The environmental issues of environmental protection design and pollution prevention and emission reduction measures in China's swine farms have become one of the most important issues in the modern era. Since the reform and opening up, China's swine industry has developed rapidly. However, environmental pollution caused by farming has become increasingly prominent and has become an agricultural pollution control. The focus and difficulty. For the livestock husbandry, giving consideration to environmental protection and animal husbandry is a huge challenge and opportunity. I. The State's Attitude towards Environmental Issues on Pig Farms According to incomplete statistics, in 2014, about 10,000 farms of all sizes were warned by the government and ordered to be dismantled due to environmental issues (violation of buildings, odors, and non-compliance of pollutants, etc.). Such a large quantity shows that the country is making great efforts to rectify the pollution problems caused by the livestock and poultry breeding industry, and it also shows that there are many deficiencies in the animal husbandry and aquaculture industry in terms of environmental protection, which has sounded alarm bells for many farmers. The state has issued a series of relevant regulations and policies for the construction of pig farms. According to the law, at the beginning of the construction of a farm, if there is no environmental impact assessment report, it is an illegal building and a corresponding penalty will be imposed. The pollution control facilities of livestock and poultry farms must be designed, constructed and used at the same time as the main project. Sewerage should also be installed in accordance with the provisions of automatic monitoring equipment and supporting facilities, or will be fined. Livestock and poultry farms must set up storage facilities for livestock and poultry waste, and reinforce the ground to prevent the leaching of livestock and poultry wastes due to rainwater. At the same time, they must also prevent foul odors from causing pollution and harm to the surrounding environment. Animal excrement, infected animal products, dead animals or animal dead bodies or excrement and other contaminants whose cause of death is unknown shall be handled in accordance with the regulations of the State Council's veterinary department. Livestock and poultry farms must obtain a "pollution permit" and discharge pollutants as required. II. Construction of Environmental Pig Farms 1, the planning of the farm When planning on a farm, first of all, determine the nature of the farm, such as the main farmed pigs or breeding pigs, or both; the second is to make clear the scale of the farm, mainly based on the number of rearing sows and commodity pigs to distinguish. It is divided into four types: large, medium and small scale and retail. 2, farm site selection The location of the farm should meet the national environmental protection requirements and follow the principles. Compliance with environmental protection requirements is a prerequisite for the establishment of a new farm site, and should comply with the principles of bio-security (ie comply with public health and safety, environmental protection, animal welfare, veterinary health requirements, through the environmental impact assessment report, access to "animal epidemic prevention certificate" Such as documents, urban middle and long-term development principles, land use planning and land-saving principles, five areas (ie, tourist areas, nature reserves, water conservation areas, livestock and poultry epidemic areas and environmental pollution areas of serious pollution) should not be the principle. The construction of pig farms is also closely related to the topography and topography. The selected topography should be neat and open, which is conducive to air diffusion and can effectively excrete manure and muddy gas, thus ensuring the environmental quality of the entire plant area. In addition, the topography of the construction farm is required to be high, dry, leeward, flat and slightly gentle. The pig farm should be built in a place convenient for hydroelectric transportation. First of all, the farm's production water source must meet the following conditions: sufficient water quantity, water quality meets hygienic requirements, convenient access, and easy sanitation protection, purification and disinfection. Secondly, the farm should be close to the power supply to ensure that the pig farm can obtain sufficient and stable power while saving the cost of power transmission and transformation. Finally, due to the huge amount of transportation of feed ingredients, products, waste, and waste, it is advisable to have feed suppliers nearby, and the products can be sold nearby. There is a large area of ​​farmland nearby, and waste and waste can be used and disposed on site. . At the same time, it should be noted that pig farms should avoid traffic trunks to prevent their interference. In addition, large-scale farms must set up special channels for transportation of feed, pigs and manure to avoid cross-infection. Third, measures to reduce environmental pollution 1, increase the conversion rate of feed Raising the feed conversion rate is a fundamental measure to reduce the environmental pollution of the pig house. Increasing the digestibility of nutrients in the feed and reducing the metabolism can effectively reduce the nutrient content in the excreta. The use of microbial fodder fermented feeds to feed livestock, such as gems fodder starters, can increase nutrients and improve feed utilization, as well as removing fecal odors and purifying the ecological environment. 2. Cleanup of feces The methods for cleaning feces include artificial collection, water flushing, blisters and fermentation beds. Pig farms can choose according to their own situation. Although the manual collection of daily workload is small, but the current manual salary level is high, and few people are willing to engage, it does not apply to large-scale pig farms; water flushing manure consumes a lot of water resources, it does not apply to water resources strained Pig farms; blisters have the advantage that they do not require frequent handling of pig manure, but if handled improperly, they will produce a large amount of ammonia odor and cause environmental deterioration; Jinbao dry-type fermentation bed is a mixture of pig feces and litter for heat production. No manual cleaning of manure is required. The fermentation of golden baby's beneficial microorganisms can promote the growth of pigs and deal with the pollution of pig manure. It not only meets the requirements of environmental protection, but also saves energy and saves grain, promotes disease resistance, and promotes the growth of poultry such as pigs, chickens and ducks. The effect is better, but it is necessary to decide whether to turn over the litter according to the condition of the dunghill every day. Jinbao dry-type fermentation bed breeding mode is no longer unfamiliar to the majority of farmers, is currently in line with national environmental protection requirements but also protect farmers vital interests are not a win-win choice, in the face of national environmental protection continues to increase What are you waiting for?
