Title:
A processing unit of treated water, a manufacture device of pure water, and a disposal method of treated water
Document Type and Number:
Japanese Patent JP6228471
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a device for treating water to be treated that can easily prolong the durable period of a boron-selective ion exchange resin even when the boron-selective ion exchange resin is used in a treatment device of water to be treated that treats water to be treated containing boron.SOLUTION: A first ion exchange resin column 23 comprises an outer shell part 231 having a space K therein for being filled with an ion exchange resin I, an introduction part 232 for introducing water to be treated into the outer shell part 231, and a discharge part 233 for discharging the water to be treated from the outer shell part 231. The ion exchange resin I consists of a strongly basic anion exchange resin A filled into an introduction part 232 side, and a boron-selective ion exchange resin B filled into a discharged part 233 side.
