A drainage method, electronic equipment and controller for the drainage method

Abstract

The present invention provides a base drainage method, the method includes receiving the identification instruction of the current period: when the identification instruction is the first identification instruction, respectively controlling the opening of the first water conservancy switch and the opening of the second water conservancy switch; or controlling the first water conservancy switch off, the second water conservancy switch off, and the third water conservancy switch on; when the identification instruction is the second identification instruction, control the first water conservancy switch off, the third water conservancy switch off and the second water conservancy switch on; when the identification instruction is the third identification When commanded, the first water control switch is controlled to be turned on, the second water control switch is turned off, and the third water control switch is turned off. The present invention reduces the treatment pressure of the treatment facility during the rainy period, improves its service life and reduces the waste of resources; and avoids the technical defect of the river channel drying up when the sewage is only treated and discharged during the non-rainy period, achieving The technical effect of timely replenishment of river water.

Description

technical field [0001] The invention belongs to the technical field of municipal drainage, and particularly relates to a drainage method, electronic equipment and a controller for the drainage method. Background technique [0002] The municipal drainage system of the city is mainly divided into the combined drainage system and the divided drainage system. The earliest combined drainage system is to mix sewage, industrial waste water and rainwater in the same pipeline, and directly discharge it into the water body without any treatment, which is easy to seriously pollute the receiving water body. A segregated drainage system is a system that drains domestic sewage, industrial wastewater and rainwater in two or more separate pipes. [0003] At present, most of the existing municipal drainage technologies have the following problems: [0004] In rainy days, the rainwater is divided into the first rain and the middle and later rain according to the time method, the water quali...

AI Technical Summary

Problems solved by technology

[0004] In rainy days, the rainwater is divided into early rain and middle and late rain according to the time length method, water quality method, or liquid level method. For the discharge method of the first rain, the first rain is generally diverted directly to the municipal sewage pipe , after being treated by the sewage treatment plant and then reused. However, the sewage pipe has a limited transmission capacity and cannot accommodate a large amount of mixed water of sewage and rainwater. When the mixed water of rain is sent to the sewage treatment plant for treatment due to the large amount, it will also cause insufficient capacity of the sewage treatment plant or waste of treatment resources; The treatment discharge only involves domestic sewage. In this way, due to the insufficient discharge of water treatment in long-term sunny days, it is easy to cause no water replenishment along the river, and the river will dry up.

[0005] It can be seen that in the existing municipal drainage technology, the treatment pressure of the treatment facilities is very high for the treatment and discharge of rainwater in rainy days, and the treatment facilities are overloaded, which reduces the service life of the treatment facilities. Due to the insufficient discharge of water treatment, it is very easy to cause no water replenishment along the river, and the technical defect of river drying occurs.
