Agricultural rural waste in China has large output, various types and complex components. Anaerobic fermentation is an important way for producing renewable energy biogas by utilizing agricultural wastes, and mainly comprises wet anaerobic fermentation and dry anaerobic fermentation. The traditional wet anaerobic fermentation has large water consumption, can also produce a large amount of biogas slurry, and has low utilization rate of the biogas slurry, and secondary pollution can be caused by improper treatment. With the gradual adoption of the dry manure cleaning process in large-scale farms in China, the yield of solid manure is increased, and the development of dry anaerobic fermentation technology in China is promoted. But the dry fermentation material has high solid content, and the problems of slow degradation rate of the substrate, low mass and heat transfer efficiency and the like exist, so that the utilization rate of the fermentation residues is low. Anaerobic fermentation usually shows a good gas production effect under medium-high temperature conditions, so additional heat preservation measures are needed, and the energy consumption is high. The aerobic fermentation can utilize the residues generated by the anaerobic fermentation to carry out composting to produce the fertilizer, but the anaerobic fermentation gas generation and the aerobic fermentation fertilizer production are two mutually independent processes in the aspect of engineering operation, the methane and the organic fertilizer cannot be simultaneously produced, the gas generation and fertilizer production periods are both longer, more equipment is needed, the energy consumption is high, and the continuous operation efficiency of the engineering is influenced.
