Abstract

The invention relates to a direct drinking water purifying method and a direct drinking water purifying device. The direct drinking water purifying method comprises three-stage treatment steps, namely active carbon adsorption, ultra-filtration film filtration and ultraviolet sterilization in turn. The direct drinking water purifying device comprises a shell, and a water inlet and a water outlet which are connected on the shell; and the device also comprises a first-stage carbon adsorption treatment device, a second-stage ultra-filtration film treatment device and a third-stage ultraviolet treatment device. The method and the device can effectively solve the problems of poor trace pollutant removing effect, secondary pipeline pollution and the like in the conventional drinking water treatment process through a technique with low energy consumption and low cost.

Description

Technical field: [0001] The invention relates to a water purification method and device, in particular to a purification method and device for direct drinking water. Background technique: [0002] With the rapid development of social economy, the discharge of living and production pollutants is increasing, the water quality of water sources is gradually deteriorating, and there are more and more pollutants in water, especially organic pollutants. Pollutants in water are usually divided into three categories, namely biological, physical and chemical pollutants. Biological contaminants include bacteria, viruses and parasites. Physical pollutants include suspended solids, thermal pollution and radioactive pollution. Chemical pollutants include organic and inorganic compounds. [0003] Traditional water treatment technologies (such as coagulation, sedimentation, filtration, and disinfection) have limited ability to remove dissolved organic matter and trace pollutants in water...
