Rain and sewage diversion well and diversion method
The invention provides a rain and sewage diversion well which comprises a first well cavity, a second well cavity and a third well cavity, the well bottom of the second well cavity is flush with the first well cavity, the well bottom of the third well cavity is higher than the second well cavity, the well bottom of the third well cavity is flush with the bottom of a downstream pipeline, and the two ends of the first well cavity are connected with a water inlet pipe and a water outlet pipe. A partition wall is arranged in the middle of the first well cavity and provided with a water outlet, a flexible cut-off device is installed between the water outlet and the water outlet pipe and used for opening and closing the water outlet, a communicated sewage pipe is arranged between the first well cavity and the second well cavity and located between the water inlet pipe and the water outlet, a submersible sewage pump is installed in the second well cavity, and a pressure pipe is connected to the submersible sewage pump. The tail end of the pressure pipe is connected with a sewage well pipe. The invention further provides a rainwater and sewage diversion method, sewage is effectively prevented from entering the rainwater drainage system, accurate rainwater and sewage separation is achieved, precipitation of pollutants carried by initial rainwater is facilitated, direct drainage of the pollutants along with the rainwater is reduced, and the treatment efficiency of the initial rainwater is improved.
本发明提供了一种雨污分流井，包括第一井腔、第二井腔及第三井腔，第二井腔的井底与第一井腔齐平，第三井腔的井底高于第二井腔，第三井腔的井底与下游管道的底部齐平，第一井腔的两端连接有进水管和出水管，第一井腔的中部设置有隔墙，隔墙设置有出水口，出水口与出水管之间安装有柔性截流装置，用于启闭出水口，第一井腔与第二井腔之间设置有连通的污水管，污水管位于进水管与出水口之间，第二井腔安装有潜污泵，潜污泵上连接有压力管，压力管的末端连接有污水井管。还提供了一种雨污分流方法，有效阻止污水进入雨水排放系统，实现精准的雨污分离，有助于初期雨水携带的污染物沉淀，减少污染物随雨水直接排放，提高了对初期雨水的处理效率。
