[0002] With the development of social economy and the improvement of people's living standards, the emission of organic waste is increasing. my country's organic waste production ranks among the top in the world and has become one of the main factors affecting environmental pollution. The use of reasonable technology to effectively treat and utilize organic waste is of great significance to saving natural resources, preventing and controlling environmental pollution, and achieving sustainable economic and social development. At present, the main treatment technologies include landfill, aerobic composting, incineration, anaerobic digestion, etc. The landfill method occupies a large area and requires a large investment, especially biomass energy is difficult to be effectively utilized, which is a waste of resources; the incineration method realizes energy and saves land, but the investment is high, and it will emit highly toxic dioxin-like gases, which has great environmental hazards. Aerobic composting and anaerobic digestion can make organic waste harmless, reduce the amount, and utilize resources.

[0003] The traditional aerobic fermentation device is a static aerobic fermentation device with natural ventilation or forced ventilation. The material starts from fermentation, and the temperature begins to drop after passing through medium temperature and high temperature. The whole process is carried out under aerobic conditions, and its disadvantage is that clean energy cannot be recovered. The traditional anaerobic fermentation technology is mainly liquid fermentation technology, which has been widely used and relatively mature. Liquid fermentation requires a large amount of water due to the low concentration of fermented materials, and a large amount of energy is required to reach the medium temperature or high temperature fermentation temperature, which greatly reduces the economic benefits of the project. As described in the patent document CN205676458U, a horizontal aerobic-anaerobic integrated fermentation device includes a fermentation device body, a sprinkler, a motor, a stirring shaft, a stirring blade, a percolation plate, a fan, etc. The stirring shaft is installed in a horizontal installation mode at the lower part of the fermentation device. One end of the shaft is connected to the motor through a coupling, and the other end is connected to the fan through a coupling; a sprinkler, an exhaust pipe and a biogas pipe are installed on the top of the fermentation device, and a percolation plate is arranged at the bottom. However, when solid-state fermentation occurs during use, it is difficult to take out the materials inside the mixing barrel, and the overall heating effect is poor. Utility Model Content
