Pollution discharge flow-limiting well for automatically dredging corner of sewage pipe network and automatic dredging method of sewage discharge flow-limiting well
The invention discloses a sewage discharge flow-limiting well for automatic dredging at a sewage pipe network corner and an automatic dredging method thereof. The sewage discharge flow-limiting well comprises a well body, a sewage inlet pipeline, a sewage outlet pipeline and an overflow pipeline, wherein the sewage inlet pipeline, the sewage outlet pipeline and the overflow pipeline are connected with the well body; a desilting module, a flow limiting module and an overflow module are arranged in the well body; the desilting module is used for conveying sediments brought in from the upstream to the downstream and preventing the sediments from being deposited in the well body; the flow limiting module is arranged in a sewage outlet pipeline and used for intercepting dry season sewage and initial rainwater and preventing water impact of a sewage plant caused by the fact that excessive rainwater enters a sewage pipe network in the rainy season. And the overflow module is arranged in the overflow pipeline and is used for discharging surface water with less dirt content in the rainy season. According to the method, the inspection well at the corner of the sewage pipe network is transformed by utilizing transverse circulation generated at the corner of the sewage pipe network and simultaneously installing a rotational flow limiting valve. The problems of sediment deposition and large water inflow of a sewage plant in rainy seasons in a traditional sewage pipe network are solved.
本发明公开了污水管网转角处自动清淤的排污限流井及其自动清淤方法，该排污限流井包括井体和与其连接的污水进水管道、污水出水管道和溢流管道；井体内设置有清淤模块、限流模块和溢流模块；清淤模块用于将上游带入的沉积物输送至下游，防止在井体中淤积；限流模块设置在污水出水管道中，用于截留旱季污水与初期雨水，防止雨季因过多的雨水进入污水管网造成的污水厂的水量冲击；溢流模块设置在溢流管道中，用于将雨季含污量较少的表层水排出。该方法利用污水管网转角处产生的横向环流，同时安装旋流限流阀方式来改造污水管网转角处的检查井。本发明解决了传统污水管网存在的沉积物淤积与雨季污水厂进水量大问题。
