Description

Technical Field

[0001] The utility model relates to a pig house deodorizing device for a pig farm. After the odor generated by the pig farm is introduced into the pig house deodorizing device, ammonia and hydrogen sulfide gases in the odor are adsorbed and degraded under the adsorption and metabolism of activated carbon and aerobic microorganisms in the deodorizing device, thereby reducing the odor concentration in the pig house. Background Art

[0002] At present, the treatment of odor in pig houses in pig farming is an industry-wide problem. The increase in odor concentration in the pig house will affect the healthy growth of pigs in the house and the lives of the breeders in the house. When the ammonia concentration in the pig house reaches the limit, it will cause the death of pigs and illness of breeders.

[0003] At present, the main method for treating odor in pig houses is wet curtain treatment. The odor containing ammonia and hydrogen sulfide gas in the pig house is introduced to the surface of the wet curtain through the induced draft fan. Under the action of spray water, the ammonia in the odor is dissolved in water, so that it can be removed from the odor. After the ammonia in the pig house is removed, the odor concentration in the house will drop significantly. The existing wet curtain odor treatment method has the disadvantage that the wastewater generated is difficult to treat. Ammonia forms ammonia water after dissolving in water. If ammonia water is not treated, it will inevitably pollute the environment. The existing wet curtain treatment needs to be used in conjunction with the subsequent sewage treatment system.
