摘　　要：以邢台隆尧东方食品城雨水泵站为例,介绍大型雨水泵站设计规模和水泵机组配置的优化设计方法。基于鸿业暴雨排水及低影响开发模拟系统(HY-SWMM),构建雨水管网的水力模型,并采用传统推理法进行水力计算校核;水泵配置对比了大小泵搭配、高低液位启动、等差和不等差分集水池有效水深等方案。结果表明,采用模型法计算所得大汇水面积雨水泵站的设计规模较推理法可减少约20%;简单地将水泵流量按泵站规模均分、采用等差水位启动水泵是不科学的,需要采用大小泵搭配和适当高液位、不等差水位启动来避免水泵频繁启停。This paper introduced the optimization design method for determining the design scale and pump unit configuration of large rainwater pumping stations exemplified by Longyao Dongfang Food City rainwater pumping station in Xingtai.Based on Hongye storm water drainage and low impact development simulation system(HY-SWMM),the hydraulic model of rainwater pipe network was constructed,and the hydraulic calculation was verified by traditional inference method.The water pump configuration compared the schemes such as combination of large and small pumps,start-up at high and low water levels,and the effective water depth of sump with equal and unequal differences.The design scale of a rainwater pumping station with large catchment area calculated by model method was reduced by approximately 20%compared with that calculated by inference method.It is unscientific to simply divide the flow rate of the water pump according to the scale of the pumping station,and start the pump with equal differential water level.It is necessary to use the combination of large and small pumps and start-up with appropriate high water level and unequal differential water level to avoid frequent start-up and stop of the pump.
