PROBLEM TO BE SOLVED: To enhance oxidizing treatment efficiency of decoloration, bleaching or deodorization while reducing treatment cost by supporting activated seeds of hydrogen peroxide on an ion exchange resin and subjecting an objective substance to oxidizing treatment continuously and efficiently by activated hydrogen peroxide. SOLUTION: In oxidizing treatment such as decoloration treatment of industrial waste water issued from a dye manufacturing factory or decoloration/ bleaching treatment of an org. material, hydrogen peroxide or peroxide forming hydrogen peroxide is added to org. matter and this org. matter is brought into contact with an ion exchange resin on which activated seeds of hydrogen peroxide are supported. At this time, as peroxide, a sodium carbonate hydrogen peroxide adduct, a sodium perborate hydrate and sodium perborate tetrahydrate are used and, as activated seeds of hydrogen peroxide, a halogenoide ion compd., that is, a cyanic ion compd. or a thioxyanic ion compd. is used. As the ion exchange resin, a strong or weak basic anion exchange resin is used. |
