Safe drinking water purification method and system

Abstract

The invention relates to a purification method and a purification system for safe drinking water. In the method, tap water is treated by ultrafiltration or microfiltration and divided into two strands, which are respectively subjected to nanofiltration and active carbon adsorption treatment, and then combined together for disinfection. While removing toxic and harmful pollutants in the tap water of the pipe network, it also retains trace elements beneficial to the human body, and has the advantages of low treatment cost and high water recovery rate. The system includes: the ultrafiltration or microfiltration unit communicates with the nanofiltration unit through a water pipe through a tee, and one port is sequentially connected with an ozone oxidation treatment unit and an activated carbon unit, and the ozone oxidation treatment unit is a traversable unit. The nanofiltration filter unit and the activated carbon unit are connected through a water delivery pipe, an outlet is set on the water delivery pipe, and then connected with the water storage tank through the water delivery pipe; the water storage tank is connected with the online disinfection unit and the household pipeline to form an independent circulation system. Realize the automatic control of the treatment process, and make the treated water meet the drinking water standard.

Description

technical field [0001] The invention relates to a water purification method, in particular to a purification method and a purification system for deep processing tap water for direct drinking. Background technique [0002] In recent years, about 90% of my country's urban waters have been polluted to varying degrees, resulting in the deterioration of most drinking water sources, and the types and contents of organic pollutants in water sources are also increasing. At the same time, since most water plants adopt chlorine disinfection methods, secondary pollutants such as trihalomethanes and haloacetic acids are often produced in the water, which have direct or potential impacts and hazards on human health. In addition, due to the complexity of the urban water supply network, re-pollution often occurs during the transportation of drinking water. Studies have proved that water pipe corrosion and microbial reproduction will occur in the transmission and distribution network. Th...
