摘要
采用其它方法对城市排水环境非点源负荷进行控制时,计算得到的非点源污染负荷与实际不符,控制后的污染物在降雨环境下的浓度没有明显降低,存在计算精准度低和有效性差的问题。提出多雨城市排水环境非点源污染负荷控制方法,通过暴水雨管理模型、径流曲线数值方程、土壤流失方程、输出系数模型构成非点源污染负荷模型,利用简易法和输出系数法对非点源污染负荷模型进行求解。采用多因子综合分析法结合非点源污染负荷计算结果确定污染流失潜力较大的关键区域,重点对其进行污染负荷控制,实现多雨城市排水环境非点源污染负荷控制。
When the current method is used to control the non-point source load of urban drainage environment,the calculated non-point source pollution load does not match the actual situation.The concentration of the controlled pollutants in the rainfall environment is not significantly reduced,and the calculation accuracy is low and the validity is poor.The problem.A non-point source pollution load control method for rainy urban drainage environment is proposed.The non-point source pollution load model is constructed by the storm water management model,the runoff curve numerical equation,the soil loss equation and the output coefficient model,and the simple method and the output coefficient method are used to measure the non-point.The source pollution load model is solved.Multi-factor comprehensive analysis method combined with non-point source pollution load calculation results to determine the key areas with large potential for pollution loss,focus on pollution load control,and achieve non-point source pollution load control in rainy urban drainage environment.
