摘要： PROBLEM TO BE SOLVED: To provide methane fermentation method and system for organic solid waste which can stably maintain efficient methane fermentation even if scale up is caused.
SOLUTION: Organic solid waste C is anaerobically stored in a raw material tank 10, a decomposing microorganism-containing fermented solution S of waste is stored in an anaerobic fermentation tank 30 communicating with the raw material tank and vapor phase parts, the fermented solution in the fermentation tank is continuously fed to the raw material tank, the waste is immersed therein, the mixed solution of the waste in the raw material tank and the fermented solution, C+S is continuously extracted into a solid-liquid separation device 20 so as to be separated into a solid content E and a filtrate D, also, the separated filtrate is fed to the fermentation tank, further, the solid content is returned to the raw material tank, the waste in the raw material tank is decomposed while being immersed into the fermented solution circulating among the raw material tank, the solid-liquid separation device and the fermentation tank, and decomposed product gas G is recovered from the vapor phase parts of both the tanks 30, 10. Preferably, the feed amount of the fermented solution or the extraction amount of the mixed solution is adjusted in accordance with the separation amount of the filtrate in the separation device.
