Double-core direct drinking water system

Abstract

The invention provides a double-core direct drinking water system which comprises a raw water tank, a raw water booster pump, a direct drinking water tank, a raw water pretreating unit, a supplied direct drinking water disinfection and filtration unit, a direct drinking water supply unit, a direct drinking water purifying and generating unit, a multi-channel valve and a control unit. According tothe invention, tap water is introduced into the raw water tank; the raw water booster pump pumps water in the raw water tank into the raw water pretreating unit; the raw water pretreating unit delivers preliminarily treated water into the direct drinking water purifying and generating unit which is one or two selected from the group consisting of a two-stage reverse osmosis membrane unit and a nanofiltration membrane unit, wherein, the number of a smaller unit is greater than or equal to 2, and the smaller units are respectively provided with solenoid valves; water enters into the supplied direct drinking water disinfection and filtration unit through the solenoid valves and then is stored in the direct drinking water tank; the direct drinking water supply unit communicates with the direct drinking water tank and the multi-channel valve; the multi-channel valve communicates with a pipeline; the control unit controls all the processes mentioned above. The direct drinking water system is capable of producing direct drinking water with different quality, more than two, thereby meeting needs of different groups of people.

Description

technical field [0001] The invention relates to the technical field of drinking water, in particular to a dual-core direct drinking water system. Background technique [0002] At present, in high-end communities and office buildings, in addition to tap water, direct drinking water is also provided for the needs of users. The general method is to set up pipelines and supply them separately, which solves the problems of domestic and direct drinking water. However, with the improvement of living standards, people's demand for direct drinking water has increased accordingly. Single-quality direct drinking water is difficult to meet people's needs. However, according to traditional methods, each type of direct drinking water supply requires separate pipelines. The cost is high, and for already built communities and buildings, it is impossible to bury new pipelines for water supply, so it is difficult to meet people's needs. Contents of the invention [0003] The purpose of the...
