Water is a kind of life resource, which is necessary for the normal metabolism of human body. In order to ensure the safety of basic water use, China formulated and promulgated the sanitary standard for drinking water (GB5749-2006) as early as 2007. In reality, when people take the initiative to use water, the water quality is still difficult to really achieve health and quality. In order to protect health and ensure the quality of life, filtering out various factors (physical, chemical and biological) that affect health in drinking water has become a common demand of the people.
