SOLUTION: The method for disposing waste water comprises the steps of disposing waste water having the acid component in an activated carbon column, in a weak basic anion exchange resin column and then in a double-layered column in one unit of which a strong acidic cation exchange resin layer and a strong basic anion exchange resin layer are formed separately.
