The digester ④ serves to decompose anaerobic organic matter through digestion to reduce the content of organic matter in concentrated culture sludge and to stabilize and remove odors.

Therefore, the introduction of the second concentrator ⑥ and the digester ④ is selected according to the inflow of sewage and organic wastewater (livestock wastewater, manure, etc.) or the type of contaminant to increase the odor removal efficiency to produce a more stable dehydrated cake. .

1 and 2 in the first and second embodiments

The biological reaction tank ② and the culture tank ⑤ is a high biological treatment means of various patents by the applicant of the present invention, including Patent No. 0487582 (April 26, 2005) [Sludge treatment apparatus and treatment method of sewage or organic wastewater] It is desirable to apply the technology based on it.

In the bioreactor ②, the culture tank ⑤, the sludge mixing tank ⑭ and the digestion tank ④, it is preferable that various well-known acid engines are arranged in connection with the blower (B) for aerobic conditions and agitation.

The post-treatment means is a liquid such as discharged water, various symbolic waters, a dehydration filtrate, that is, discharged water from secondary sedimentation battery ③ in FIGS. 1 to 4, digestion symbol collection in an anaerobic digester ④, concentration in concentrator ⑥ Deodorization treatment of supernatant water, dehydration filtrate in dehydrator ⑦, filter filtrate in filter ⑨ and sterilizer 이나, or gas collected in bioreactor ② or culture tank ⑤ to create a more pleasant and hygienic wastewater treatment facility environment and aversive facility It is preferable to introduce ultraviolet ray treatment means (ultraviolet rays lamp) for recognition ignorance.

The culture tank ⑤ is equipped with a terrestrial or fertilizer type incubator to create the same environmental conditions as the soil for the microorganisms for cultivation and propagation to remove odorous substances generated from the sludge and stabilize and stabilize the sludge.

Filler is filled in the incubator provided in the culture tank ⑤ used in the present invention,

This fill consists of soil, humus, sludge crystals treated by soil microbial action, and consists of pellets compressed into irregular masses, cylinders, spheres, etc., and pumice of siliceous, zeolite or elvanite systems.

The filling in the incubator functions to make the soil microorganisms create the same environmental conditions as the natural soil,

Soil microorganisms cultured and propagated in this process are predominantly Bacillus, Thiobacillus, Pseudomonas, Micrococcus, Acinetobacter, Aeromonas, etc. do.

Since the sludge treated by the present invention has good separability with water and is excellent in dehydration, the amount of flocculant added during dehydration is good even if the amount of the flocculant is reduced or not added.

In particular, organic matters (organic aqueous solutions and water-soluble organic mixtures) are rapidly bound, granulated, aggregated, condensed, and polymerized by adding microbial metabolites including phenol and compounds having phenol exposure groups, and macromolecules. We become angry, mass product.

If an appropriate amount of a substance having a large amount of activated silicic acid is added thereto, it causes a polycondensation reaction for corrosion, so the sedimentation property is quite excellent and the treatment efficiency is very high.

When concentrated in a concentration tank in a general treatment plant, the water content drops from 99.2% to 97%,

In the present invention, the sedimentability is quite good from 99.2% to 95%, and the produced sludge does not cause odor because corruption does not occur because of condensation polymerization and polymerization instead of oxidation, catalysis, assimilation and decomposition processes.

In addition, dehydrated sludge has an increased content of phosphorus and nitrogen, so it can be used as a soil modifier when dried, and it is possible to reduce the soil for the purpose of enhancing the intellect of soil and feeding of microorganisms.

Even when incinerated, fuel costs are reduced by the difference in water content, thereby preventing degradation of incineration efficiency due to organic polymer flocculant.

In order to maintain the above-mentioned state of communication in the culture tank (5), a conventional air blower blows air into the culture tank with a conventional blower, and a conventional acid machine for dispersing air introduced through the blower is installed in the culture tank.

In addition, when the oxygen consumption rate of the introduced sludge is lowered, the dissolved oxygen concentration becomes too high, so that the operation of the blower is inevitable in order to maintain the above-mentioned state.

In order to prevent solid-liquid separation due to sludge settling in the culture tank, an agitator for stirring the inside of the culture tank is preferably installed.

The pH in the culture tank ⑤ is preferably pH 6-8, which is a normal biological treatment condition, the time for the sludge stay in the culture tank is 1.5 to 2 days,

Originally, microorganisms generally have antimicrobial properties against microorganisms other than their own.

In particular, through the excretion of the antimicrobial microbial metabolite, the antimicrobial activity against microorganisms other than the species, and the antimicrobial activity against microorganisms other than the soil bacterial group is most remarkably active.

Antibiotics such as Penicillin, Streptomycin, Loygomycin, etc. are cultured by using microorganisms.

Antimicrobial activity as a total microorganism that coexists with soil flora such as human beings on earth is not wide.

Therefore, the antimicrobial properties of this soil bacterium are very broad, and it is the same context that all higher animals have antimicrobial properties.

This antimicrobial effect can reduce the amount of disinfectant used.

Since the present invention is to cultivate a group of soil microorganisms, it is not necessary to use a seed agent at all, and the amount of chemicals can be reduced here.

The concentrated culture sludge dewatering cake produced through the wastewater odor treatment apparatus using the concentrated culture sludge cake according to the present invention is decomposed and synthesized by the action of microorganisms in which organic substances such as carcasses and carcasses exist in the soil. Brown or dark brown amorphous polymer material produced by polycondensation), which gives a smell like ordinary soil and removes odor causing substances.
