Water draining method, electronic device used for water draining method and controller

Abstract

The invention provides a water draining method. The method comprises the steps of receiving a recognition instruction at a current period; when the recognition instruction is a first recognition instruction, controlling a first water conservancy switch to be opened and a second water conservancy switch to be opened; or controlling the first water conservancy switch to be closed, the second water conservancy switch to be closed and a third water conservancy switch to be opened; when the recognition instruction is a second recognition instruction, controlling the first water conservancy switch to be closed, the third water conservancy switch to be closed and the second water conservancy switch to be opened; and when the recognition instruction is a third recognition instruction, controllingthe first water conservancy switch to be opened, the second water conservancy switch to be closed and the third water conservancy switch to be closed. The treatment pressure of a treatment facility atthe rainfall period can be reduced, the service life of the facility is prolonged, resource waste is reduced, at the non-rainfall period, the technical defect that when the sewage is treated and drained, a riverway is dried up can be overcome, and the technical effect of river water in-time supplementing can be achieved.

Description

technical field [0001] The invention belongs to the technical field of municipal drainage, and in particular relates to a drainage method, electronic equipment and a controller used in the drainage method. Background technique [0002] The city's municipal drainage system is mainly divided into combined drainage system and divergent drainage system. The earliest combined drainage system is to mix sewage, industrial wastewater and rainwater in the same pipe, and discharge them directly into the nearby water body without any treatment, which will easily cause serious pollution to the receiving water body. The diversion drainage system is a system that discharges domestic sewage, industrial wastewater and rainwater in two or more independent pipelines. [0003] At present, most of the existing municipal drainage technologies have the following problems: [0004] In rainy days, the rainwater is divided into early rain and middle and late rain according to the time length metho...

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.
