连云港市蔷薇河水质改善的若干建议

Suggestions on improving water quality of Qiangwei River in Lianyungang City

蔷薇河承担着连云港市城区生活、生产与生态等水源供给任务,同时也是沿线农业生产的重要水源。长期以来受农村农业面源污染、酸洗石英砂点源污染等因素影响,蔷薇河水质不稳定,尤其是高锰酸盐指数、氟化物等易发超标,水质改善难度较大。本文在统计梳理蔷薇河2018—2019年水质监测数据的基础上,系统分析了蔷薇河沿程水质变化情况及水质超标原因,并结合河长制工作实践,针对性地提出了改善蔷薇河水质的若干建议,以期为改善蔷薇河水质提供有益借鉴。

Qiangwei River undertakes the water supply tasks of life,production and ecology in Lianyungang City,and is also an important water source for agricultural production along the route.For a long time,affected by agricultural and rural non-point source pollution,acid-washed quartz sand point source pollution and other factors,the water quality of Qiangwei River is unstable,especially the permanganate index and fluoride are prone to exceed the standard,which makes it difficult to improve the water quality.Based on the statistical analysis of the water quality monitoring data of Qiangwei River in 2018—2019,this paper systematically analyzes the changes of water quality along Qiangwei River and the reasons of water quality exceeding the standard,and puts forward some suggestions on improving the water quality of Qiangwei River in combination with the practice of River Chief system,in order to provide useful reference for improving the water quality of Qiangwei River.
