It should be noted that the description of "… … μm" in this application should be understood in a broad sense, and refers to the use of resins or activated carbon with different particle sizes, which are made by mixing particles with different particle sizes. Therefore, the resin or the activated carbon is mixed more uniformly, and the subsequent pollutant adsorption is facilitated.

According to the embodiment of the invention, heavy metal pollutants (such as copper, cadmium and the like) generally exist in the form of cations in water, so that the cations in the cation exchange resin can be used for exchanging with the heavy metal cations in order to remove the heavy metal pollutants, so that the heavy metal cations are adsorbed on the resin, and the purpose of purifying the water is achieved.

Therefore, the cation exchange resin has better effect of removing heavy metal pollutants or industrial pollutants, better water purification effect and better mouthfeel of drinkable water. In some embodiments of the invention, the cation exchange resin comprises a potassium ion exchange resin and a hydrogen ion exchange resin. Therefore, when the cation exchange resin and the hydrogen ion exchange resin exist simultaneously, the effects of removing heavy metal pollutants, removing industrial pollutants, removing residual chlorine and calcium and magnesium ions are better, the potassium ions in the potassium ion exchange resin are exchanged into purified water to improve the alkalinity of the purified water, the hydrogen ions in the hydrogen ion exchange resin are exchanged into the acidity which can improve the water in the purified water, and the two exist simultaneously to adjust the pH value of the purified water, so that the pH value of the purified water is closer to neutral, and the taste of the purified water is better.
