Improve pig house air

The urine is treated separately and mechanized ventilation mode is adopted. The ventilation principle of air convection and negative pressure ventilation is used to quickly draw the indoor air away and discharge it to the outside. At the same time, a large amount of fresh air is sucked in to replace the air and allow the air to flow. Get up to ensure that the air in the pig house is effectively improved.

Strengthen the treatment of waste discharge

Strengthen planning and design. Use inefficient and idle land such as barren hills, slopes and mudflats to build farms and avoid living water sources. A reasonable slope should be designed in the site to ensure smooth drainage. At the same time, places closer to farmland, woodland or fish ponds should be selected to facilitate the timely use of the sewage. Establish a scientific manure treatment facility and raise awareness of environmental protection among management personnel, placing the use of pollutants in the same important position as preventing pollution. In addition, the scale of breeding should be designed based on the capacity of the local environment and the amount of livestock carried, and the capacity of surrounding farmland to absorb sewage.

Reducing the amount of fecal emissions in culture

The scientific design of the pig-raising process will be strengthened to improve the small environment in the pig house and reduce the unit discharge of the manure. Rationally design the pig's nutritional formula and reduce the elimination of residual nutrients in the urine to reduce environmental pollution. Deodorants, such as saponin and activated charcoal, are added to the pig breeding diet to reduce the production of ammonia in the manure.

Strengthen the use of manure

The excrement is used as fertilizer, and it can be made into green organic fertilizer after it is dilute and diverted and then transported out of the site, effectively promoting the integration of agriculture and animal husbandry with the virtuous cycle of agriculture. At the same time, manure and urine water must be treated to achieve harmless emission standards, so that pigs can be coordinated development. Encourage large and medium-sized aquaculture enterprises to support the construction of livestock and poultry manure storage, rain and sewage separation, and harmless treatment and comprehensive utilization of large and medium-sized biogas, etc., to carry out centralized supply of biogas, power generation, and production of organic fertilizers, and to popularize “pig-biogas-vegetables” and “ "Pig - marsh - fruit" and other benign development cycle of agriculture and animal husbandry. Encourage and support small-scale farmers and free-range households to adopt the combination of planting and breeding to eliminate the use of livestock and poultry breeding waste, and promote the use of livestock and poultry excrement, sewage and other wastes on the spot.

Strengthen the farm's environmental treatment

Strengthen the treatment of the external environment of the farm, and plant more trees and grasses to improve the pig farm and its surrounding environment. Between each pig house, tall deciduous trees and fast-growing trees can be planted. Wind-break forests can be planted outside the farm area. Flowers, grasses and vegetables can be planted in open areas on the farm. This can effectively reduce the toxic and harmful gases in the air in the field. In addition, we should also strengthen the treatment of the internal environment of the pig farm, control the temperature and humidity inside the pig house, do a good job in pig house sanitation, do regular inspections and regular cleaning, so as to effectively prevent environmental pollution in the pig house and promote Pigs grow and develop.
