Odour purifying system in livestock and poultry breeding farm and application method thereof

Abstract

The invention discloses an odour purifying system in a livestock and poultry breeding farm and application method thereof. According to the odour purifying system in the livestock and poultry breedingfarm, an underground gas channel and a gas purifying deice are arranged in the farm, wherein the underground gas channel is used for introducing contaminated air in the farm into the gas purifying device; the gas purifying device purifies the contaminated air through a porous biological deodorant wall body, an ultraviolet disinfecting lamp and the like. According to the odour purifying system inthe livestock and poultry breeding farm and the application method thereof, the flowing direction of the air in the breeding farm is changed; the influence of harmful substances, such as ammonia and nitrogen, in the contaminated air on the livestock and poultry is eliminated; meanwhile, atmospheric propagation of the pollutants and pathogens discharged by the breeding farm is eliminated.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a system for purifying odor in livestock and poultry farms and an application method thereof. Background technique [0002] With social and economic development, fundamental changes are taking place in the way, structure and mode of livestock and poultry breeding. On the one hand, more and more rural laborers are migrating to work in cities, and the income of farmers has increased, resulting in fewer and fewer free-range livestock and poultry in rural areas; , The increase in cost has also led to the gradual reduction of free-range farming in rural areas. In recent years, the progress of my country's agricultural science and technology, especially the continuous rise in the price of livestock and poultry products, has caused a large amount of social funds to invest in the breeding industry, promoted the rapid transformation of livestock and poultry breedi...

Problems solved by technology

[0005] At present, in order to improve the air quality in livestock and poultry breeding houses and reduce the harm of harmful gases to livestock and poultry breeding itself, the commonly used method is to strengthen the ventilation of breeding houses. The disadvantages are: (1) the source of pollutants in the air in the house It is manure. During the ventilation process, the air in the house rises from the manure on the ground and is discharged from the upper part, which increases the release of pollutants in the manure to the air in the house, and improves the air quality of the livestock and poultry activity area near the ground. Not much; (2) This ventilation method does not purify the gas and directly discharges it into the atmosphere outside the house; (3) Pollutants in the dirty gas of pig farms induce pig diseases and the spread of pathogenic bacteria in pig farms The source of the plague outbreak has brought a huge impact on the breeding industry; (4) The ammonia discharged from the farm is one of the main sources of atmospheric ammonia, and the ammonia in the atmosphere is the most important precursor of secondary aerosol particles, which is the cause of One of the chief culprits of smog, from the perspective of improving the atmospheric environment, it is also necessary to control the ammonia emissions of livestock and poultry farms
