APPARATUS FOR CONVERTING ORGANIC WASTE INTO RESOURCE AND METHOD FOR CONVERTING ORGANIC WASTE INTO RESOURCE

摘要

PROBLEM TO BE SOLVED: To take potassium into a compost as much as possible. SOLUTION: An organic waste such as livestock excretion or others is separated into solid content and separated liquid by a solid-liquid separator 2. The separated liquid is biologically treated by water treating facility. Thereafter, potassium is separated as concentrated liquid from the separated liquid obtained by subjecting the organic waste to the solid-liquid separation by an potassium recovering apparatus 5 composed of a reverse osmosis membrane. And, this concentrated potassium liquid is sprayed through spray nozzles 31 onto the solid content being fermented in a fermenting tank 32 of the composting apparatus 3.
