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. pollute. The feces of pig farms include two aspects: solid and liquid: one is solid and the other is liquid, that is, sewage, which is discharged from the ditches of the pig house to the high-concentration organic sewage in the sewage pool, while the waste water of large-scale pig farms is mainly composed of urine. Liquid, residual feces, feed residues and flushing water, etc. Some sites also include domestic wastewater generated during the production process. 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 deal with large-scale pig farm wastewater, there are still many gaps in the promotion and application of the sewage treatment method for large-scale farming, and designing a device for the sewage of large-scale farming will have very important significance and broad market application prospect.
