Description
Technical Field
The utility model relates to the technical field of direct drinking water treatment, in particular to a direct drinking water system.
Background
The drinking water is a direct water source, and everyone can not drink water in daily life. The direct drinking water is used as drinking water which is frequently drunk by people, various technical means are adopted to kill viruses and bacteria in the water, and different colors, peculiar smell, residual chlorine, heavy metals and the like in the water are filtered out, so that the direct drinking water completely meets the standard of directly drinking healthy water, and therefore whether the direct drinking water meets the standard or not is judged, and the direct drinking water is related to a water source and also has a very direct relation with treatment facilities.
In our daily life, especially in town life, tap water is usually used as a drinking water source for direct drinking water, and as the requirements of people on living standards are gradually increased, the importance of the quality and safety of drinking water is gradually increased. In water works, most of the water works adopt the traditional water treatment process, and many tap water pipe networks adopt gray cast iron pipes installed in seventies, and the pipelines are corroded by chloride ions in tap water for long service time and years, so that the phenomena of running, overflowing, dripping and leaking are more and more, and secondary pollution of water quality is caused. Moreover, the pipelines have longer service life and serious rust and corrosion, and even if the effluent of a water works reaches the standard, rust in the pipelines, heavy metals and bacteria which are corroded and oozed out of the pipelines can further cause secondary pollution of tap water after the pipelines are transmitted. So that the tap water can be used as direct drinking water after being treated.

For example, although the conventional RO reverse osmosis membrane can remove harmful substances, minerals in the water body are removed at the same time, if the water quality is drunk frequently, the loss of the minerals is caused, and the RO reverse osmosis membrane is very unfavorable for human health, and a large amount of strong brine is produced by the RO reverse osmosis membrane, and the strong brine cannot be drunk and can only be discharged, so that the waste of water resources is caused; in addition, as the magnetization method, the magnetic field is utilized to oxidize and reduce the inorganic chemical substances to achieve the removal effect, but the organic chemical toxic substances cannot be removed, and the produced small-molecule magnetized water containing the harmful toxins such as carcinogenic and mutagenic substances. In the long-term use process of users, although the direct drinking water equipment such as a water dispenser and a direct drinking machine is sterile, the parts of the whole machine, such as a box body, a pipeline and the like, which are contacted with water can cause bacteria to grow or bacteria to attach, so that secondary pollution of the direct drinking water is caused.
