摘要
降雨事件统计对污水干线收集系统的设计规划、运行管理具有重要参考意义。文中利用某污水干线收集系统范围内代表性泵站的降雨量数据,借助降雨分区统计方法,将2015年1月~2017年9月该污水干线总管运行的降雨事件进行分类统计。选取其中一日该污水干线总管服务范围内各代表性泵站的降雨数据进行分析,结果表明本统计分析方法对于当日的降雨分类准确。将统计分析结果与该污水干线总管末端出口泵站的运行数据结合,计算出不同降雨事件等级下出口泵站的日均流量,为污水干线总管设计规划提供参考。
The rainfall event statisticsare of referential value for the desig,plan,operation and management of trunk sewer system.In this study,the rainfall events during 2015.01-2017.09 were classifiedbased on the rainfall data of representative pump stations within a trunk sewer system in virtue of the rainfallregionalization statistical method.The one-day rainfall dataof representative pump stations within the service area of the trunk sewer systemwas extracted and analyzed,and the results indicated that this statistical analysis method was correct.Combined the statistical analysis results with the average daily flow of theoutfall pump station of the trunk sewer system,the average daily flow of outfall pump station under different rainfall events were obtained,which provided reference for the design and plan of trunk sewer system.
