Combined system pipe network intercepting well system and control method thereof

Abstract

The invention provides a combined system pipe network intercepting well system and a control method thereof. The system comprises a well body and a control unit, wherein a well body runner is provided with a first rain overflow weir. a slag blocking float bowl and a multi-level adjustable overflow plate, wherein the bottom of a side wall between a water inlet pipe and the first rain overflow weir is provided with a sewage intercepting pipe; a first rain intercepting pipe is arranged between the first rain overflow weir and the multi-level adjustable overflow plate; the sewage intercepting pipe is provided with a first electric stop-check valve; the first rain intercepting tube is provided with a second electric stop-check valve; the left side of the first rain overflow weir is provided with a liquid level sensor and a water quality sensor; the signal output ends of the liquid level sensor and the water quality sensor are respectively connected with the control signal input end of a control unit; the control unit is respectively connected with the first electric stop-check valve, the second electric stop-check valve and the multi-level adjustable overflow plate. According to the control method, first rain is practically defined from the aspect of first rain runoff volume; liquid level and water quality signals are used for controlling the opening and closing of valves on the sewage intercepting pipe and the first rain intercepting pipe, so that accurate first rain intercepting is realized.

Description

technical field [0001] The invention relates to a drainage pipe network system, in particular to a combined pipe network interception well system and a control method thereof. Background technique [0002] With the increase of urban air pollution and ground pollution, the pollution of rainwater runoff is becoming more and more serious, especially the initial rainwater with more pollutants (referred to as primary rain). It is used in typical urban domestic sewage, so it is very necessary to collect and treat the first rain. At present, in the drainage system, the initial rain is intercepted in the interception well, and then the initial rain is transported to the sewage treatment plant. However, in the process of intercepting the initial rain, how to accurately measure the initial rain has always been a problem. The difficulty is that it is still in the vague and extensive measurement stage. Contents of the invention [0003] The purpose of the present invention is to pro...
