摘　　要：通过对我国北方某大型城市典型再生水补给型河道开展汛期连续水质监测,对排水系统在降雨期间雨水径流及合流制溢流污染的指标特点、排放路径及变化规律进行研究。研究结果表明合流制溢流及雨水径流污染是汛期入河污染物的主要来源,根据其污染物特征、随时间变化特点以及各类污染物之间的相关性制定相对应的污染物控制策略,通过充分发挥城市排水系统的一体化运营管理优势,有效减少汛期入河污染物总量,提升河道水环境质量。Based on the continuous water quality monitoring of typical reclaimed water recharge rivers in a large city of Northern China during wet weather,the index characteristics,emission path and variation law of rainwater runoff and combined overflow pollution of drainage system during rainfall were studied.The results show that the combined overflow and rainwater runoff pollution are the main sources of pollutants entering the river during rainfall.According to the characteristics of pollutants,time-varying characteristics and the correlation between various pollutants,the corresponding pollutant control strategies are formulated.By giving full play to the advantages of urban drainage system integrated operation,the total amount of pollutants entering the river during rainfall can be effectively reduced and the quality of river water environment can be improved.
