【摘要】 径流雨水污染控制设计雨量的合理确定需针对具体汇水面的径流雨水水质特性。基于径流污染物的累积、冲刷及其与降雨量、径流量之间的关系提出了基于雨水水质的径流污染控制设计雨量计算方法。以北京城区屋面为例,针对其径流雨水水质状况,分析了污染累积与控制规律;基于近30年的降雨资料,利用该方法计算得出了其合理径流污染控制对应的设计雨量,可为其他城市或其他汇水面径流污染控制设计雨量的计算提供参考。更多还原

【Abstract】 Runoff quality of urban catchment is an important consideration to the estimating rainfall in runoff pollution control.A rainfall calculation method for runoff pollution control was developed based on runoff pollutant accumulation erosion and their relationship to rainfall and runoff.The runoff pollutant accumulation and control law were analyzed according to roof runoff quality in Beijing City.The reasonable rainfall estimation for runoff pollution control was obtained based on rainfall data with this method,and could be used as a reference in other cities and urban catchments.更多还原
