摘要
瓜泾口北断面为重点流域控制断面,2019年水质考核目标为Ⅳ类,2015年12个月水质监测结果显示,瓜泾口北断面氨氮尚不能达标。该研究对瓜泾口北断面水环境现状进行了调查,分析了污染物入河量及构成,诊断和识别主要水环境问题,通过水文水质模型构建及模拟计算,提出保障断面达标的污染物削减方案。
The section of North Guajingkou is key watershed control section, and the water quality assessment objec- tive for 2019 is class 1V.Water quality monitoring results of twelve months in 2015 showed that the water quality in- dex of ammonia nitrogen could not achieve standards.The present water environment situation of North Guajingkou section is investigated, the pollutant inlets into river and constitute are analyzed, and the main water environmental problems are diagnosed and identified.Through construction and simulation calculation of hydrology and water quali- ty model, the pollutant reduction plan is put forward to ensure attaining standards of the section.
