Unpowered sewage interception and anti-backflow system
The invention discloses an unpowered sewage interception and anti-backflow system. The unpowered sewage interception and anti-backflow system comprises a sewage well as well as a flood-discharge waterdrainage port and a sewage-interception water drainage port which are arranged in the sewage well, wherein the vertical height of the sewage-interception water drainage port in the sewage well is lower than that of the flood-discharge water drainage port; a duckbill valve is connected with the other end of a flood-discharge water drainage port communication pipe; the sewage-interception water drainage port communicates with a water intake pipe of an unpowered flow interception valve; a water outlet of the unpowered flow interception valve communicates with a sewage treatment pipe network through a connecting pipe; the unpowered flow interception valve is composed of a drum-type tank body, the water intake pipe, an air intake pipe assembly and a water drainage pipe; the water intake pipe is fixedly arranged on the side wall of the tank body and communicates with the inner cavity of the tank body; the air intake pipe assembly and the water drainage pipe are correspondingly arranged at the upper and lower ends of the tank body; and the water intake pipe is tangent to the tank body. In the unpowered sewage interception and anti-backflow system, simple equipment is adopted; no externaldriving force is needed; through the flow limiting operation of the unpowered flow interception valve, the circumstance that a lot of rain and sewage are mixed with water, flow into the sewage treatment pipe network, and impact a treatment plant can be prevented; the overall structure is compact; the failure rate is low; the practicability is high; the cost is low; and the unpowered sewage interception and anti-backflow system is suitable for popularization and use.
本发明公开了一种无动力截污、防倒灌系统，包括污水井以及设置于污水井内的行洪排水口和截污排水口，且截污排水口在污水井内的垂直高度低于行洪排水口，所述行洪排水口连通管道的另一端连接有鸭嘴阀，所述截污排水口与无动力截流阀的进水管连通，且无动力截流阀的出水口通过接管与污水处理管网连通；所述无动力截流阀是由鼓状的罐体、固定设置于罐体侧壁且与罐体内腔连通的进水管以及设置于罐体的上下端分别设置有进气管组件和排水管构成，且进水管与罐体相切。该系统，设备简单，无需外设驱动力，通过无动力截流阀限流避免大量雨污混合水流入污水处理管网对处理厂造成冲击，整体结构紧凑，故障率低，实用性强，成本低廉，适合推广使用。
