Investigation shows that the prevention and control of livestock and poultry breeding pollution in China is urgent

Introduction: with the rapid development of China's animal husbandry, livestock and poultry breeding pollution has become the main source of rural pollution in China, pollution prevention and control work is urgent According to a survey of large-scale livestock and poultry breeding pollution conducted by the State Environmental Protection Administration in 23 provinces, autonomous regions and municipalities directly under the central government, the annual production of livestock and poultry manure in China is about 1.9 billion tons, 2.4 times of industrial solid waste, and even more than four times in Henan, Hunan, Jiangxi and other regions Among them, COD (chemical oxygen demand) of livestock and poultry manure has reached 71.18 million tons, far more than the total discharge of industrial wastewater and domestic wastewater in China According to the survey, the overall land load warning value of livestock and poultry manure in China has reached 0.49 (less than 0.04 is appropriate), reflecting a certain level of environmental stress Beijing, Shanghai, Shandong, Henan, Hunan, Guangdong, Guangxi and other places have exceeded zero point four nine, showing a relatively serious level of environmental pressure Because many large-scale livestock and poultry farms in China are located in areas that have environmental impact on residents, even in residential areas, the nearest distance between 8-10% of large-scale farms and residents or water sources is no more than 50 meters, and the nearest distance between 30-40% of large-scale farms and residential areas is no more than 150 meters, which brings about pollution to residents' lives And metaphor In response to the above problems, the State Environmental Protection Administration issued the measures for the prevention and control of pollution in livestock and poultry breeding this year, and began to strengthen the prevention and control of pollution in livestock and poultry breeding industry Relevant people said that the State Environmental Protection Administration will organize and guide the local government to determine the list of key environmental management farms and key control areas, and protect and improve the rural ecological environment by strengthening comprehensive utilization and carrying out pollution prevention and control demonstration projects (author:) share to feed Weibo share to:
