Waste water valve control method and device, water purification equipment and storage medium

Abstract

The invention relates to the technical field of water purification equipment, and particularly relates to a waste water valve control method and device, water purification equipment and a storage medium. The control method of the waste water valve comprises the following steps: acquiring actual water quality information; determining the number of opened waste water holes and/or the overflowing area of the waste water holes according to the actual water quality information; and enabling the corresponding waste water holes to be opened according to the opening number and/or the overflowing area so as to adjust a waste water ratio. The opening number of the waste water holes and/or the overflowing area of the waste water holes are determined according to the actual water quality information, opening of the corresponding waste water holes is controlled according to the opening number of the waste water holes and/or the overflowing area of the waste water holes, then the waste water ratio is adjusted, different waste water ratios are achieved, and the method can adapt to water quality differences of different areas; and a RO membrane can reach a normal service life in areas with poor water quality, and the utilization rate of pure water can be improved in the areas with good water quality.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a control method for a waste water valve, a control device, water purification equipment and a storage medium. Background technique [0002] Due to the differences in the composition of groundwater quality, there are differences in water quality across the country. At present, the wastewater ratio of the water purifier is fixed, which cannot adapt to the differences in water quality across the country, which leads to the failure of the RO membrane to achieve normal life in areas with poor water quality and rapid pollution failure; while in places with good water quality, the same wastewater ratio is also There will be too much waste of fresh water resources. Contents of the invention [0003] The main purpose of the present invention is to provide a control method, control device, water purification equipment and storage medium of a waste water valve, so a...
