The pig farm smells so bad, what can be used to deodorize it quickly?

The odor in pig farms is mainly caused by pig manure. Therefore, deodorization requires a multi-pronged and comprehensive approach. 1. Deodorize through clever feeding. Enzyme inhibitors can be added to pig feed, which can reduce nitrogen and ammonia emissions from pigs and reduce odor. 2. Physical deodorization. Charcoal, activated carbon, cinder, quicklime, etc. can be placed in a mesh bag and hung in the pen to play an adsorption role to reduce odor. 3. Chinese herbal medicine deodorizes. You can use moxa leaves, atractylodes, big green leaves or garlic oranges in a certain proportion and burn them in the pen to achieve a deodorizing effect. 4. Chemical deodorization. Pig manure should be cleaned up in time every day, piled together, and sprinkled with ferrous sulfate, which can inhibit the fermentation and decomposition of manure and reduce odor.

Ventilation should also be strengthened at ordinary times, and cleaning and disinfection should be carried out in a timely manner
