摘要:
A method for harmless disposal and resource utilization of resin desorption liquid generated in the ion exchange process is provided. Resin desorption liquid is channeled into an electrolytic tank, which is arranged with an inlet and an outlet; the anode and the cathode within the electrolytic tank are separately connected to a stabilized power supply; both the direct and indirect oxidation process and occurred at the anode can decompose the organic pollutants in the desorption liquid; with necessary replenishment of fresh regeneration agent, the treated desorption liquid can exert excellent performance in regenerating saturated resin; the recycled use of resin desorption liquid is therefore realized, which consequently avoids unnecessary waste of regeneration agent and reduces the final yield of the desorption liquid. This method is characterized by being convenient in operation, without addition of extra reagents, without secondary pollution, and suitable for the desorption liquid with wide pH variations.
