Water treatment system and water purification equipment

Abstract

The invention discloses a water treatment system and water purification equipment. The water treatment system comprises a reverse osmosis membrane filter element with a raw water end, a pure water endand a concentrated water end; the raw water end is communicated with a raw water tank for containing raw water through a first pipeline; the pure water end is connected with a second pipeline communicated with the raw water tank and a third pipeline of which the tail end is a pure water outlet; and the system further comprises a control valve used for controlling the third pipeline and the secondpipeline to be alternately communicated. Due to the above structure, firstly, when a user takes a first cup of water, pure water permeated by concentrated water at the pure water end of the reverse osmosis membrane filter element flows into the second pipeline through the control valve to enter the raw water tank, the problem that the TDS value of the first cup of water is high is well solved, and meanwhile waste of water resources is avoided.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a water treatment system and water purification equipment. Background technique [0002] In recent years, with people's emphasis on personal health, household water purification equipment has become very popular in the market. And more common in existing household water purification equipment is the reverse osmosis water purifier that filter material is reverse osmosis membrane (RO). The working principle of the reverse osmosis water purifier is that the raw water passes through the reverse osmosis membrane filter element, and the water molecules pass through the reverse osmosis membrane through pressurization, while the inorganic salt ions, organic matter, colloid, bacteria, viruses, etc. are intercepted by the reverse osmosis membrane and discharged with the concentrated water , so as to achieve the purpose of purifying water. [0003] When the reverse os...
