The invention relates to a water purifier recovery rate control method, device and system and a water purifier. A data acquisition device of the water purifier can be used for acquiring and sending water quality operation parameters in real time; a data processing host performs analysis according to the water quality operation parameters to obtain reverse osmosis membrane flow attenuation parameters, so that when the reverse osmosis membrane flow attenuation parameters do not meet preset attenuation conditions, the recovery rate of the water purifier is adjusted through the recovery rate control device. By means of the scheme, the attenuation degree of a reverse osmosis membrane filter element of the water purifier can be truly reflected in real time according to the water quality characteristics in the water purifier in the operation process of the water purifier, and then the recovery rate of the water purifier is adjusted to be in the state matched with the current water quality inreal time according to the attenuation degree of the reverse osmosis membrane filter element. Therefore, the water yield of the water purifier is guaranteed, scaling of a reverse osmosis membrane produced by the water purifier is avoided, waste of raw water can be effectively prevented, and high water purification reliability is achieved.
Description
technical field [0001] The present application relates to the technical field of water quality treatment, in particular to a water purifier recovery rate control method, device, system and water purifier. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people's requirements for drinking water quality are becoming more and more strict. More everywhere. In recent years, reverse osmosis membrane (Reverse Osmosis Membrane, RO membrane) water purifiers have been widely concerned in the water purification industry. This type of water purifier has been debugged before leaving the factory or during installation. After the purified water is compressed and passed through the RO membrane, when it becomes pure water and concentrated water, the ratio of pure water and concentrated water has been determined, and the recovery rate of the corresponding water purifier is also a fixed value. [0003] However, dur...
