The preparation of biogas by adopting an anaerobic fermentation technology is a mainstream process for disposing organic wastes (such as livestock and poultry manure and the like). At present, the domestic large-scale biogas engineering mainly takes a medium-temperature (38 ℃) continuous wet anaerobic fermentation process as a main part. According to the differences of sources, types, properties and the like of biomass raw materials, the medium-temperature wet anaerobic fermentation process is different and mainly reflected in the aspects of the structure, the process flow and the like of an anaerobic fermentation reactor. The concentration of the feedstock is a key factor affecting the choice of anaerobic fermentation reactor. When the concentration of the raw material is low (the solid content is 3% -5%), an up-flow sludge bed reactor (UASB) is usually adopted; when the concentration of the raw material is high (such as 8% -12%) a complete mixed anaerobic reactor (CSTR) or a mixed plug flow anaerobic reactor (HCPF) is usually used.
At present, livestock and poultry breeding enterprises have various manure cleaning modes, dry manure cleaning, water-soaked manure and water-washed manure are common, and different manure cleaning modes cause large concentration difference of manure raw materials, so that great difficulty is caused to large-scale biogas engineering operated by a regional third party.
