Problems solved by technology

The water treated by reverse osmosis belongs to the category of pure water. Since there are no indispensable micronutrient elements in the water, such as calcium, magnesium, iodine, etc., medical experts do not recommend that people drink pure water and distilled water for a long time, and my country's current "separation "Quality water supply" method has its own limitations in terms of equipment investment, operating cost, cost per ton of water, water quality, usage, etc.

Abstract

A nano material based high-quality water cleaning system for directly supplying drinking water is composed of ultrafilter unit, and functional filter unit whose filtering material is the mixture of activated carbon, bactericiding nano material and / or negative-ion particles. Its advantage is high cleaning effect.

Description

technical field [0001] The invention relates to the field of tap water purification, in particular to a tap water supply purification system capable of obtaining direct drinking water. technical background [0002] The quality of tap water is directly related to people's health. However, there are bacteria, viruses, pyrogens and "three-caused substances (carcinogenic, teratogenic, mutagenic)" in the tap water supply system, forming drinking water quality to the human body. Threats are microbiological (typically acute) and chemical (typically chronic). [0003] Microbial risks are due to pathogenic bacteria in drinking water. The current concept of water supply treatment, that is, the method of sedimentation, filtration, and disinfection can solve the problem of pathogenic bacteria. Even for long-distance water supply pipe networks in larger cities, as long as a certain residual chlorine at the end of the pipe network is maintained, the safety of drinking water can be guara...
