PURPOSE:To provide a recovered water desalting device which contributes to the improvement of an outlet water quality in a recovered water/desalting tower and in turn, the amelioration of water quality in a nuclear reactor by allowing the total organic carbon eluded from an ion exchange resin at a rapidly increasing rate in the early stage of water supply to flow out of the system purifying the ion exchange resin using warm water. CONSTITUTION:This recovered water desalting device consists of a recovered water desalting tower 20 equipped with an ion exchange resin 21 for purifying a recovered water, a cationic exchange resin regeneration tower 22 for separating the used ion exchange resin 21 into a cation exchange resin and an anion exchange resin, to regenerate the separated cation exchange resin, an anion exchange resin regeneration tower 23 for regenerating the separated anion exchange resin, and a warm water supply device 27 for supplying warm water to purify the regenerated cation exchange resin and anion exchange resin. |
