Interceptor well system and its control method for split flow pipe network

Abstract

The invention discloses a separated pipe network catch basin system and a control method thereof. The system comprises a well body and a control unit; the side wall of the well body is provided with a first rain interceptor, a slag blocking buoy and a plurality of stages of adjustable overflow plates from left to right; the first rain interceptor is arranged at the bottom of the side wall of the well body and is provided with an electric stop-check valve; the slag blocking buoy and the plurality of stages of adjustable overflow plates are arranged on a flow passage of the well body; a liquid level sensor is arranged in the well body; a rainfall sensor is arranged outside the well body; the signal output ends of the liquid level sensor and the rainfall sensor are respectively connected with the control signal input end of the control unit; and the control signal output end of the control unit is respectively connected with the electric stop-check valve and the plurality of stages of adjustable overflow plates. The control method carries out practical defining on a first rain range from the angle of a runoff volume of initial rainwater and the control unit utilizes a liquid level signal in a catch basin and a rainfall signal outside the catch basin to control opening and closing of the valve on the first rain interceptor, so that accurate interception on first rain is effectively implemented in the separated pipe network catch basin.

Description

technical field [0001] The invention relates to a drainage pipe network system, in particular to a diversion system 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 i...
