生猪养殖环境污染及防控措施

Environmental Pollution in Pig Breeding and Its Prevention and Control Measures

近年,规模化生猪养殖场的建设数量不断增加,养殖效益大幅度提升,但生猪养殖环境污染已经成为农村环境污染的主要来源。没有经过妥善处理的猪粪尿,经过发酵后产生大量有毒有害物质,挥发到大气中或随着雨水冲刷渗入地下水或地表水,造成公共水系的硝酸盐含量严重超标,对周边居民的生命财产安全造成严重威胁。

In recent years,the number of large-scale pig farms has been increasing,and the benefit of pig farming has been greatly improved.Pig waste,which has not been properly treated,has been fermented to produce large quantities of toxic and harmful substances,which are released into the atmosphere or leached into groundwater or surface water as rain water washes them away,resulting in high levels of nitrate in public water systems,it poses a serious threat to the lives and property of the surrounding residents.
