Pig plant breeding sewage treatment project
Release time:
2024-06-25
The sewage of the pig factory mainly includes pig urine, part of pig manure and washing water of pig house, which belongs to high concentration organic sewage, and the content of suspended solids and ammonia nitrogen is large. After this untreated sewage enters the natural water body, the content of suspended solids, organic matter and microorganisms in the water increases, changes the physical, chemical and biological community composition of the water body, and deteriorates the water quality. Sewage also contains a large number of pathogenic microorganisms will spread through water or through aquatic animals and plants, endangering human and animal health. Therefore, the sewage treatment system of this project adopts the process flow of solid-liquid separation pretreatment anaerobic treatment aerobic treatment advanced treatment.
