Water purifier, water purification system and water quality adjusting method

Abstract

The invention discloses a water purifier, a water purification system and a water quality adjusting method. The water purification system comprises a water inlet channel, a filtering channel, a water outlet channel, a waste water channel, a booster pump and a regulating valve. A front filter element, a composite filter element and a rear filter element are sequentially connected in series on the filter channel, the composite filter element comprises at least two filter element units which are connected in parallel, the desalting rates of the at least two filter element units are different, a regulating valve is arranged at a water outlet of at least one of the at least two filter element units, and the regulating valve is communicated with the filter element units. The opening degree of the adjusting valve is adjustable, and the adjusting valve is suitable for adjusting the flow of the corresponding filter element unit. According to the water purification system provided by the invention, the adjusting valve with the adjustable opening degree is arranged on the filter element unit, and the opening degree of the adjusting valve is adjusted, so that the preset desalting rate requirement of the water outlet end of the water purification system can be met, a water tank structure for mixing water with different desalting rates is not required to be arranged, and under the preset desalting rate requirement, the desalting rate of the water outlet end of the water purification system is greatly improved. Real-time control and real-time water production can be realized, so that the water production efficiency of the water purification system can be improved.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a water purifier, a water purification system and a water quality adjustment method. Background technique [0002] At present, the water purification system is mostly reverse osmosis water purifier or nanofiltration water purifier. The desalination rate of the osmotic water purifier is above 95%, which can be defined as a pure water machine. The rate is above 40%, and the effluent retains a certain amount of minerals. The water quality of the above two water purifiers is fixed and single, and cannot meet the water demand of some water use scenarios in the user's life at the same time. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a water purifier, a water purification system, and a water quality adjustment method to so...
