摘要
在我国大部分养猪场缺乏统一规划,也没有建设必需的污水处理设施,养猪场未经处理的污水中含有大量的污染物质,污染负荷很高,养猪场污水排入自然水体中导致水体严重富营养化。严重时使水体发黑、变臭,造成持久性的污染,使原有的水体丧失使用功能,且治理和恢复难度很大。
In most pig farms in China,there is no unified planning,and there is no necessary sewage treatment facility.The untreated sewage in pig farms contains a lot of pollutants,the pollution load is high,and the sewage from pig farms is discharged into natural water bodies.The water body is seriously eutrophic.In severe cases,the water body becomes black and odorous,causing persistent pollution,which makes the original water body lose its function of use,and it is difficult to control and recover.
