Wastewater treatment method and wastewater treatment facility by aeration and fermentation decomposition

摘要

PROBLEM TO BE SOLVED: To solve the problems in dealing with environmental conservation as the treatment and disposal of the organic sludge discharged as excess sludge, etc., and associated themes in the conventional waste water treatment (activated sludge method). SOLUTION: The organic matter in the waste water to be treated is segmented and incorporated respectively into sewage and mud water by the characteristics thereof. The organic matter in the sewage is subjected to aeration decomposition treatment and the organic matter in the mud water to fermentation decomposition treatment, by which the entire amount organic matter included in the waste water to be treated is made into the object for the decomposition treatment. The integral and parallel implementation of the cleaning and composting of the waste water to be treated is eventually made possible, by which the simultaneous and integral solution of the problems of the treatment and disposal of the sludge in the conventional method and the problems relating to the environmental conservation is thus made possible.
