  • Method for oxidative degradation of ion exchange resin
    Patent number: 10475544
    Abstract: A method of oxidative degradation is provided for waste of ion exchange resin. Therein, oxidative deactivation is processed through a fluidized bed. A column-type reactor is used to fluidize solid of the ion exchange resin. The reactor schematizes the input and output of an ion exchange resin, an oxidant, a catalyst and a fluid. The reactor controls the reaction temperature. The reactor separates solid and liquid, and uniformly distributes fluid. The present invention fluidizes the ion exchange resin in the reactor. The present invention processes oxidation within a controlled temperature range with the oxidant and catalyst added. The oxidation is maintained at high efficiency with easy control. The original structure and the characteristic of ion exchange of the ion exchange resin are destroyed.
