摘　　要：为了能够在复杂城市区域内快速了解城市河道溢流污染规律和整体估算污染量,提出了以监测数据为基础、以封闭区域为整体的计算方法:利用区域内污水量、雨水进入污水系统的水量、水厂处理水量以及溢流水量四者之间的平衡关系,结合污染物浓度变化、水量变化监测数据对溢流污染量进行计算,并对应降雨数据总结溢流规律。结果表明,根据458 d期间发生的60场次降雨实测数据、流量水质监测数据作为试算基础,计算所得结果与监测结果偏差了+11.7%,结果准确性尚可。该方法无需关注区域内部复杂的雨污管网情况,计算分析较为快速,具有一定准确度,能够为水环境规划、河道水环境工程的前期阶段提供支撑。To quickly investigate the overflow pollution pattern of urban rivers and to estimate the total pollution amount in complex urban areas,a calculation method based on monitoring data is proposed,which considers a closed region as a whole:Based on the balance relationship between domestic sewage volume,rainwater volume entering the sewage system,treated volume of the wastewater treatment plant,and overflow volume in the region,the overflow pollution is calculated by combining the monitoring data of pollutant concentration and flow,and further used to summarize the overflow pattern according to the rainfall data.The results show that based on 60 rainfall data,flow and water quality monitoring data during 458 days,the deviation between the calculated results and the monitoring results is+11.7%,and the accuracy of the results is acceptable.This method does not need to pay attention to the complex drainage network in the region,and the calculation and analysis is fast and reliable to support water environment planning and early stage of river water environment engineering.
