METHOD OF SOLUBILIZATION OF METHANE FERMENTATION RESIDUE, METHOD OF TREATMENT OF ORGANIC WASTE, AND APPARATUS FOR ORGANIC WASTE TREATMENT

摘要

PROBLEM TO BE SOLVED: To provide a method for solubilizing methane fermentation residue by which the residue left insoluble by methane fermentation can be solubilized, a method of treatment of the organic waste by which the quantity of the residue is reduced more as compared to conventional methane fermentation processes and an apparatus for the treatment.

SOLUTION: The method of treatment of the organic waste includes a step in which the organic waste is subjected to methane fermentation in a methane fermentation tank, a step in which the residue from the methane fermentation is solubilized by the treatment with aerobic bacteria and a mineral and a step in which the liquid component obtained by the solubilization is returned to the methane fermentation tank and is subjected again to methane fermentation.
