摘要： PROBLEM TO BE SOLVED: To provide a decolorization method of colored beverage drain having inexpensive and excellent decolorization effect.
SOLUTION: Raw water is introduced into a coagulation reactor 1 where settled sludge of a settling tank 2 of the next stage, PAC, and sodium hydroxide as pH adjusting alkali are added thereto, to keep pH to 6.5-7 for coagulation-reaction. Coagulation-reaction water is introduced into the settling tank 2 for settling separation. Part of the settled sludge is added to the reactor, with the remaining discharged as surplus sludge. Supernatant from the settling tank 2 is filtered in a filter 3, the filtrate of the filter 3 being added with sodium hypochlorite, passed through a catalytic column 5 packed with a catalyst, and taken out as treated water. Peroxide of a metal such as nickel is suitable as the catalyst.
