METHOD FOR DESALTING CONDENSED WATER OR WASTE WATER IN NUCLEAR POWER PLANT

摘要

To provide a desalting method capable of increasing the life of an ion exchange resin in an apparatus for desalting condensed water or waste water by decomposing an oxidation promoting material existing in the condensed water in a nuclear power plant to reduce the exchange frequency of the ion exchange resin.SOLUTION: The method for desalting the condensed water or waste water of a nuclear power plant comprises: forming a mixed bed having a uniform distribution between a strong acidic cation exchange resin having 1-5 cm/s of an end speed uniquely determined by the particle size and specific gravity of an ion exchange resin and a strong base anion exchange resin in the condensed water or waste water treatment of the nuclear power plant; and passing the condensed water or waste water through an apparatus for desalting the condensed water or the waste water, charged with the ion exchange resin layer obtained by overlaying a metal support resin at a volume ratio of 2-50% on the entire surface of the mixed bed without separating the strong acidic cation exchange resin and strong base anion exchange resin of the mixed bed once formed.SELECTED DRAWING: None
