The invention provides an ion exchange resin regeneration method. The ion exchange resin regeneration method is characterized by comprising the following steps: (1) carrying out backwashing, namely introducing dilute regenerating liquid from the bottom of an ion exchange resin column, carrying out backwashing on the inside ion exchange resin, soaking for 25-35min, then converting the dilute regenerating liquid into concentrated regenerating liquid in a column body, and discharging the obtained concentrated regenerating liquid to a concentrated liquid collecting groove through compressed air, wherein the liquid inlet flow rate of the dilute regenerating liquid is 2-4BV / h, and the using amount of the dilute regenerating liquid is one-time bed body; (2) washing, namely, introducing 10% dilute sulphuric acid from the top of the ion exchange resin column, converting the dilute sulphuric acid into dilute regenerating liquid in the column body, discharging the dilute regenerating liquid to a dilute liquid collecting groove, and emptying residual liquid to complete the regeneration of the ion exchange resin, wherein the flow rate of the inlet liquid is 1-2BV / h and the using amount of 10% dilute sulphuric acid is one-time bed body. According to the regeneration method, the regenerating liquid is divided into the concentrated liquid and the dilute liquid, so that the using amount of the regenerating liquid can be effectively saved, and the regenerating cost can be effectively lowered.
