Pig farm odor refers to gas substances that have harmful effects on humans and pigs, as well as gases that make people's sense of smell unpleasant. The foul odor in pig farms mainly comes from the decomposition of pig feces, sewage, bedding, feed, etc; In addition, fresh pig feces, gases expelled from the digestive tract, secretions from sebaceous and sweat glands, dirt adhered to the body surface, and CO2 in exhaled breath (which is about 100 times higher than the atmosphere) all emit unpleasant odors. In large-scale breeding farms, typically a pig farm with an annual output of 10000 pigs can produce at least 30000 tons of sewage. Under suitable temperature, humidity, anaerobic environment, and fermentation conditions, it can produce a large amount of foul odor; At the same time, in daily management work, the cleaning of sewage ditches, ventilation of pig houses, and other hygiene management measures in pig farms are often neglected, resulting in high concentrations of odorous gases (such as NH3 concentration sometimes exceeding 40 milligrams per cubic meter), which pose serious hazards to human physical and mental health, as well as the health and production performance of pig herds. This has become a prominent problem in the hygiene management of pig farming production. To improve pig farming efficiency and improve the environment of pig farms, comprehensive measures such as new technologies and instruments need to be adopted to remove or reduce the harm of odorous gases.
