Background technique

In recent years, with the rapid development of animal husbandry, the scale of animal husbandry has been increasing day by day, and the problem of livestock and poultry waste pollution has become increasingly prominent. The surface runoff in the open-air storage yard of pig manure and urine during the rainy season is the main way to cause surface water and groundwater pollution. Due to the strong leaching ability of feces and urine, the leaching amount of nitrogen, phosphorus and BOD in feces and urine is very large. If they are not properly treated, they will enter the groundwater layer through surface runoff and infiltration, or accumulate in the soil, causing Soil pollution. The manure of pig farms includes two aspects: solid and liquid: one is solid, that is, dry manure, which can be directly sold to farmers as fertilizer, and the other is liquid, that is, sewage, which is discharged from the ditch of the pig house to the sewage pool with high concentration. Organic sewage, while large-scale pig farm wastewater is mainly composed of urine, residual feces, feed residues and flushing water, etc. Some farms also include domestic wastewater generated during production. The former is the main part, of which flushing water accounts for the vast majority. Due to the high concentration of organic matter in pig farming wastewater, and it contains a large amount of nitrogen, phosphorus, suspended solids, pathogenic bacteria and other components, if these pollutants are not properly treated, once they enter natural water bodies and farmland, they will cause serious environmental pollution. .

Therefore, how to effectively process the pig farm manure for large-scale cultivation, and design a device for processing and utilizing the manure for large-scale cultivation will have very important significance and broad market application prospects.
