摘要
通过收集济南城区代表性样点的降雨径流水样，分析了济南城区道路和屋面雨水径流中的COD、SS及TN等污染指标的浓度及输出特征变化规律及其主要影响因素．结果表明，济南城区雨水径流污染负荷水平较高，初期径流污染严重，主要是有机污染物污染和悬浮物固体污染，污染物浓度随降雨历时呈现规律性变化，并随下垫面以及周围环境的不同而存在一定差异．掌握城区降雨径流污染特征对合理开展径流污染控制和有效利用城区雨水资源提供依据．
In order to study the concentration of pollutants such as COD, SS and TN etc, out - put characteristics and the main factors of them in the rainfall - runoff and the roof - runoff in Jinan urban area, we studied in Jinan urban area, through the collection of representative samples of the rainfall - runoff water samples. The results showed that the pollution load of the rainfall in Jinan urban area reached a high level. The initial run - off pollution is serious, and the mainly pollution are organic pollutants and suspended solids pollution. The concentration of pollutants changes with rainfall duration regularly, and there are certain difference with different surface. It provides the basis for the reasonable development of the control of the run - off pollution and effective use of rainwater resources to grasp the characteristics of urban rainfall- runoff pollution.
