[0002] Using livestock and poultry manure as raw material, anaerobic fermentation produces biogas. The biogas can be used to generate electricity or purified into biomethane for vehicle, residential, or corporate use. At the same time, the biogas residue and biogas slurry can also be used to prepare good organic fertilizer. Anaerobic fermentation of livestock and poultry manure to produce biogas reduces the impact of pollution on the surrounding environment.

[0003] The utility model disclosed in CN216711868U is a fecal treatment device, including a fecal tank, an aerobic chamber, an anaerobic chamber, and a biogas collector. The anaerobic chamber is connected to the fecal tank in sequence through a liquid guide pipe and a flushing pipe. The fecal tank is connected to the aerobic chamber through a discharge pipe. The anaerobic chamber is connected to the aerobic chamber in sequence through a reducing pipe, a liquid guide pipe, a reducing double U-shaped pipe, and a sewage pipe. The aerobic chamber is connected to the biogas collector in sequence through a gas guide pipe and a gas-liquid separator. The biogas collector is connected to a gas pump through a single U-shaped pipe. The gas pump is connected to the anaerobic chamber in sequence through a gas-liquid separator and a gas guide pipe.

[0004] The above-mentioned technical solution allows the fecal treatment device to produce biogas, reducing rural pollution; however, the fermentation of the fecal treatment is not sufficient, making it difficult to carry out fermentation at different temperatures in multiple layers, and the residue after fermentation is not easy to dehydrate and press into shape to reduce the impact of direct discharge on environmental pollution.
