镇江市太湖流域地区氮磷污染来源解析及防治对策

Nitrogen and Phosphorus Pollution in the Taihu Basin in Zhenjiang and Counter Measures

本研究在大量监测和调研数据的基础上全面分析了镇江市太湖流域两条主要河流—京杭运河和丹金溧漕河沿岸地区氮磷污染来源,结果表明:两条河流沿岸氮素污染物主要来源于生活污水,磷素污染物主要来源于农业面源污染。工业污染中,化工行业为污染物排放最大的行业。最后,根据污染来源情况针对性的从控源截污、发展有机生态农业、加强环境管理和监控等方面提出了镇江市太湖流域氮磷污染控制对策。

In the study, the water quality and the nitrogen and phosphorus pollution were investigated. The results showed that Jinghang Great Canal and Dan Jin Li Cao River in Zhenjiang was confronting a severe water pollution problem due to high level presence of both nitrogen and phosphorus in the effluent. The nitrogen pollution mainly came from domestic sectors, while the phosphorus pollution mainly came from agricultural non-point source. Pollution of industry was also a large problem, and the chemical industry was the industry branch of the maximum pollutant discharge. Based upon the above analysis, the control countermeasures of nitrogen and phosphorus were proposed to improve the aquatic environment of Taihu Basin in Zhenjiang area such as reinforcing pollution comprehensive treatment, carrying out river and ecological restoration engineering, strengthening environmental management and monitoring, etc.
