Tap water purification system

Abstract

The invention provides a tap water purification system. The system comprises an ozone zone sterilizer, a raw water tank, a raw water pressurization pump, an air-lift type sand filter, an iron and manganese removal filter, an activated carbon filter, a water softener, a cartridge filter, a photo-catalytic reactor, ultrafiltration equipment, nanofiltration equipment and a sterile water storage tank which are sequentially connected with one another by virtue of pipelines, wherein a countercurrent forming device and a water tank filtering net are arranged inside the raw water tank; the countercurrent forming device comprises two upper and lower funnel-shaped parts; a water flow channel is formed in the middle of the bottom of the upper funnel-shaped part; the bottom of the lower funnel-shaped part is sealed; the water tank filtering net is positioned below the countercurrent forming device, so that the raw water tank is divided into an upper chamber and a lower chamber; and a pH control device is arranged in the raw water tank. The water quality of the treated tap water can reach and can be higher than the new edition standard of domestic drinking water sanitary standard (GB5749-2006).

Description

technical field [0001] The invention relates to a tap water purification treatment system, which belongs to the technical field of water treatment. Background technique [0002] Tap water refers to the water that is purified and disinfected by tap water treatment plants and meets the corresponding standards for people's living and production use. Domestic water is mainly drawn from rivers, lakes, groundwater, and surface water through the water intake pumping station of the water plant, and the water plant is processed by the water plant in accordance with the "National Domestic Drinking Water Relevant Hygienic Standards" through processes such as sedimentation, disinfection, and filtration, and finally passes through the water distribution pumping station sent to each user. [0003] Tap water is closely related to people's lives, and the quality of tap water is closely related to people's health. my country's water quality standards are still far behind the international ...

AI Technical Summary

Problems solved by technology

However, the pollution of water resources is becoming increasingly serious, especially heavy metal pollution and organic matter pollution. According to statistics, about 50% of my country's surface water sources are polluted, and hundreds of organic compounds and heavy metal ions enter the water source; groundwater sources contain fluorine, arsenic, and iron. , manganese and other excessive phenomena

However, most of the water plants in our country still use traditional water treatment processes. If the water source is polluted by heavy metal ions and organic compounds, the above-mentioned traditional processes will be powerless.
