Before fermentation of pig manure, dry and wet separation is required, and aerobic fermentation is carried out using a pig manure fermentation tank.

Firstly, dry and wet separation is required before pig manure fermentation to prevent excessive ammonia production during the fermentation process. Ammonia is a harmful gas that can pose a threat to human health and the environment. Secondly, aerobic fermentation using pig manure fermentation tanks can better decompose organic matter and reduce environmental pollution. During this process, the organic matter in pig manure will be decomposed by microorganisms, producing harmless compounds such as biogas, carbon dioxide, and water. These harmless compounds can be utilized, such as as as fuel, biogas production, etc., to achieve resource recycling. In addition, using pig manure fermentation tanks for fermentation can also reduce the pollution of manure on surface water, groundwater and other environments, and protect the ecological environment. During the fermentation process of pig manure, attention should also be paid to some details. For example, the fermentation site should be selected as an indoor greenhouse, with a stacking height of no more than 1.5 meters and a width of no more than 2 meters to avoid affecting the fermentation effect. During the fermentation process, it is also necessary to pay attention to temperature changes. If the internal temperature reaches 60 ℃, it needs to be flipped once, wait for a second heating, and then heat up to about 60 degrees. Flip again and repeat several times until the material no longer heats up.

The use of pig manure fermentation tanks can not only reduce environmental pollution, but also achieve resource recycling.
