PROBLEM TO BE SOLVED: To provide a condensed water treating method capable of efficiently removing org. acid ions from condensed water and desalting the condensed water. SOLUTION: In this condensed water treatment method, condensed water containing org. acid ions is passed through a condensed water treatment apparatus 1 having desalting towers 2a, 2b... wherein mixed bed type resin beds 5a, 5b... packed with anion and cation exchange resins 5a, 5b... are formed on the downstream side of anion exchange beds 6a, 6b... packed with an anion exchange resin, and org. acid ions are exchanged and adsorbed by the anion exchange resin beds 6a, 6b... to be removed to desalt the condensed water in the mixed bed resin beds 5a, 5b.... |
