金华江流域典型乡镇水质监测评价及污染控制

The Assessment and Pollution Control of Water Quality Monitoring of the Typical Towns in Jinhua River Region

摘要: 金华江为钱塘江上游最大的支流，水质污染较重，氨氮、总磷污染尤为突出。该文针对金华江水质污染的特点，对金华江流域沿河典型乡镇干流及主要支流进行了高密度监测，通过对监测数据的详细分析，对各沿江乡镇地表水水质污染现状进行了评价。结果表明，金华江流域的污染以氨氮为主，总磷为第二污染物，上游乡镇未受明显污染，中游乡镇氨氮污染最为突出，下游乡镇污染趋势于下降，针对各乡镇不同的水质污染特征分析了成因并提出控制对策。
