Large-scale biogas projects are impeded by single feedstock, relatively low gas production rate, backward equipment, and other technical bottlenecks in China. Due to the decentralized sources as well the complex components of feedstock in the southwestern region, a new mixed fermentation model of multiple raw materials needs to develop to improve biogas project anaerobic digestion efficiency. Herein a new pattern for utilizing biogas and fermentation residues based on co-digestion of urban decentralized feedstock by the continuous stirred tank reactor process was presented, to digest materials such as straw and raw manure. Results showed that 900 m3 biogas could be produced from 7.9 tons of pig manure, 8.2 tons of thick sewage, and 0.2 tons of crop stalks per day in the 600 m3 fermentation tank during 30 days stabilized operation, and the tank volume gas production rate was up to 1.5 m3/(m3∙d).
