Reduction and Biogas Production System Using Anaerobic Digestion of Organic Waste and Livestock manure and Operation Method Using the Same

摘要

The present invention relates to a system for reducing organic wastes and livestock manure by anaerobic digestion and producing biogas, and a method of operating the system. The system is capable of facilitating hydrolysis in an acid fermentation tank and methane fermentation in a methane fermentation tank, And to reduce the efficiency of livestock manure reduction, and to increase biogas production. To this end, the present invention relates to a system for reducing biomass production by applying anaerobic digestion to organic wastes and livestock manure, wherein the concentration of total solids in the organic wastes and livestock manure after pretreatment is less than 12% (100); An acid fermentation tank 200 for hydrolyzing organic wastes and organic substances contained in livestock manure by a tubular anaerobic microorganism that is a producing bacteria by applying a first anaerobic digestion process after the total solids concentration is controlled in the mixing equalization tank 100, Wow; A mixed gas storage tank 300 for storing a mixed gas generated during hydrolysis in the acid fermentation tank 200; A methane fermentation tank 400 for continuously decomposing and fermenting organic substances by an anaerobic microorganism, which is a methanogenic organism, by applying a second anaerobic digestion process to the organic waste hydrolyzed in the acid fermentation tank 200 and livestock manure; And a biogas reservoir 500 for storing biogas including methane gas, carbon dioxide, ammonia gas, and hydrogen sulfide generated in the methane fermentation process in the methane fermentation tank 400.
