China sets standards to limit the pollution of livestock and poultry breeding industry

Introduction: the amount of waste water discharged by one pig per day is equivalent to the waste water generated by 7 people's daily life, and the amount of waste water discharged by one cow per day is more than the waste water generated by 22 people's daily life Animal husbandry has become an important factor of environmental pollution China's State Environmental Protection Administration recently released the emission standard of pollutants from livestock and poultry breeding industry to tackle the pollution problems in livestock and poultry farms and breeding areas The establishment of this standard shows that after the prevention and control of industrial pollution and urban environment, China has brought the problem of agricultural pollution into the field of vision According to reports, this standard is applicable to intensive and large-scale livestock and poultry farms and breeding areas, not to scattered livestock and poultry farmers It aims to encourage ecological breeding, promote the sustainable and healthy development of livestock and poultry breeding industry, promote the utilization of resources in the waste treatment process of livestock and poultry farms, and reduce the amount of end pollutants According to the survey, at present, the average scale of China's breeding farms is 650 pig farms and 22000 chicken farms, of which the number of small and medium-sized livestock and poultry breeding accounts for more than 70% of the total amount of breeding, resulting in pollution which is the main part of the pollution of the national breeding industry In order to effectively control the pollution of aquaculture, the standard not only strictly controls the pollution of aquaculture, but also lists a large number of small and medium-sized farms as control objects According to the technical and economic conditions of pollution control of livestock and poultry breeding industry in China, the scale of livestock and poultry farms is divided into one and 22 levels All intensive livestock and poultry farms and breeding areas within the scope of first level scale, and intensive livestock and poultry farms and breeding areas within the scope of second level scale and located in key national environmental protection cities, key river basins and seriously polluted river network areas, shall implement this standard from January 1, 2003 For intensive livestock and poultry farms and breeding areas within the scope of secondary scale in other areas, the implementation time of the standard shall not be later than July 1, 2004.
