摘　　要：工业建设项目用水主要为生产用水。应用海绵城市理念将雨水收集净化后用于生产,具有重要的生态和经济效益。结合某燃机电厂的工程案例论述电厂项目中海绵城市雨水排水系统的设计。通过雨水花园、植草沟、人工湿地等海绵设施的合理设置,并与全地下式雨水泵房有机结合,电厂年径流总量控制率达到77.5%,年径流固体悬浮物总削减率达到65.86%。既实现了削减径流、控制污染以及节水节能的综合效益,同时雨水泵房的全地下式设计兼顾了现代电厂去工业化的设计趋势。Sponge city concept is of great significance for control pollution and promoting water resource utilization in industrial area.Based on the example of a gas-turbine power plant in Zhuhai,how to apply the“sponge city”concept in rainwater drainage system design as for the area of power plants was discussed.Sponge facilities,including rainwater garden,grassed swale and constructed wetlands,were applied in this project,combined with the rainwater pump house built completely underground.With these engineering measures,the power plant’s volume capture ratio of annual runoff reaches 77.5%and suspended solids reduction rate by annual rainfall reaches 65.86%.The rainwater drainage system of power plants not only realizes the goal of reducing runoff flow,controlling pollution as well as saving water and energy,but also corresponds with the trend of deindustrialization of modern power plants.
