The resin method has certain advantages in removing low-concentration zinc-containing wastewater from solution. When zinc-containing wastewater passes through the ion exchange resin, the ions on the exchanger are exchanged with the zinc ions in the water to achieve the purpose of removing the zinc ions in the water. This process is reversible and the ion exchange resin can be regenerated. The chelating resin provided by Jiangsu Kingshan New Material Co., Ltd. can provide suitable ion exchange resin for zinc removal according to different water quality conditions. It has high exchange capacity, convenient regeneration and long service life, and has been widely used at home and abroad.
