Mihogi group where this technique is intensively shown can be said to be complex bacteria of soil aerobic and anaerobic microorganisms with the expression of aromatic constitutive metabolism.

Incoming organics, ie insoluble BODs, are oxidized by soil microbial populations as degradable BODs under these operating conditions. In other words, sugar is glucose, lipid is organic acid, uric acid is ammonia, protein is oxidized to H ₂ S through amano acid and synthesized by cell growth.

The remaining dissolved organics and ionic substances are then bound, granulated, and polymerized by sticky phenolic groups or phenolic exposure groups, which secrete soil microorganisms as a means of survival in an empty nutrient state. Molecularization, that is, polymerized (corrosion precursor), and in addition to the odor-causing ionic material, TN, TP is also efficiently removed, the polycondensation and corrosion in the presence of silicate gradually.

Describing the odor removal and the killing of various pathogens during this removal mechanism, the dissolved odorous substance is immediately combined with or adsorbed to corrosive precursors and microbial metabolites and removed from the liquid phase. Is used. On the other hand, E. coli, rot group, Staphylococcus aureus, etc. are sterilized by metabolites such as phenol group, phenol exposure group, and corrosion precursors, and also oxidizes perishable substances such as ammonia, amine, and scitol which are harmful to living bodies. Specifically, an enzyme such as urease which generates basic odor is inactivated, and an acid odor H ₂ S, a neutral odor methyl methyl captan and the like are oxidized and deodorized.

In addition, chelation is iron, aluminum, manganese, and other elements and corrosive substances to be internalized (chelating), which is characteristic of soil reaction, and this internalized material has excellent catalysis and deodorization effect. Metal ions, such as aluminum, are eluted from the filler of the corrosive sludge culture tank.

In the present invention, the micro-aerobic bath is operated at 0.1 to 0.5 mg / l of dissolved oxygen as an intermittent aeration method, and alternately performs aeration 60 minutes and stirring 60 minutes. In addition, by maintaining the highest dissolved oxygen concentration of 0.5mg / l, nitrifying microorganisms such as nitrosomonas (nitrosomonas europaea) genus and nitrobacter (nitrobacter winogradsky) genus that can grow at 1mg / l or more is suppressed In the absence of nitrification, it is removed in the ammonia nitrogen state as described above, and phosphorus is also maximally fed by soil microorganisms in the vicinity of 0.5 mg / l, and macromolecules and polymerized in the vicinity of 0.1 mg / l. In the sedimentation tank of

In addition, by completely recycling the contaminants such as organic matter, nitrogen, phosphorus, etc., which are not returned by internal conveyance from the unexplored tank to the untreated anaerobic tank of the front end, the return rate of the treated water is effective at about 100%.

A feature of the present invention is that it consists of a system (Switch) that can be switched over in the process of processing the anaerobic and microaerobic. In other words, the first configuration is the case of converting the non-aerobic tank of the front end into the un-analog tank. This is a combination of two micro-aerobic vessels, and it is preferable to recycle the treated water as agricultural water or plant growth accelerator and to compost concentrated sludge by treating only the corrosive precursor stage rather than realizing the needlessly advanced corrosion.

The second constitution is the case where the front end is converted into an aerobic tank and the rear end is converted into an anaerobic tank, which is effective for treating inflows having high nitrogen concentration but low phosphorus concentration, ie, nitrogen removal, and the treated water is bioactive water or heavy water. It can be reused as a system, and the concentrated sludge is effective for soil improving agent, soil reclaiming agent or early stabilizer or deodorant of landfill.

As a third configuration, the front end is the case where the rear end of the non-anaerobic tank is converted into the untied tank. Its application is effective in treating the case where the inflow water with low nitrogen concentration but high phosphorus concentration, ie, phosphorus removal is the main point, and the reuse effect of treated water and concentrated sludge is the same as the second. However, neither of these two tanks will be converted to non-aerobic tanks.

And the first, second, and third system is solved simply by switching the aquatic equipment at the bottom of the tank into aeration and agitation as needed, and must be returned (100%) to the shear tank in the forging.

Next is the sedimentation tank, where the polymerized or corroded influent is solid-liquid separated at the front end, and the treated water is discharged or reused, and the sedimentation sludge is returned to the flow control tank (50-100%), and some sedimentation sludge is sent to the concentration tank. do. Solid-liquid separation in the sedimentation tank has a high sedimentation rate and good interfacial separation, and the treated water has no smell because pathogens are killed and do not rot, and it contains bioactive substances, growth promoting substances, and antibiotics. When it reflects on, it has a characteristic that shines. More specifically, the bioactive substance is a vitamin, which is a product of soil microorganisms, for example, vitamin B ₁₂ and riboflavin produced by yeast and basidiomycetes in addition to thiamine, nicotinic acid, pyritokicin, and non-ion produced by Pseudomonas genus. , Pantodene, paraaminobenzolic acid, and the like.

Growth promoters are hormones. For example, azocin produced by Azotobacter promotes the growth and pruning of roots, and Gibberella produces gibbererlin to grow and bloom plants. The cytokinin produced by Agrobacterium is a hormone that promotes cell division and kidneys. As such, hepatocytes produced by actinomycetes and higher fungi in phenolic metabolites of soil microorganisms, siberins produced by filamentous fungi, yeasts of the genus Tolula , and mycotorlula , etc. Formic acid, crude acid, propionic acid, aspartic acid, and hurricane produced by microorganisms have plant growth promoting functions. In addition, soil microorganisms release antibiotic metabolites to have antimicrobial properties in addition to their species, and actinomycetes are overwhelming as microorganisms, and nocadia , ammonia and pectin, which degrade cellulose as actinomycetes among soil microorganisms. micro for decomposing Streptomyces mouses (Streptomyces), chitin (chitin) to decompose (Pectin) all bonus Fora (Micromononaspora) etc., and the kind of the antibiotic to the soil microbes creates streptomycin, port non-cephalosporin, penicillin, Oreo Mycin, teramicin and the like.

In the next process, sludge from the settling tank is introduced into the thickening tank, concentrated, and then, some are incubated with soil microorganisms in the culture tank, and some are dehydrated as surplus sludge and reused.

In addition, the supernatant of the concentration tank is returned to the screen tank, which is the first introduction of the whole quantity processing system system, thereby eliminating the odor of the screen tank, pre- eradication of pathogens including flies and mosquitoes, and contributing to the implementation of a sanitary and odorless treatment plant. This is because the concentrated equivalent water is a product that has undergone corrosion and thus has an odor removal and insecticidal effect.

Corrosion sludge culture tank has a function of inducing concentrated concentrated sludge into soil microorganisms, and the necessity of this is rapidly incubated by incubating the high concentration of soil microorganisms in advance and entering the non-aerobic tank (shear) as the main process. To achieve the soil corrosion reaction, such sludge culture operation is a big difference that can not be seen in low molecular oxidation treatment such as standard activated sludge method.

The interior of the corrosion culture tank contains solid biocatalyst fillers with high density of microorganisms with phenolic metabolic functions and high metabolite concentrations, that is, solid biocatalyst fillers that solidify humus soil, peat, and peat, and highly unstable silicates. There is a solid filling part containing filler, the middle part of which there is a gap, and the size of the gap is about 1/5 of the diameter of the solid filling part. The bottom of the corrosion culture tank has aeration aeration and aeration, which can perform agitation, the top has a vent nozzle (Vent Nozzle) that can maintain the inside of the tank closed and open (Open).

The culture operation conditions are, for example, in the first unexpired state, that is, the dissolved oxygen concentration of 0.1 to 0.5 mg / l, the reaction time of 11 hours and 30 minutes, and the MLSS of 7000 to 10000 mg / l and the pH of 6 to 8 Proliferate spores of microbial populations. Thereafter, after being stopped for about 30 minutes, the second anaerobic state, that is, dissolved oxygen concentration 0.1 mg / l or less, reaction time 11 hours and 30 minutes, MLSS was operated at 7000 to 11000 mg / l and pH 6 to 8 By germinating soil microbial group, and cell growth.

The non-aerobic operation is carried out in a sealed state by using an upper vent nozzle, and the microbial sludge having high cell count at a high concentration transfers 1/2 of the culture tank to the storage tank for the next 30 minutes of rest period. In the storage tank, aeration is carried out, and half of the tank capacity is returned to the non-aerobic tank (shear) evenly throughout the day to perform the corrosion reaction. The more complete corrosion reaction is achieved by repeating the circulating cultured sludge, ie, the process of circulating the soil microbial group into the treatment system.

Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to FIG. 2.

Inflow water, such as sewage and waste water, is introduced into the flow regulating tank 2 via the screen tank 1. At the inlet of the screen tank 1, the concentrated supernatant is introduced through the conveying pipe 61 to remove odors and antagonize pathogens, thereby implementing a sanitary and odorless treatment plant. Active silicate is added to the flow rate adjusting tank 2 as the additive 9, and the input rate is 100 to 500 mg / l per inflow BOD equivalent. In order to maintain and equalize the dissolved oxygen concentration of 1.0mg / l in the tank and install the underwater aeration apparatus (10). The additive 9 serves to carry out precorrosion and thus lead to an effective organic corrosion reaction. In addition, the settling sludge is conveyed through the conveying pipe 51 and the conveying rate is 50 to 100%. This precorrosive reaction achieves an organic removal efficiency of about 30% and results in an odorless treatment plant.

The outflow water of the flow rate adjusting tank 2 is introduced into the non-anaerobic tank 3 through the flow rate adjusting tank outlet pipe 21. The operating conditions of the non-aerobic tank 3 are 0 to 0.1 mg / l of dissolved oxygen concentration, 4 to 45 ° C in temperature, 6 to 8 in pH, and 5000 to 8000 mg / l in MLSS. The condition of the non-anaerobic tank (3) is to allow the group of anaerobic microorganisms, which are silicate decomposing bacteria, to proliferate so that the treatment system can be induced to a corrosive (polymerization) system without flowing into a corrupt fermentation (low molecular weight) system. The underwater aeration apparatus 11 is installed in the bottom of the non-aerobic tank 3, and it operates to meet this condition. In addition, the treated water is returned through the return pipe 41 in the Miho key 4, which is a forging step.

The influent is introduced into the micro-explosion tank 4 after the treatment of the non-analysis tank 3. The operating conditions of the micro-fuge tank 4 are 0.1 to 0.5 mg / l of dissolved oxygen concentration, 4 to 45 ° C in temperature, 6 to 8 in pH, and 5000 to 10000 mg / l in MLSS. The aeration method is also intermittently aeration through the underwater aeration machine 12 installed in the bottom, for example, aeration 60 minutes, stirring 60 minutes alternately. The dissolved oxygen concentration is 0.5mg / l for oxidation of insoluble BOD, growth of microorganisms and synthesis of organic nitrogen and phosphorus. In other words, organic matter oxidation, proliferation and coagulation polymerization by soil microbial groups begin. At a dissolved oxygen concentration of 0.1 mg / l, dissolved BOD, ionic substances, and malodorous substances are polymerized and condensed by phenol groups or phenol exposure groups produced by soil microorganisms, and macromolecules and polymerization are performed by chelating reactions. Corrosion precursor stage). At this time, non-phenolic fungi such as Escherichia coli, Staphylococcus aureus, Salmonella, etc. were killed by antibiotics in the metabolites, and the remaining odorous substances and ionic substances were removed by chelation (internalization) reaction, and microbial food was fed. do. In this way, organic matter, nitrogen, phosphorus, odor, decay bacteria, etc. are effectively removed under changing oxygen conditions caused by intermittent aeration, and in particular, the reaction time until the corrosion precursor stage (polymerization) is very short. In addition, the treated water is returned from the unheated tank through the pipe 41 to the un anaerobic tank 3 at the front end, thereby further promoting the corrosion reaction. The conveyance rate at this time is operated at 100%. At this time, growth promoters, bioactive substances and antibiotics contained in the metabolites of soil microorganisms contribute to the recycling of treated water and sludge.

According to the present invention, in accordance with the purpose of regeneration of the influent to be treated in the execution of the connection between the non-aerobic tank (3) and the micro-exposure tank (4), the first method is to complete both the micro-anaerobic tank (3) and the micro-key (4). The second method is composed of Miho-gi and Mi- anaerobic tanks, and the third method is characterized by being able to be configured quickly as needed.

As described above, the first method serves the purpose of composting the treated water into agricultural water, plant growth accelerator, and sludge, and the second method is effective when the influent has high nitrogen concentration but not high phosphorus concentration. Biologically active water, heavy water systems, and reusable sludge are effective for soil improvers, soil stabilizers or early stabilizers and deodorants in landfills. The third method is effective in treating influent with low nitrogen but high phosphorus concentration. The use of sludge for recycling is the same as in the second method.

All three methods must return 100% of the treated water from the unexploded tank (4) to the anaerobic tank (3), and the underwater aerators 11 and 12 selectively perform the aeration or agitation required in each tank. . The outflow water of the micro-fuge tank 4 flows into the sedimentation tank 5 through the pipe 42 to separate solid-liquid, and the treated water is discharged or recycled, and the sedimentation sludge is flow-through adjustment tank 2 through the return pipe 51. And some are sent to the concentration tank via the settling sludge outflow pipe (52). In the sedimentation tank 5, the sedimentation is surely performed rapidly to the extent that the interfacial separation is obvious, and the treated water has odor, sterilization, and stabilization progressed, and has a characteristic of shining shining when reflected by sunlight.

The sedimentation sludge introduced through the pipe 52 is concentrated in the thickening tank 6, and the concentrated sludge is introduced into the dehydrator through the surplus sludge discharge pipe 63 for dehydration and then recycled. Concentrated sludge has undergone corrosion, so no flocculant is required for dehydration. And the supernatant of the condensate tank is conveyed to the screen tank 1 of the first introduction portion of the influent water through the total condensed supernatant conveying pipe 61.

A portion of the concentrated sludge is introduced into the corrosion sludge culture tank (7) through the concentrated sludge outflow pipe (62), and then dominates into the soil microorganisms. The culture tank (7) has a solid filler (13) is located inside, the solid biocatalyst filler and the solid silicate filler is filled in the solid filler (13), there is a gap between the two fillers and the size of the gap Is about 1/5 of the solid-state filling unit 13, and the underwater explosion apparatus 14 is installed at the bottom.

Culture conditions of the cultured sludge culture tank (7) were soil oxygen concentration of 0.1 to 0.5 mg / l, reaction time of about 11 hours and 30 minutes, MLSS concentration of 7000 to 10000 mg / l, and pH of 6 to 8 After inducing spores and resting for about 30 minutes, the soil-based microorganisms were operated at a sealed oxygen concentration of 0.1 mg / l or less, reaction time of about 11 hours and 30 minutes, MLSS concentration of 7000 to 11000 mg / l, and pH 6 to 8. After induction of germination and cell proliferation of the group, the mice are rested for about 30 minutes. During this 30-minute rest period, 1/2 of the culture tank 7 is sent to the corrosion sludge storage tank 8 through the corrosion sludge outflow pipe 71. In the corrosion sludge storage tank (8), while aeration is carried out by using an air diffuser (15) at the bottom, the half amount of the storage tank (8) is corroded evenly for about 24 hours to the un anaerobic tank (3) through the return pipe (81). Return it.

In the present invention, the additive is added to the flow control tank and the aeration tank is divided into two groups. It is characterized by the fact that the introduced sludge of the culture tank is concentrated and conveyed, and the concentrated supernatant is returned to the first influent introduction part, and the treatment system is configured from the original treatment to the recycling of treated water and sludge. Can be achieved by the present invention.

As a spreading effect of the present invention, first, the sewage and sewage treatment plant itself has a large volume load, and in particular, even high concentration treatment does not require dilution, has a small area, requires little investment, and does not require a coagulant. Resistant to impact loads, power consumption and operation and management costs are reduced by 30% of the existing activated sludge method, and the existing treatment plant can be easily retrofitted, and no extinguishing tank, disinfection tank, scum removal device, or separate deodorizer are needed. The realization of the treatment plant has the effect of improving the health and hygienic working environment of workers.

In addition, it is able to effectively remove nitrogen and phosphorus, nutrients that are the rust and red tide sources of the organic ecosystem and the discharge stream ecosystem, and the treated water is corroded to kill rot pathogens such as Escherichia coli and remove odors. It does not decay even if left unattended, but rather contains bioactive substances, sex promoting substances, and antibiotics. When discharged, it is possible to improve the purification capacity of river ecosystems, recycle water into agricultural water, heavy water, biologically active water, and other reused waters. It has the effect of being zero.

In addition, the surplus sludge of the condensate tank is used for various sewage, sewage sludge from wastewater and wastewater treatment plant, and fertilizer of raw waste, and dehydrated cakes contribute to deodorization and early stabilization when used as soil cover agent, soil improver, and landfill agent. If it does, it does not need a separate fermentation process, and there is no secondary pollution after soil reduction, and it is valuable as a soil environmental restoration agent because it has the effect of enhancing soil intellect, nutrient supply source of soil microorganisms, and acid soil improvement.

In addition, most domestic and foreign sewage and sewage and wastewater treatment plants that use biological sludge oxidation (low molecular weight) treatment by the activated sludge method and its modifications (advanced treatment) inevitably release CO ₂ , CH ₄ , and N ₂ gas into the atmosphere during the treatment process. This adds to the global warming phenomenon. Atmospheric greenhouse effect (warming potential) is ₂ to 30 times for CH _{4 and} 200 to 300 times for N ₂ O when CO ₂ is 1, which reduces air pollution by 2 This is a dysfunction caused by a car, and it is a time when control measures are extremely required. However, the present invention effectively removes nitrogen and phosphorus and stabilizes by polymerizing and corroding without denitrification or anaerobic digestion, so it does not release CH ₄ , N ₂ gas into the atmosphere, thus acting as a net function of global warming. There is another great effect.
