| 摘 要： | 城镇地表径流污染是地表水体污染的主要原因,也是城镇河流的主要污染源之一,其识别和控制是目前城市水环境治理的重要内容。沙河是长江的二级支流,流经宜昌市某区,水体水质较差。以该区为研究对象,将其分为不同下垫面,通过监测次降雨不同时段各种下垫面地表径流中污染物浓度,建立地表径流污染物负荷估算方法,估算地表径流中污染物负荷量,为城市非点源污染削减和城市河流污染治理提供依据。

| Abstract: | The urban surface runoff pollution is one of the main reasons of water pollution, and one of the main pollution sources of the urban river as well. Identification and control of urban runoff pollution is of vital importance in the control of urban water environment at present. The Shahe River is a secondary tributary of the Yangtze River, flowing through a district in Yichang City, in which the water quality is relatively bad. As a research object, the district was divided into different underlying surfaces. And then, by monitoring the pollutant concentration from the different underlying surface runoff in various durations, a calculation method for estimation of the pollutant load from surface runoff is set up, which offers the basis for reducing non-point source pollution in urban area and controlling pollution in urban rivers. |
