TREATMENT METHOD FOR ORGANIC WASTE FLUID AND TREATMENT APPARATUS THEREFOR

摘要

PROBLEM TO BE SOLVED: To enhance the solubility of sludge efficiently, to accelerate the generation of a digestion gas and to reduce the amount of sludge to be disposed of in the anaerobic treatment of an organic waste fluid.

SOLUTION: A solid component in the inflow organic waste fluid is dispersed and an organic substance in the organic waste fluid after dispersion is modified. The organic waste fluid after modification is introduced into an anaerobic digestion tank to perform anaerobic digestion. The digested sludge in the anaerobic digestion tank may be drawn out and subjected to dispersion and modification treatment to be returned to the anaerobic digestion tank. The solid-liquid separation of the drawn-out digested sludge is performed and the obtained separated sludge may be subjected to dispersion and modification treatment.
