Overflow pollution control and backflow prevention system
The invention discloses an overflow pollution control and anti-backflow system which comprises a water inlet pipe, a grating well, a first water outlet pipe, a sewage intercepting well, a fifth water outlet pipe and an anti-backflow device. The water inlet pipe is arranged on one side of the grating well, the grating well is communicated with the sewage intercepting well through the first water outlet pipe, the fifth water outlet pipe is arranged on one side of the sewage intercepting well, and the anti-backflow device is arranged in the fifth water drainage pipe. A sewage discharging device communicated with a current sewage system is arranged in the sewage intercepting well. Under the cooperation of the sewage discharge device, the fifth water outlet pipe and the anti-backflow device, the sewage interception amount can be accurately controlled in rainy days, the phenomenon that the anti-backflow effect of a flap valve or a duckbill valve in the prior art fails is avoided, implementation is easy, the manufacturing cost is low, management is convenient, and therefore the sewage treatment efficiency is improved, and the water environment quality is improved.
本发明公开了一种溢流污染控制及防倒灌系统，包括进水管、格栅井、第一出水管、截污井、第五出水管以及防倒灌器。所述进水管设置于所述格栅井的一侧，所述格栅井通过所述第一出水管与所述截污井相连通，在所述截污井的一侧设置所述第五出水管，所述防倒灌器设置于所述第五排水管的内部，所述截污井的内部设置有与现状污水系统连通的排污装置。本发明在排污装置、第五出水管及防倒灌器的配合下，在雨天不仅能精确控制截污量，避免了现有技术中拍门或者鸭嘴阀防倒灌作用失灵的现象发生，还易于实施、造价低及便于管理，从而实现污水处理效能的提升及水环境质量的改善。
