Tips for deodorizing pig farms

The smell of pig farms can be said to be the most disgusting reason for many pig farms besides manure by the surrounding residents. The manure is treated, but the odor is not so easy to remove. To do a good job in eliminating the odor of pig farms still needs some work, so how to solve the problem of odor in pig farms? A small tips for deodorizing pig farms.

Not only for the sake of less unpleasant smell in the pig farm, but also for the health of the pig’s respiratory tract. If the concentration of ammonia gas is too high, it will cause diseases such as cough and bronchitis in pigs. Pig farms are not indifferent to the odor. Most pig farms will use planting trees and grass for greening, and installing negative pressure ventilation systems in pig houses to solve the problem. But the smell is not so easy to get rid of. Is there any other plan that is acceptable to farmers, practical in operation, and effective in use?

1.Deodorization should start with emission reduction facilities. Emission reduction facilities are standard equipment for large-scale pig farms and can also adapt to the complex conditions of different pig farms. The first is the cleaning method. Remove feces and dirt in time, reduce dust and microorganisms in the house, and try to separate feces and urine. Change the blister manure to dry clean manure, because the treatment method of blister manure makes the manure stay in the pig house for a long time, resulting in anaerobic reaction and a large amount of odor. In addition, the contamination concentration of the manure-water mixture is high.

2.Improve the pig farm environment. Wu Yinbao, a professor at South China Agricultural University, introduced that green trees should be planted around pig houses to form a protective barrier. For example, locust trees and eucalyptus trees have adsorption properties and can absorb part of ammonia gas. Ventilation port plus wet curtain ventilation system, ammonia gas is soluble in water, and the discharge of ammonia gas can be reduced through the wet curtain.

The composition of Wusen 5S pig farm exhaust gas purification system: it is composed of filter screen, spray system, dosing system, sewage system and control device. It is divided into two modes: horizontal ventilation deodorization and vertical ventilation deodorization.

3.Sewage ponds and sunshade nets are added to reduce the spread of odors. In the waste treatment process, odors are mainly generated in solid-liquid separation sewage ponds and pretreatment acidification ponds. Wu Yinbao said that the sewage pool and acidification pool can be covered with sunshade nets to reduce the spread of odor. It can also be sprayed on the manure with deodorizing microorganisms to decompose it through microorganisms.

4.”Adding special additives, such as lactic acid bacteria, can convert excess ammonia nitrogen into bacterial protein and reduce air pollution.” It can be added to drinking water, feed, or even sprayed in pig houses to reduce the odor of the surrounding environment.

5.In order to further make the deodorizing effect of the bacteria operable. Farmers can also consider purchasing related machines. Electric dusters and portable ammonia detectors are all low-cost equipment that farmers can consider buying.
