城市雨水径流面污染负荷的计算模型

Calculation Model for Area Source Pollution Load of Urban Rain Water Runoff

对城市雨水径流的污染负荷进行定量分析评价是制定控制策略和实施有效总量控制的基础,为此建立了一种计算城市径流面污染负荷的数学模型,它具有参数少、因果关系清楚、简便直接等特点。利用该模型可对城市径流非点源污染进行量化分析并合理确定初期雨水径流控制量,这为城市径流污染控制决策的制定提供了一种有效的分析方法。

Quantitative analysis on pollution load of urban runoff was a basis for working out control strategy and implementing effective control of total runoff.Therefore,a mathematic model was established for calculating area source pollution load of urban runoff,which was characterized by few parameters,clarified causality,and convenient for application.The model could be used for quantitative analysis on non-point pollution of urban runoff and rational determination of first flush split flow.It provided an effective analysis method for decision-making of pollution control of urban runoff.
