Description

A direct drinking water system

technical field

The invention relates to the technical field of direct drinking water treatment, in particular to a direct drinking water system.

Background technique

Drinking water is a source of directly imported water, and everyone cannot do without drinking water in daily life. As the drinking water we often drink, direct drinking water uses various technical means to kill viruses and bacteria in the water, and filters out the color, odor, residual chlorine, heavy metals, etc. in the water, so as to fully meet the standards of direct drinking healthy water Therefore, whether the direct drinking water meets the standard is not only related to the water source, but also has a direct relationship with the treatment facilities.

In our daily life, especially in urban life, tap water is usually used as a drinking water source for direct drinking water. With the gradual improvement of people's living standards, the water quality and safety of drinking water are also gradually increasing. . In the waterworks, most of them adopt the traditional water treatment process, and many of the water pipe networks are made of gray cast iron pipes installed in the 1970s and 1980s. The corrosion of ions leads to more and more phenomena of running, running, dripping, and leaking, resulting in secondary pollution of water quality. Moreover, these pipelines have a long service life and are seriously rusted and corroded. Even if the effluent water from the waterworks reaches the standard, after pipeline transmission, the rust in the pipeline, heavy metals and bacteria leaked from the corrosion of the pipeline will further cause secondary pollution of the tap water. Therefore, tap water must be treated before it can be used as direct drinking water.

There are many types of direct drinking water equipment on the market. Most of the core technologies mainly include composite filter element, nanofiltration, ultrafiltration, RO reverse osmosis, activated carbon, magnetization method, etc. The combination of one or more technologies focuses on water quality filtration. , water temperature, chromaticity, etc., there are certain problems. For example, the commonly used RO reverse osmosis membrane can remove harmful substances, but the minerals in the water are also removed at the same time. If you drink this kind of water frequently, it will inevitably cause the lack of minerals, which is very harmful to human health. The RO reverse osmosis membrane will produce a large amount of concentrated brine, which is not drinkable and can only be discharged, which will cause a waste of water resources; in addition, the magnetization method uses a magnetic field to oxidize and reduce inorganic chemicals to achieve the removal effect. However, organic chemical poisonous substances cannot be removed, and the output is small molecule magnetized water containing carcinogenic, mutagenic and other harmful poisons. Secondly, during the long-term use of the user, although the direct drinking water equipment such as water dispenser and direct drinking machine is sterile after its treatment, the tank, pipeline and other parts of the whole machine that are in contact with water will be damaged. Cause bacterial growth or bacterial adhesion, thus causing secondary pollution of direct drinking water.

Therefore, direct drinking water equipment must first consider human health, and secondly consider the conservation of water resources and the problem of secondary pollution.
