Research On Pollution Prevention And Control Of Livestock And Poultry Breeding In F County, Chongqing City

County F of Chongqing is located in the heartland of the Three Gorges Reservoir area.The surface water system is mainly the Yangtze River.The rivers in the territory belong to the Yangtze River system.Under the background of large pollutant discharge and many hidden dangers,ensuring the ecological environment safety of F County of Chongqing City in the Three Gorges Reservoir Area of the Yangtze River is the only way for F County of Chongqing to implement the new development concept and realize ecological priority and green development.Pollutants from livestock and poultry farming have become an important source of agricultural non-point source pollution.According to the first national pollution source census data in 2010,agricultural non-point source pollution accounted for 57% of total national pollutant discharge in China,while agricultural non-point source pollution Livestock and poultry breeding accounted for 68% of pollution emissions.Livestock and poultry breeding contributed96% of chemical oxygen demand,38% of total nitrogen,and 56% of total phosphorus in agricultural non-point source pollution emissions.The current pressure on ecological environment protection has become a limiting factor restricting the further development of livestock and poultry breeding.How to realize the modern and green development of livestock and poultry breeding has become an urgent problem to be solved.How to adopt efficient and economic policies and measures to promote the owners of breeding and comprehensive utilization of pollutants from livestock and poultry breeding is urgent.This article is based on theories of severe externalities in livestock and poultry farming,the conflict between the value of livestock and poultry farming and the ecological environment,and the urgent need for public governance of pollution in livestock and poultry farming,taking F County in Chongqing as an example.Discuss the livestock and poultry breeding and its pollution in F county of Chongqing city,find out the problems of livestock breeding and governance in F county of Chongqing city,find the difficulties in comprehensive government supervision,direct discharge of breeding pollutants into the external environment,abnormal operation and scale of pollution prevention facilities The following problems are serious pollution of farming and insufficient comprehensive utilization of farming waste.Analyze the cause of the problem,and then propose the optimal countermeasures for the prevention and controlof pollution in livestock and poultry farming: strengthen multi-party cooperation and clarify the division of responsibilities;strengthen publicity and guidance to enhance ecological awareness;provide technical services to deal with farming pollution;increase capital investment and reduce pollution control costs;scientific compilation Plan and regulate breeding areas.
