里水河水污染评价分析及防治对策

Water Pollution Assessment Analysis and Prevention Measures of Lishui River

基于2016年9月至2018年8月的广东省佛山市境内里水河水质污染超标部分进行分析,得出了里水河水质评价及污染物相关特征,并提出了相应的防治对策。结果表明:里水河水质污染超标情况普遍;超标的项目有氨氮、总磷、溶解氧、生化需氧量(BOD)、化学需氧量(COD),其中氨氮和总磷为主要污染物;里水河的污染有向复杂化、多样化的趋势发展。

Based on the analysis of the excessive pollution of Lishui River in Foshan City,Guangdong Province,from September2016 to August 2018,the paper obtains the water quality evaluation and pollutant-related characteristics of Lishui River,and puts forward the corresponding prevention and control measures.The results show that the water quality of Lishui River is generally polluted beyond the standard;the items that exceed the standard are ammonia nitrogen,total phosphorus,dissolved oxygen,biochemical oxygen demand(BOD),chemical oxygen demand(COD),in which ammonia nitrogen and total phosphorus are the main pollutants;the pollution of Lishui River has a trend of complexity and diversification.
