在城市合流制区域晴天污水得到完全收集的前提下，控制 合适频次的降雨不溢流成为控制溢流污染的关键。为此，武汉市规划研究院将《城市合流区污水溢流污染控制标准研究》列入2018年院自主科研项目。通过分析武汉市降雨数据得出了日降雨量、小时降雨强度与合流制排口年溢流频次的关系，进而提出了降雨溢流场次控制率概念，建立了降雨溢流场次控制率与小时降雨强度的量化关系。根据武汉市本地降雨特征，提出了不同降雨溢流场次控制率对应的3 h短历时降雨过程线，通过将雨型数据代入排水管网数学模型，获得了不同溢流场次控制率与其实现的溢流污染物削减率之间的量化关系。

Under the premise that the sewage in the urban combined sewer system in dry weather is completely collected, the key to control the overflow pollution is to determine appropriate frequency of rainfall without overflow. For this purpose ， Wuhan Planning ＆ Design Institute listed the “Study on the Control Standards for Sewage Overflow Pollution in Urban Combined Sewer System Area” into the independent research project of the institute in 2018. Based on the analysis of Wuhan rainfall data, the relationship between daily rainfall, hourly rainfall intensity and the annual overflow frequency of the combined sewer system was obtained. Then, the concept of rainfall overflow frequency control rate was proposed. The quantitative relationship between the rainfall overflow frequency control rate and the hourly rainfall intensity was established as well. Based on the characteristics of local rainfall in Wuhan, a three-hour short-duration hyetograph corresponding to different rainfall overflow frequency control rates was put forward. By the calculation of the mathematical model of the drainage network with the rain-type data, the quantitative relationship between the different overflow control rates and the overflow pollutant reduction rates could be achieved.?
