Water purification system

Abstract

The invention discloses a water purification system. The water purification system comprises an ozone oxidation system, an activated carbon filtration device, a first filter, a second filter and a purified water tank, wherein a water distribution plate is also arranged at the inner upper end of an ozone oxidation tower and is positioned below a raw water inlet; the activated carbon filtration device is communicated with an oxidation water outlet through a pressurizing pump, a water outlet of the activated carbon filtration device is sequentially communicated with a water inlet of the first filter, a water outlet of the first filter, a water inlet of the second filter, a water outlet of the second filter and a water inlet of the purified water tank, and a filter core of the activated carbon filtration device adopts a hollow structure. The water purification system disclosed by the invention has the beneficial effects that the service life of an ozone generation unit is prolonged; one filter core is used, so that three-stage pretreatment of water is realized, the volume of the filter core is reduced, and the abandonment size of the solid filter core is also reduced; the water distribution plate is arranged in the ozone oxidation tower, so that the utilization rate of ozone is increased; running water can be deeply purified, and outlet water is more clean.

Description

technical field [0001] The invention relates to the field of drinking water treatment, in particular to a water purification system. Background technique [0002] The quality of the existing tap water has not met the requirements for direct drinking, and it needs to be treated twice before drinking. In terms of treatment process, there are multiple purification and filtration; in terms of treatment equipment, there are household water purifiers, central processing water purification stations, etc. In terms of supply methods, there are terminal processors, bottled water and piped drinking water. Central water purification stations are usually used to provide water sources for direct drinking water in pipelines, and the core technology of water treatment is membrane filtration. Due to the different membranes, the derived water treatment processes are also different. The currently used membranes mainly include reverse osmosis membrane, nanofiltration membrane and ultrafiltra...

AI Technical Summary

Problems solved by technology

Because the ozone will be rapidly decomposed during the pressurization process, and the loss is as high as more than 60%. In addition, the bubbles generated by the current aerator are large, and most of the ozone will be decomposed and volatilized when entering the water body, so it needs to be improved.
