Zusammenfassung:	PROBLEM TO BE SOLVED: To decompose dioxin or heavy metal in fume-cleaned sewage without using a special device and to collect the heavy metals on one place in incineration of wastes. SOLUTION: In this waste incineration method, the dust is removed from a flue gas from an incinerator by a dust collector and the exhaust gas after the dust removing, is cleaned by a wet type fume cleaning method. The fume cleaning drain generated by the wet fume cleaning method is aggregated and concentrated to be the fume-cleaned sewage, and returned to the incinerator, whereby the dioxin in the sewage is heated and decomposed, and the heavy metal is returned to the dust collector with the flue gas through the incinerator, to be taken out as the collected ash.
