Title:
WATER TREATMENT METHOD AND APPARATUS
Document Type and Number:
Japanese Patent JP2016059853
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a water treatment method and apparatus that perform water treatment using an ion exchange resin.SOLUTION: A water treatment apparatus comprises: an ion exchange treatment tank 12 where raw water is brought into contact with an anion exchange resin to remove soluble organic components contained in the raw water; regeneration means 13 for regenerating the anion exchange resin, having adsorbed the soluble organic components in the ion exchange treatment tank, using a regenerant consisting of a sodium chloride aqueous solution; and an oxidation treatment device 14 for subjecting regeneration waste liquid, generated by the regeneration of the anion exchange resin in the regeneration means, to oxidation treatment by oxidation means including generation of hydroxy radicals. The oxidation treatment device includes one or more of ozone oxidation, hydrogen peroxide oxidation, and submerged plasma oxidation. The regeneration waste liquid subjected to the oxidation treatment can be reused as the regenerant.SELECTED DRAWING: Figure 1
