PURPOSE: A biogas production system for integrated organic waste is provided to be able to effectively process solid phase organic waste with relatively low moisture content, wet organic waste with relatively high moisture content, and mixed organic waste mixed with two types of organic waste, and to hydrolyze organic waste with relatively low moisture content by cyclic supply of anaerobic digestion liquid. CONSTITUTION: A biogas production system of integrated organic waste comprises a first reservoir, a second reservoir, a filter(30), a solid-liquid separator, a high-index anaerobic digestion tub, and a gas reservoir. The first reservoir stores first organic waste having moisture content more than a predetermined standard. The second reservoir stores second organic waste having moisture content less than a predetermined standard. The filter comprises a case(31), an exhaust frame(32) of mash form, and a filter stage(33). The exhaust frame of mash form divides the inside of the case into top and bottom. The filter stage absorbs the first and second organic waste introduced into the case to process the hydrolysis, and is supported by the exhaust frame. The solid-liquid separator separates soluble organic compounds hydrolyzed in the filter to solid and liquid. The high-index anaerobic digestion tub ferments the hydrolysate liquid separated from solid with methane, separates biogas (methane gas) from anaerobic digestion liquid, and transfers the anaerobic digestion liquid to the filter so that the anaerobic digestion liquid is absorbed into the filter stage. The gas reservoir stores the biogas. [Reference numerals] (AA) Organic waste; (BB) Upper layer part; (CC) Lower layer part; |
