WATER TREATMENT METHOD AND SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a water treatment method and system in which treated water suitable for recycling can be obtained by using ion exchange.

SOLUTION: This water treatment system comprises: a electrolyzer 1 oxidizing and decomposing removing objects contained in waste water 20 by electrolysis; an ion exchange apparatus 2 packed with negative ion exchange resin and separating the removing objects by ion-exchanging electrolyzed liquid 22 flowing from the electrolyzer 1; and a return line for returning regenerated waste water 25 by the negative ion exchange resin to the upstream side of the electrolyzer 1.
