The safety problem of drinking water is caused by pollution caused by microorganisms, chemical substances, physical factors and the like. Tap water in most cities of China is disinfected by chlorine, and the chloride generated in the disinfection process has the 'three-cause' effects of carcinogenesis, teratogenesis and cell mutation. In addition, tap water may cause secondary pollution during transportation, and thus, people who drink tap water directly tend to be reduced along with changes in life styles of people. Under the circumstances, bottled water, and water purifier begin to get into more and more families, and wherein, the water purifier receives people's attention more and more with low cost, quality assurance and convenient operation's advantage. However, the water purifiers in the current market rely on a simple physical filtration and adsorption process, the removal of pollutants is not thorough, and the efficiency is low.
