Problems solved by technology

[0002] When the livestock and poultry animals are dead, the high-temperature treatment process is usually used. The exhaust gas caused by the high-temperature treatment process, especially when the pressure is released, contains a large amount of non-condensable gas and odor components, resulting in a high load of odor treatment. Conventional treatment The process adopts acid-base washing + UV photolysis + biodegradation, but this process cannot solve the buffering of high-volume exhaust gas during pressure relief, and the treatment of sick and dead livestock and poultry at normal pressure cannot effectively sterilize
