Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a method and an apparatus for treating wastewater microbiologically.

[0002]

2. Description of the Related Art In the standard activated sludge method, which is a conventional wastewater treatment method using microorganisms, the precipitated bacterial bed (MLS) is used.
It is customary to return a part of S) to the aeration tank as activated sludge, withdraw the remaining sediment as excess sludge for dehydration, and then have the waste treatment company collect it for a fee.

[0003]

In the conventional standard activated sludge method, a large amount of excess sludge is generated, so a large-scale facility and labor costs associated with it are required for dehydration treatment, and the sludge after dehydration is required. There was also a problem in that a large amount of cost was incurred in collecting the sludge, and the sludge treatment cost accounted for 80% to 90% of the running cost. In addition, since it decomposes at the time of settling in the settling tank, it has a bad odor, not only does the person involved in the process feel distressed at the work, but also the bad odor drifts to the neighborhood, and there is a residential area around the treatment plant. Recently, there was a problem that complaints from neighboring residents were received. Further, if the decay in the settling tank exceeds a certain level, bulking occurs, and it is necessary to treat the whole decayed material by vacuuming and the like to treat it like the excess sludge, which is a problem. In addition, since the treated water is spoiled, Escherichia coli, germs, and pathogenic bacteria are generated, and if discharged as it is, it may damage the neighboring ecosystem and harm the health of living organisms including humans. There was a problem that chlorine had to be organically discharged and then it would be organically associated with various substances and adversely affect the environment. It should be noted that carbon dioxide, hydrogen sulfide, nitrogen oxides, and sulfur oxides are generated from the treatment plant, and even if only carbon dioxide is considered, the amount of carbon dioxide emitted by all of Japan is about 8 to 9
% Is generated at the wastewater treatment plant, which is one of the factors leading to global warming.

The present invention uses the complex fermentation method to stop the conventional spoilage in the aeration tank and the precipitation tank, to eliminate all aerobic and anaerobic Fusarium genus, and to cause solid fermentation in the precipitation tank. By doing so, the clear water and the precipitate are clearly separated, and the amount of the precipitate is reduced to about 1/5 to 1/10 of that of the standard activated sludge method, and a part of the precipitate is obtained. Circulate and recycle as a fungus bed to further reduce the amount of sediment, reduce excess sludge treatment costs, and eliminate odors by switching spoilage to fermentation,
Uses a microorganism that suppresses the generation of carbon dioxide, hydrogen sulfide, nitric oxide, and sulfur oxide, generates oxygen and negative ions, and suppresses the generation of bulking, and further suppresses Escherichia coli, miscellaneous bacteria, and pathogenic bacteria in discharged water. It is an object of the present invention to provide a method and a device for treating wastewater, and more specifically, a method and a device for treating a combined circulation type recycled bacterial bed combined fermentation wastewater.

It is configured to be returned to the co-fermentation tank, the first tank of a plurality of microorganism treatment tanks, or the next several tanks individually or simultaneously.

[0010] Similarly, in order to achieve the above object, a wastewater treatment apparatus using microorganisms according to claim 3 of the present invention ferments by introducing a predetermined enzyme solution which is a fermentation derivative that receives wastewater and promotes fermentation by microorganisms. The required number is determined because the fermentation tank that adjusts the flow rate of treated water and sends it out and the process of complex fermentation such as septic fermentation, fermentation, fermentation synthesis, and synthesis differ depending on the nature and components of the wastewater. A wastewater treatment apparatus comprising a plurality of microbial treatment tanks and a settling tank connected after the last of the plurality of microbial treatment tanks, wherein each of the microbial treatment tanks has a predetermined bacterium existing or expressed therein. It is configured such that the bacterial bed for supplying the water is added, and the air is supplied, and the treated water that has finished fermentation from the flow rate adjusting and fermenting tank is introduced into the first tank of the plurality of microorganism treating tanks to treat each microorganism.
