Description

A dynamic water UV water purifier

technical field

The utility model relates to the technical field of water purification, in particular to a dynamic water ultraviolet water purifier.

Background technique

At present, the quality of drinking water involves human health is a global concern. According to the World Health Organization (WHO) survey, 80% of the diseases and 50% of child deaths in the world are related to poor drinking water quality, and more than 50 diseases are caused by drinking water quality. Tap water is an important source of water for people for a long time. After the surface water or groundwater is extracted, it enters the municipal water network and flows into thousands of households after flocculation reaction treatment, sedimentation treatment, filtration treatment and disinfection treatment. Due to environmental pollution, there are obvious differences in the water quality of water sources in different places. Generally speaking, it is difficult to achieve a 100% pass rate. There are cases where the water quality exceeds the standard. In addition to the water source factor, secondary pollution is unavoidable due to the long pipe network distance between the water plant and the user terminal. The water pipe network in many places is seriously aging. Long-term use of water pipes will cause corrosion, resulting in rust, moss, and bacterial growth. If the aging is serious, leakage will occur, allowing external pollutants to enter the tap water. The tap water that goes into a home's mains has changed a lot from the quality that just came out of the waterworks. The water quality of this secondary water supply will make the filter heads of the faucets used at home easily accumulate scale, which will further pollute the tap water. CCTV reported the survey results of my country's National Development and Reform Commission. The unqualified rate of tap water that just came out of the waterworks was 17%, and the unqualified rate of the taps reached more than 20%. The data is very scary.

In the treatment of drinking water, people traditionally use high-temperature boiling for sterilization. On the one hand, high-temperature disinfection can only eliminate harmful bacteria colonies that are not resistant to high temperature, such as Escherichia coli, but cannot achieve the effect of broad-spectrum sterilization to prevent microbial contamination of water quality. Ensure the safety of drinking water. On the other hand, many people will buy water purifiers at home to filter microorganisms and impurities and purify tap water. The core component of the current water purifier is a filter element containing a variety of filter materials. The multi-stage filter element does have a better water purification function. It has a good removal effect on particulate impurities, harmful elements and microorganisms within a certain period of time. There are mainly three types of water purifiers with microbial filtration function on the market: ultrafiltration, nanofiltration and reverse osmosis. The microfiltration membrane cannot deeply filter microorganisms, and the filtration effect will be significantly weakened with the prolongation of use time. In addition, other areas of the water purifier except the filter element components will also generate cross-contamination caused by microbial growth after a long period of use. The filtration effect of reverse osmosis is better than that of ultrafiltration and nanofiltration, but the filtration rate of reverse osmosis water purifier is slow, the flow rate of purified water is small (about 1LPM), and a large amount of waste water is generated at the same time. It is necessary to configure the waste water storage tank and the booster pump water purifier with a large volume.
