Treatment method of sewage from chicken farm

Chemical treatment method: the chemical solids can be easily eliminated by adding chemicals such as aluminum sulfate and ferric trichloride to the sewage, and the method is simple and low cost. Filtration method: the sewage is filtered into clean water for reuse, the cost is slightly higher, but it is recommended. Primary sedimentation tank: the relatively small sewage particles are condensed into large solids and then treated, with low technical content. Biological way: decompose the microorganisms and sewage in the soil, the treated sewage is higher than the discharge standard index, the cost is low and very scientific.

The sewage of chicken farms is not treated by environmental protection, so it is easy to affect the surrounding environment, so the state environmental protection department has been strictly sealing down unqualified chicken farms in recent years. At present, the common treatment methods in the market are filtration, primary sedimentation tank and so on. The more scientific treatment is the chemical and biological methods.

1. Chemical method

Chemicals such as aluminum sulfate and ferric trichloride can be added to the sewage. After dissolving the sewage quickly, it will become a solidified chemical agent. At this time, it is relatively easy to eradicate these chemical solids. This method is very simple and low cost.

2. Filtering method

In fact, in order to the utilization rate, the sewage can also be filtered into clean water for reuse, although the cost will be relatively high, but in the long run, it is still a recommended way, most chicken farms choose biofilter for filtration.

3. Primary sedimentation tank

It belongs to the wastewater treatment method that most people are familiar with, and the principle is that the relatively small sewage particles are condensed into large solids and then treated. This method can be solved without technology, not only in chicken farms, but also in domestic sewage.

4. Biological mode

At present, the use of biological treatment is also a very scientific way to decompose the microorganisms and sewage in the soil, which is not expensive and does not require too much electricity. And the treated sewage can be higher than the discharge standard index.
