Combined system overflow pollution control system and treatment method thereof
The invention discloses a combined system overflow pollution control system and a treatment method thereof, the combined system overflow pollution control system is characterized in that an overflow port of a catch basin is provided with a duckbill valve, a rear sewage pipeline of the duckbill valve is provided with a first water quality on-line monitor and a three-way valve, the three-way valve is provided with two pipelines, and the two pipelines are respectively a hydraulic rotary screen water inlet pipe and a surpassing pipeline; the water outlet end of the surpassing pipeline is connected to a river channel; the water inlet end of the hydraulic screen is connected to the three-way valve, and the water outlet end is connected to the sand settling chamber through a sewage pipe; the inner ring of the grit settling chamber is a grit chamber, the outer ring of the grit settling chamber is a settling tank, and a retaining wall bottom hole for sewage circulation is formed between the grit chamber and the settling tank; the biological rotating disc is connected with the sand settling chamber through a biological rotating disc water inlet pipe. The system is simple, convenient to operate, short in starting time, accurate in control, free of aeration and sludge backflow, low in operation cost, high in treatment efficiency, capable of reducing pollution of combined overflow to river water and capable of achieving a side treatment effect on the river water.
本发明公开了一种合流制溢流污染控制系统及其处理方法，包括截流井的溢流口设置有鸭嘴阀，且鸭嘴阀的后污水管线设置有第一水质在线监测仪和三通阀，三通阀设置有两条管线，两条管线分别是水力旋转筛网进水管和超越管线，且超越管线的出水端连接于河道；水力筛网的进水端连接于三通阀，且出水端通过污水管连接于沉砂沉淀室；沉砂沉淀室的内圈为沉砂池，外圈为沉淀池，沉砂池与沉淀池之间设置有用于污水流通的挡墙底部孔隙；生物转盘通过生物转盘进水管与沉砂沉淀室连接。本发明系统简单、操作方便，启动时间快，控制精确，不需要曝气和污泥回流，运营成本低，处理效率高，能够减少合流制溢流对河水的污染，并能够对河水起到旁侧处理效果。
