The surface runoff of pig farm manure and urine open-air dumps during the rainy season is the main way to cause surface water and groundwater pollution. Therefore, how to effectively deal with the excrement and urine of large-scale pig farms is a major problem to be solved urgently. If there is a way to effectively treat the manure and sewage produced by breeding and reuse the manure, it can save a lot of money for the breeding industry and improve the comprehensive utilization rate.
