What are the sewage treatment methods of livestock and poultry farms

In recent years, the environmental pollution problem of large-scale breeding industry has become increasingly prominent. Because there is not enough land in the suburbs of the city to absorb a large amount of livestock and poultry manure, there has been a phenomenon of random discarding and discharge of livestock and poultry manure and sewage, which has brought great harm to large and medium-sized cities. huge environmental pressure.

At present, livestock and poultry manure and sewage have become the main pollution sources in the surrounding areas of cities and towns. Farm sewage mainly includes urine, some feces and flushing water, which is a high-concentration organic sewage, and contains a large amount of suspended solids and ammonia nitrogen. After this untreated sewage enters the natural water body, it will increase the content of suspended solids, organic matter and microorganisms in the water, change the physical, chemical and biological community composition of the water body, and deteriorate the water quality. Sewage also contains a large number of pathogenic microorganisms that will spread through water bodies or through aquatic animals and plants, endangering the health of humans and animals.

Therefore, it is imminent to carry out sewage treatment on farms, so what methods are there? The integration is to integrate the primary settling tank, I/II contact oxidation tank, secondary settling tank and sludge tank, and carry out blast aeration in the I\II contact oxidation tank to further improve the sewage treatment level.

Here we can recommend the advantages of an integrated sewage treatment method.
1. The integrated sewage treatment equipment has the ability to remove nitrogen and phosphorus, and can achieve the ability to treat industrial wastewater, domestic sewage, and urban sewage by adjusting the structure of the equipment.
2. The integrated sewage treatment equipment has a strong ability to resist shock loads.
3. The integrated sewage treatment equipment is easy to complete automatic control, management and operation.
4. The submersible pump of integrated sewage treatment equipment can be installed in the equipment to reduce project investment.
5. The effluent water quality of the integrated sewage treatment equipment is stable, and the sludge output is small and easy to handle.
6. The integrated sewage treatment equipment can be installed on the ground or buried underground. When buried in the ground, the upper part can be used for greening, and the factory covers a small area and there are few ground structures.
