description PROBLEM TO BE SOLVED: To provide a mixed bed type ion exchange resin bed giving highly purified treated water. SOLUTION: The mixed bed type ion exchange resin bed is formed by mixing an anion exchange resin having repeating units of formula (1) (A is a 3-8C alkylene or a 4-8C alkyleneoxymethyl, B is a primary to tertiary amino or a quaternary ammonium, and when B is a secondary or a tertiary amino or a quaternary ammonium, an organic group bonding to N is a 1-6C alkyl or hydroxyalkyl) with a cation exchange resin having repeating units of formula (2).
