清污分流系统在污水收集提质增效中的应用研究

Research on Application of Water-Sewage Diversion System in Sewage Collection to Improve Quality and Efficiency

通过对城镇现有排水现状的研究发现,除管网系统结构性缺陷修复外,污水收集提质增效还存在管网的混接改造、合流截流设施改造、合流箱涵"挤外水"以及排水口防倒灌等难题。通过开辟污水通道并在管网的适当节点设置智能分流井,将大型排水口的汇水范围减小到1公顷以下,使其出水具有初雨效应,构建清污分流系统,可以彻底解决以上难题。

Through the research on the current drainage situation in cities and towns,in addition to the repair of structural defects in the pipe network system,there are also difficulties in sewage collection,such as,mixing transformation of pipeline network,renovation of confluence and interception facilities,"squeezing the external water"of the confluence box culvert,and preventing the backflow of the drainage outlet.By opening up sewage channels and setting up intelligent diversion wells at appropriate nodes of the pipe network,the catchment area of large drainage outlets is reduced to less than 1 hectare to make the effluent have an initial rain effect and build a sewage diversion system,which can solve the above problems.
