弃流装置在合流制溢流污染控制中的研究进展

Research progress of rainwater split-flow device in combined sewer overflow control

合流制溢流污染已成为现阶段海绵城市建设、黑臭水体整治以及城市水景观构建过程中不可忽视且亟需解决的难题之一。初期雨水弃流装置作为一种削减入河污染负荷、收集利用雨水资源的工程设施,在合流制溢流污染控制中发挥着巨大的作用。介绍了雨水弃流装置的类型、处理效果、优缺点及适用性等,电控智能弃流井目前应用中存在的主要问题是雨水弃流中监测水质参数的选取和实时监测装置的设计,提出了智能弃流井的改进方案、注意事项等,以备相关从事人员或讨论参考。

Combined sewer overflow pollution has become one of the most important and urgent problems in sponge city construction,black and odorous water treatment and urban water landscape construction.As an engineering facility to reduce pollution load and collect and utilize rainwater resources,the initial rainwater split-flow device plays an important role in pollution control of combined sewer overflow.This paper introduced the types,treatment effects,advantages,disadvantages and applicability of rainwater split-flow devices.The main problems existing in the application of electronic control intelligent abandonment wells were the selection of monitoring water quality parameters in rainwater abandonment and the design of real-time monitoring device.The improvement scheme and matters needing attention of intelligent abandonment wells were put forward for reference and discussion by relevant engineers.
