摘要
针对污染地表水环境的城市径流污染源,利用SCS降雨径流模拟建立了城市径流不同土地利用类型径流系数与年降雨量的相关关系,其相关性显著;在不同降雨强度条件下,对典型示范区城市排污口实施降雨过程监测,获得了有代表性的城市径流污染物平均浓度,从而估算出辽宁省城市径流污染负荷总量。
Aimed at the pollution source that polluted the environment of surface water and based on the soil conservation service （SCS） of runoff simulation, the correlativity between annual precipitation and runoff coefficient of different land use types was established,which was significant. Moreover, under the different rain intensities, the rainfall process in urban sewage outfall of typical demonstration zone was monitored. And the average pollutant concentration of urban runoff in representative city was obtained, which provided the gist to research the pollution load in urban runoff. Sequentially, the gross of urban runoff pollution load in Liaoning province was evaluated.
