Embodiment Construction

[0025] In order to make those skilled in the art more clearly understand the purpose, technical solutions and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 As shown, a water purification system of an embodiment includes an advanced oxidation module 10 , an activated carbon module 20 and a reverse osmosis membrane module 30 .

[0027] Among them, the advanced oxidation module 10 is used for pretreatment in the water purification process. The advanced oxidation module 10 includes a hydroxyl radical generator, which can generate hydroxyl radicals, and the strong oxidation of hydroxyl radicals can degrade water organic pollutants, and kill bacteria, viruses and other microbial pollutants in the water.

[0028] The activated carbon module 20 is used for secondary filtration in the water purification process, including an activated carbon filter elem...

Abstract

The invention discloses a water purification method and system. The water purification system comprises an advanced oxidation module, an activated carbon module and a reverse osmosis membrane module;the advanced oxidation module comprises a hydroxyl free radical generating device, hydroxyl free radicals generated by the hydroxyl free radical generating device have a strong oxidation effect, organic pollutants in water can be effectively degraded, microorganisms such as bacteria and viruses in the water can be killed, and therefore purified water with higher quality can be obtained.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a water purification method and system. Background technique [0002] The reverse osmosis water purifier is a relatively common household water purification equipment on the market. The inside of the reverse osmosis water purifier includes an activated carbon filter element pretreatment part and a reverse osmosis membrane filter element water purification part. Activated carbon is used to adsorb particles, colloids, residual chlorine and some organic pollutants in water, and can be used as a pretreatment process in the water purification process; the pore size of the reverse osmosis membrane filter element is as small as about 0.3nm, which is used to intercept viruses, bacteria, solids, etc. Soluble substances, metal ions and some organic pollutants can be used as a deep filtration process in the water purification process. [0003] However, studies have sho...
