Abstract

The invention relates to the technical field of water purification, in particular to a cleaning method, a cleaning device, a water purification system and a readable storage medium. The cleaning method is used for cleaning a fine filtration unit in the water purification system. The water purification system comprises a pretreatment unit, a fine filtration unit and a supercharging device arranged between the pretreatment unit and the fine filtration unit, wherein a concentrated water port of the filtering unit communicates with a waste water pipeline, and a flushing valve is arranged on the waste water pipeline. The cleaning method comprises the following steps: a first cleaning step: adjusting the output flow of the supercharging device to a first flow and conducting operation for a first preset time; and a second cleaning step: adjusting the output flow of the supercharging device to a second flow and conducting operation for a second preset time. When the first cleaning step is switched to the second cleaning step, the speed of water flow on a membrane surface of the fine filtering unit is disturbed, so the fine filtering unit can obtain a better washing effect, salt ions and scales deposited on the membrane surface can be stripped more easily, and washing effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a cleaning method, a cleaning device, a water purification system and a readable storage medium. Background technique [0002] At present, for conventional reverse osmosis water purifiers, as the amount of water filtered by the water purifier increases, pollutants and concentrated scaling will cause the blockage of the reverse osmosis membrane and reduce the water production rate. In order to delay the attenuation of the reverse osmosis membrane filter element, The conventional solution is to open the solenoid valve of the wastewater ratio of the reverse osmosis membrane filter element after filtering for a period of time or a certain amount of water purification, and the raw water flushes the membrane surface to reduce the concentration polarization. The effect is limited. Contents of the invention [0003] Therefore, the purpose of the present invention is to over...
