Description

A deep ultraviolet sterilizing device

technical field

The invention relates to the field of water treatment, in particular to a deep ultraviolet sterilizing device.

Background technique

Water is the source of life. With the serious pollution of the environment, the quality of drinking water is getting worse and worse. Most of the water used in cities comes from water purification plants. However, chemical substances such as bleach and disinfectant are used in the process of water purification, and a certain amount of chlorine or ammonia will remain after use. During the transportation of tap water, it will enter our kitchen and our life through the water storage booster system and a series of water pipes. The iron water pipes will inevitably produce some rust after long-term use. Because the water storage system is difficult to clean and purify, it is generally cleaned once a quarter, during which E. coli and algae bacteria will breed. In order to ensure the safety of drinking water, many families have purchased water purifiers, some with simple filtration, such as faucet water purifiers that only rely on PP cotton, activated carbon, compressed carbon, etc.; Tap water is thoroughly filtered, such as a pure water machine; there is also an ultrafiltration water purifier that filters tap water through an ultrafiltration membrane to make it meet kitchen and drinking water standards. The water purification of the water purifier is very effective, but usually we ignore the problem that the water purifier itself will breed bacteria after long-term use. For example, in order to improve the taste and absorb organic matter, the activated carbon filter element installed in the water purifier is generally installed after water purification. The self-pollution problem of the activated carbon medium is like a super sponge, which absorbs a large amount of toxic and harmful pollutants. If it stays for a long time, a large number of bacteria will multiply in its micropores, especially if some drinking water equipment is installed in a cold and humid place or in direct sunlight, the bacteria will multiply faster. The outlet of the faucet to the activated carbon filter element has become a breeding ground for bacteria, which will not only fail to purify the water quality, but will pollute the water quality instead.
