[0002] Rural biogas has the dual functions of renewable energy production and environmental improvement. Small biogas projects (about 30m 3 -300m 3 ), which can adapt to the current situation of poor operation, maintenance and management in rural areas, process agricultural waste with low cost and low energy input, provide stable clean energy, and effectively reflect the comprehensive benefits.

[0003] The raw materials used in the fermentation tank are slaughter wastewater residue, manure from livestock and poultry farms such as cattle, pigs, and chickens, as well as urban domestic sludge, restaurant kitchen waste, etc. During the biogas fermentation period, it is necessary to ensure that the fermentation raw materials and microorganisms are in a completely blended state. The disturbance and blending of the fermentation raw materials in the existing fermentation tanks are not comprehensive enough, which makes it easy for the raw materials to accumulate on the bottom wall inside the fermentation tank, resulting in uneven distribution of the raw materials in the fermentation tank, and the raw materials are also easy to adhere to the inner wall of the fermentation tank, which is not conducive to the subsequent cleaning of the fermentation tank. Therefore, a biogas fermentation tank is proposed. Summary of the invention
