The invention provides a water purification control method and device and water purification equipment, a pure water flow adjusting device is arranged on a pure water branch of the water purification equipment, and the method comprises the following steps: obtaining the current concentrated water flow and the historical total concentrated water flow on a concentrated water branch of a reverse osmosis membrane filter element of the water purification equipment; calculating the current total concentrated water flow based on the preset standard concentrated water flow, the rising coefficient of the concentrated water flow, the current concentrated water flow and the historical total concentrated water flow; based on the relation between the current total concentrated water flow and the set total concentrated water flow, the pure water generation flow of the pure water flow adjusting device is adjusted. The total concentrated water flow is calculated in real time by monitoring the current concentrated water flow and the historical total concentrated water flow on the concentrated water branch of the reverse osmosis membrane filter element, and the pure water generation flow of the pure water flow adjusting device is adjusted in real time based on the total concentrated water flow, so that the self-adaptive adjustment of the recovery rate of the water purification equipment along with the water quality change condition is realized; while water resources are saved, the problem of blockage of the reverse osmosis membrane filter element is avoided, and the use experience of a user is improved.
Description
technical field [0001] The invention relates to the technical field of water purification, in particular to a water purification control method, device and water purification equipment. Background technique [0002] Reverse osmosis water purifiers are popular for their ability to effectively remove many types of pollutants from tap water. At present, the reverse osmosis water purifiers on the market usually have adjusted the proportional valve of the reverse osmosis membrane before leaving the factory or during installation. During the use of the water purifier, the proportional valve remains unchanged, that is, the proportional valve of the corresponding water purifier. The water flow out of the valve is also a fixed value. Due to the great difference in water quality in different regions and different seasons in the same region, the same water purifier will easily clog the reverse osmosis membrane filter in regions with poor water quality, and waste water resources in reg...
