いている。2. Description of the Related Art Water purifiers are widely used for household and commercial purposes, and most of them are treated with activated carbon. The activated carbon used in these water purifiers is incorporated as a cartridge, and when the ability to remove chlorine and musty odor is lost, the activated carbon cartridge is replaced. In particular, the water purifier for home use has a drawback that the activated carbon cartridge is small, and the activated carbon cartridge needs to be replaced every six months, which is troublesome. Further, in recent years, since various bacteria propagate to remove chlorine with activated carbon, expensive activated carbon cartridges, such as those incorporating a hollow fiber membrane filter and those using antibacterial activated carbon, are increasing in number, resulting in high running costs.

とがあり実用化されていなかった。There are some examples of porous adsorbent resins used for water treatment and decolorization of foods, but in water purifiers, especially household water purifiers, when the porous adsorbent resin dries, it shrinks. Since the pores are crushed and the adsorptivity is lost, and anaerobic bacteria may grow in a wet state, they have not been put into practical use.

再生方法が採られている。Here, the porous adsorption resin will be described. When a solute is adsorbed by a polymer such as an ion exchange resin, the solute diffuses and permeates not only the surface but also the inside and is adsorbed. For this diffusion and permeation, the pores of the polymer play the role of solute passages, and the one having a large volume of this pore is called a porous adsorption resin. Also, these pores are formed between polymer chains or between polymer chains and crosslinks, which typically occurs in ion exchange resins, but they are adsorbed on the concentration of the electrolytic chamber, the nature of the solvent, and the ion exchange groups. It is affected by various factors such as the nature of the ions being formed and temperature. Therefore, various regeneration methods are adopted depending on the characteristics of the porous adsorption resin.

As shown in FIG. 3, the regeneration of the porous resin utilizes the fact that the adsorption characteristics of the porous adsorption resin have a large adsorption amount from acidic to weak alkali and sharply decrease when it becomes strong alkali, which is highly dependent on pH.
