摘 要: 随着广州市中心城区河道水环境治理力度的加大,合流制溢流污染问题越来越突出,对城市河道水体构成了日益严重的威胁。本文选取广州市中心城区典型合流制排水口进行了18场降雨的径流污染监测,总结了在典型小雨、典型中雨及典型大雨场次下排水口各水质指标随降雨历时的变化规律,同时分析了18场降雨的排水口最高浓度、平均浓度与总降雨量的关系,研究成果可为合流制污染控制工程的设计提供参考。 Along with the strength enhancement of the improvement of the river channel water environment in the central urban area of Guangzhou, the problem of the overflow pollution from the combined sewer system becomes more and more prominent, thus constitutes an increasingly serious threat to the water in the urban river. An outlet of the typical combined sewer system in the central urban area of Guangzhou is selected herein for monitoring the runoff pollution from 18 rainfall events; from which the law of the change of all the water quality indexes at the outlet along with the duration of rainfall for the events of the typical light rain, moderate rain and heavy rain is summarized herein, meanwhile, the relationship of the maximum pollution concentration and the mean pollution concentration with the total rainfall is analyzed as well. This study achievement can provide references for the design of the pollution control project of the combined sewer system.
