METHOD FOR DECONTAMINATION TREATMENT AND UTILIZATION AS RESOURCE OF ION EXCHANGE RESIN DESORPTION SOLUTION

Document Type and Number:

WIPO Patent Application WO/2015/165234

Kind Code:

A1

Abstract:

The present invention relates to the field of resin desorption solution regeneration. Disclosed is a method for decontamination treatment and utilization as a resource of an ion exchange resin desorption solution. The method is such that: a resin desorption solution is introduced into an electrolyzer provided at either side with a water inlet and a water outlet, where the anode and the cathode respectively are connected to a stable power source, organic substances in the solution are degraded and desorbed by means of direct oxidation and indirect oxidation effects of the anode, and, a regenerating agent is replenished to allow the desorption solution to be provided again with great resin regeneration performance, thus implementing reuse of the desorption solution, preventing wastage of the regenerating agent in the desorption solution, and greatly reducing the amount of the desorption solution generated. The method is advantageous in that it is easy to operate, requires no additional chemicals, does not produce secondary pollution, and has a broad applicable pH range. The present invention implements the regeneration and reuse of a resin desorption solution and satisfies requirements for decontamination, reduction, and reutilization of the resin desorption solution.
