Healthy direct drinking water preparation system

Abstract

The invention discloses a healthy direct drinking water preparation system which comprises a pretreatment unit (1), a core treatment unit (2), a disinfection treatment unit (3) and a water quality adjusting unit (4). The pretreatment unit (1) is used for initially treating original water and initially filtering impurities in the original water, the core treatment unit (2) is communicated with the pretreatment unit (1) and receives water initially treated by the pretreatment unit (1), the core treatment unit (2) comprises an ultra-filtration membrane treatment device and a nano-filtration membrane treatment device which are parallelly connected and used for removing hardness, monovalent ions and divalent ions in water, the disinfection treatment unit (3) is communicated with the core treatment unit (2) and used for disinfecting for the water and receives water treated by the core treatment unit (2) in a core manner, the water quality adjusting unit (4) is communicated with the disinfection treatment unit (3) and receives the water disinfected by the disinfection treatment unit (3), and the water quality adjusting unit (4) comprises a mineralization filter (24) for mineralizing water and conveying direct drinking water to users. The system solves the problem that trace elements are overly removed, and healthier direct drinking water is prepared.

Description

technical field [0001] The invention relates to a direct drinking water system, in particular to a healthy direct drinking water preparation system which avoids excessive removal of trace elements. Background technique [0002] With the further development of urban civilization, people have higher and higher requirements for the quality of urban water supply. People pay more attention to their own safety and health, and the way of drinking water has also changed. Direct drinking water gradually emerged at the end of the last century. [0003] The traditional direct drinking water preparation technology often adopts reverse osmosis membrane treatment technology. The reverse osmosis membrane can effectively remove divalent ions, monovalent ions, organic pollutants and inorganic pollutants. The disadvantage of direct drinking water purification is that all harmful substances in the water are removed. At the same time of removal, almost all the trace elements that are beneficial...
