Drinking water terminal sterilization water purifier

Abstract

The present invention relates to a drinking water terminal sterilization water purifier, which comprises a pipe, a water inlet and a water outlet, wherein the water inlet and the water outlet are arranged on both ends of the pipe, a sterilization layer, a water purification layer and a heavy metal ion removing layer are sequentially stacked and are arranged inside the pipe along a direction from the water inlet to the water outlet, the sterilization layer comprises a high poly iodine resin, the water purification layer comprises active carbon particles and active carbon fibers, and the heavy metal ion removing layer comprises heavy metal nanosphere particles and a cation exchange resin. According to the present invention, all kinds of pathogenic bacteria and viruses damage harmful for human health in water can be instantly killed within 0.5 s through the high poly iodine resin in the sterilization layer, bacteria cannot grow on the high poly iodine resin so as not to generate secondary pollution, and the structure of the water purifier of the present invention is simple compared with the traditional water purifier in the case of the same sterilization effect; with the water purification layer, free iodine in the water can be neutralized and adsorbed, the residual chlorine and the organic pollutants in the water can be removed, and the taste of the water can be improved; with the heavy metal ion removing layer, the heavy metal ions dissolved in the water can be effectively removed, the hardness of the water can be reduced; and the drinking water terminal sterilization water purifier has characteristics of clogging resistance and long service life, and can be matched with other types of the filtration methods.

[0002] For life, water is indispensable, and humans are no exception. In extreme environments, the human body may become metabolically disordered beyond rescue if it lacks water for 24 hours; even under relatively comfortable conditions of temperature, humidity, and air pressure, a It is difficult for an adult to last for more than 5 days without water intake. The common process of nanofiltration or reverse osmosis water purifiers in the past is non-woven fabric, coarse filter granular activated carbon (GAC), fine filter granular activated carbon, ultrafiltration membrane, nanofiltration Membrane or reverse osmosis membrane and post granular activated carbon, a major hidden danger of this kind of water purifier is that if the water purifier has not been used for a period of time, or just for one night, the outlet and rear of the water purifier A large number of bacteria will grow inside the granular activated carbon filter, making the total number of colonies in the effluent not meet the requirements of GB5749-2006. Due to the porous characteristics of the rear granular activated carbon, it is very conducive to the growth of bacteria. After the water flows through the water purifier, the activated carbon While sterilizing the water, it will also bring out the bacteria carried by the activated carbon itself, causing secondary pollution. This is a common problem in all water purifiers sterilized by activated carbon.

[0003] In order to overcome the problem of secondary pollution caused by activated carbon sterilization, water purification technologies such as ultraviolet sterilization and ultrafiltration sterilization have appeared on the market. Although this sterilization effect is better than activated carbon, no matter what kind of water purifier, the final terminal There will still be the problem of excessive bacteria in the effluent, and it will inevitably cause the structure and process of the water purifier to become more complicated, the manufacturing cost will rise sharply, the power consumption will increase, and the service life of the water purifier will be shortened
