Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

[0016] The intercepting well drainage control method of the present invention, the intercepting well includes a well body, the front end of the well body is provided with a water inlet pipe, the end of the well body is provided with a drainage pipe connected to a natural water body, and the side wall of the well body is provided with a sewage pipe connected to a sewage treatment plant. tube, also includes the following steps:

[0017] Step 1, when the rainfall is zero, control the interception of the sewage in the interception well to the sewage pipe, and stop the drainage to the drainage pipe at the same time, and the sewage flows to the sewage treatment plant for treatment;

[0018] Step 2, when the rainfall is greater than zero...

Abstract

The invention discloses a drainage control method of a catch basin. The method comprises the following steps: 1, when rainfall is zero, controlling sewage in the catch basin to be intercepted to a sewage pipe, and stopping draining to a drain pipe at the same time; 2, when the rainfall is greater than zero, detecting the concentration of pollutant in rainwater in the catch basin in real time from the beginning of rainfall until the concentration of the pollutant is detected to be less than a set value at a certain time t, and judging the rainwater within a period from the beginning of rainfall to the time t to be initial rainwater; 3, controlling the initial rainwater in the catch basin to be intercepted to the sewage pipe at the period from the beginning of rainfall to the time t; controlling the catch basin to stop draining to the sewage pipe at the time exceeding the time t, and controlling the rainwater to be discharged into the drain pipe. The drainage control method can be used for controlling dry flow sewage and the initial rainwater with higher pollutant concentration to be intercepted to the sewage pipe, thus avoiding the pollution to natural water; furthermore, the liquid level in the catch basin is detected in real time; when the liquid level exceeds a warning water level, the method can control the catch basin to naturally discharge the rainwater while intercepting the rainwater, thus avoiding waterlogging of a city.

Description

technical field [0001] The invention belongs to the technical field of water supply and drainage, and in particular relates to a drainage control method for an interception well. Background technique [0002] In the combined pipeline system in urban drainage projects in our country, interception wells have existed for a long time. However, the previous interception wells had simple functions and could not realize functions such as controlling the sewage flow of sewage pipes, identifying early rain, and safely discharging floods. Contents of the invention [0003] The object of the present invention is to provide a drainage control method for intercepting wells in order to solve the above-mentioned deficiencies in the background technology. [0004] The technical solution adopted in the present invention is: a drainage control method for an intercepting well, the intercepting well includes a well body, the front end of the well body is provided with a water inlet pipe, the...
