A Detailed Explanation of Chicken Farm Sewage Treatment Methods and Technical Points

Abstract Chemical treatment method: Chemical agents such as aluminum sulfate and ferric chloride are added to the sewage, making it easy to remove chemical solids; the method is simple and low in cost. Filtration method: The sewage is filtered into clean water for reuse; the cost is slightly higher but it is worth recommending. Primary sedimentation tank: Relatively small sewage particles are coagulated into larger solids and then treated; the technical content is low. Biological method: Microorganisms in the soil decompose the sewage, and the treated sewage exceeds the discharge standard index; the cost is low and it is very scientific.

If the sewage from a chicken farm is not treated for environmental protection, it can easily affect the surrounding environment, so the national environmental protection authorities have been strictly shutting down substandard chicken farms in recent years. At present, the more common treatment methods on the market include filtration and primary sedimentation tanks. The more scientific treatments are chemical methods and biological methods.

1. Chemical method

Chemical agents such as aluminum sulfate and ferric chloride can be added to the sewage; after quickly dissolving the sewage, they turn into solidified chemical agents, and at this point these chemical solids can be removed fairly easily. This method is very simple and the cost is also very low.

2. Filtration method

In fact, for the sake of utilization rate, the sewage can also be filtered into clean water for reuse. Although the cost will be relatively higher, from a long-term perspective it is still a highly recommended method. Most chicken farms choose biological filter towers for filtration.

3. Primary sedimentation tank

This is a wastewater treatment method that most people are relatively familiar with. The principle is to coagulate relatively small sewage particles into larger solids and then treat them. This method can be solved without technology, and it is not only usable on chicken farms; it is equally practical for domestic sewage.

4. Biological method

Using biological treatment is also a very scientific method at present. Microorganisms in the soil decompose the sewage. The cost of this method is not high either, and it does not require much electricity. Moreover, the treated sewage can also exceed the discharge standard index.
