分流制排水系统中组合式初雨调蓄池的设计与优化

分流制排水系统雨水径流排湖对水体生态环境的破坏日益严重,建设调蓄池截流污染较重的初期雨水逐渐受到重视和应用。结合武汉某初期雨水调蓄池设计实例,介绍了分流制系统中调蓄池有效容积计算方法、组合式初雨调蓄池布置形式。通过优化冲洗系统、巡视通道及采光井的设计改善了调蓄池后期运维中的节能效果及便捷性,可为分流制排水系统中初雨调蓄池的设计提供参考。

Design and Optimization of Combined Initial Rainwater Storage Tank in Separate Drainage System

Because rainwater runoff discharging into the lake in the separate drainage system has caused more and more serious damage to the ecological environment of water body,the construction of storage tank to intercept the initial rainwater with heavy pollution has been paid more and more attention and applied.Combined with an example of the design of an initial rainwater storage tank in Wuhan,the effective volume calculation method of the storage tank and the arrangement form of the combined initial rainwater storage tank in the separate system was introduced.Furthermore,the energy-saving effect and operating convenience got improved by the optimization of design of flushing system,patrol channel and light well,which could provide reference for application of initial rainwater storage tank in separate drainage system.
