BIOLOGICAL TREATMENT METHOD OF SOLID ORGANIC SUBSTANCE

PROBLEM TO BE SOLVED: To provide a biological treatment method of solid organic substances which does not leave any residues ultimately left so as solve a problem in a conventional technique that since residues are left after reaction in treatment of organic wastes, which are living life residues of human being, the residues have to be treated further. SOLUTION: In a method for treating solid organic substances containing low active components and high active components to microorganism decomposition reaction by microorganism, the total amount of undecomposed reaction residues 2, which are the low active components, left after the batch decomposition reaction of organic mixed substances, which are raw materials, one time in a batch reaction system 1 are mixed with the substance 3 treated in the next batch operation and the mixture is subjected to the decomposition reaction in the same batch reaction system 1 and this operation is successively repeated in every batch operation, so that the undecomposed reaction residues are practically not generated in the outside of the batch reaction system.
