Description of the Related Art Even with the technical progress of the activated sludge method which has been continuously developed, it is unavoidable to prevent the generation of odors, and it takes time for the filter membrane technology for adjusting the concentration of wastewater to spread. As for the improvement of sludge quality in the concentration tank, the current status is maintained. There are some cases in which ancient microorganisms and facultative anaerobic bacteria are made to produce metabolites and used for deodorization and purification of sewage. However, there are many problems such as unstable metabolite content. There is also an example in which soil containing fulvic acid is made into pellets, and sewage or sludge is contacted with this to deodorize or purify, but the amount and quality of elution is not constant, and the return sludge necessary for stabilizing the quality of the treated water is It also took a long time to generate, and there were problems such as too many unspecified factors.

It is an object to reduce sewage organic matter by oxidation and condensation, and at the same time, to deodorize and prevent an increase in the number of processes. In addition to the sludge thickening tank, another object of the present invention is to simultaneously activate the related microorganism group due to the biological activity which is another characteristic of the enzyme humus, and simultaneously improve the quality of the sludge that proceeds with it. ..

て発揮させるものである。The method for deodorizing and purifying sewage by humus according to the present invention is to remove an organic substance complex (corresponding to fulvic acid in the analytical classification) iron complex contained in an enzyme humus in an amount of 10% or more. The characteristics of iron materials are exerted on sewage organic matter.

This is due to active oxygen (hydroxyl radicals and the like) generated between the complex or excess divalent iron ion.

る。In the heterogeneous condensation, a condensate is formed from a protein, an amino acid, an organic acid and a saccharide in wastewater and a high molecular weight organic complex iron complex (organic complex having a molecular weight of 2000 or more).
Each condensate is condensed to become a sedimentable solid substance through the suspended particles.

て、アンモニア等の臭気の発生を根絶する。[0007] Also, oxidases inactivated by sulfides are activated together with excess iron ions to generate oxygen and hydrogen peroxide, and then active oxygen is generated. On the other hand, SH group enzymes (urease, etc.) are inactivated together with active oxygen to eliminate the generation of odors such as ammonia.

各構造中に取り込まれ、無臭化される。Of the odors generated, hydrogen sulfide, ammonia, methyl mercaptan, methyl sulfide and the like, which are easily oxidized, are oxidatively decomposed or polymerized to become non-volatile and deodorized, and normal butyric acid and isovaleric acid are hardly oxidized. , Various organic acids such as normal propionic acid, high molecular neutral odors such as dimethyl sulfide, are incorporated into each structure that has become a liquid giant macromolecule because many sedimentable solids or saccharides as condensate are bound, Deodorized.

When the solids are mixed, they are deodorized.

る。In the precipitation solidification, the deodorization reaction proceeds at the same time, but the reaction completion time is delayed. In particular, when highly unsaturated fatty acids having 18 or more carbon atoms are present in 20 ppm or more, it continues for 2 days and 100 ppm for 10 days. in the meantime,
Generation of active oxygen continues. Usually completed within 12 hours.

In addition to the above, microbial groups such as flocculent biopolymer-producing bacterial groups, protozoa, and dechambered bacteria are grown, and by using a concentration that maintains the micellar colloid, the bond between sludges is continuously increased and generated during the period. Oxygen and hydrogen peroxide prevent the growth of facultative anaerobic bacteria and anaerobic groups inside even with normal aeration, and produce sludge that is difficult to deteriorate and deteriorate. Since it has a strong structure, the adsorption of the surface, the occluding power and the dehydration property as a whole are improved.
