An interception well system and its control method for diversion pipe network

Abstract

The invention discloses a separate system pipe network catch basin system and a control method thereof. The system comprises a basin body and a control unit, wherein a first rain closure pipe, a dreg buoy and a multilevel adjustable overflow board are arranged on the lateral wall of the basin body from left to right; the first rain closure pipe is arranged at the bottom of the lateral wall of the basin body, and is provided with an electric closure check valve; the dreg buoy and the multilevel adjustable overflow board are arranged on a runner of the basin body; a liquid level sensor and a water quality sensor are arranged inside the basin body at the left side of the multilevel adjustable overflow board; a signal output end of the liquid level sensor and a signal output end of the water quality sensor are respectively connected with a control signal input end of the control unit; a control signal output end of the control unit is respectively connected with the electric closure check valve and the multilevel adjustable overflow board. According to the control method provided by the invention, a first rain range is practically defined by a runoff volume angle of the first rain; the control unit uses liquid level signals and rain quality signals inside the catch basin to control a valve on the first rain closure pipe to open and close, so that the first rain can be effectively and accurately closured in the separate system pipe network catch basin system.

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...
