The invention discloses a recycling process for waste adsorbent resins. The recycling process comprises the following steps of: preparing sodium hydroxide and an organic solvent into a 4% solution, and heating up the solution to 35 DEG C to 38 DEG C; reversely adding an exchange column which is filled with to-be-treated adsorbent resins to 3BV-4BV of the prepared liquid sodium hydroxide organic solvent at the flow velocity of 1.5BV/H; stewing and soaking the solution for not less than 4 hours and exhausting the waste liquor in the exchange column; leaching the exchange column filled with the adsorbent resins by using reverse osmosis water until the pH of the exchange column is approximate to 9; and adding 1% hydrochloric acid from the bottom of the exchange column until the exhausted waste liquor is acid, and leaching the exchange column by the reverse osmosis water until the exchange column is nearly neutral. According to the recycling process disclosed by the invention, the single-time de-colourization rate of the exchange column is improved; and moreover, the single-time using period of the exchange column can be enabled to be more than 90% of the novel resin; the use period is prolonged; and the production cost is saved.
