Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a decoloring cleaning method of contaminated waste water, by which decoloring of contaminated waste water including colored organic substances and oxidative decomposition reaction of contaminants can be very efficiently carried out.SOLUTION: Air-containing gas is blown in the contaminated waste water including the colored organic substances and the waste water in a gas liquid mixing state is made to pass through a reaction tower filled with a carbonaceous material on which a microorganism film is formed. Then electrolytic functional water which is obtained by electrolysis of electrolyte aqueous solution including chloride ions by using an iridium oxide-containing electrode as an anode, is added to cause reaction and then the water is made to pass through a catalytic reaction tower filled with an organic porous material including iron oxide at the subsequent stage.
