PROBLEM TO BE SOLVED: To provide an incineration ash treatment method which efficiently removes a chlorine component from incineration ash formed in a waste incinerator to recycle the treated incineration ash as resources as a raw material, for example, for a cement. SOLUTION: Incineration main ash discharged from a waste incinerator 1 is supplied to a vibration screen 3 without being subjected to water dipping treatment not only to remove coarse foreign matter but also to remove iron refuse or the like by a magnetic sorter 2. The incineration ash from which coarse foreign matter is removed is washed with water sprincled from nozzle 7 while moved on a belt filter 6 to be immediately subjected to solid-liquid separation and a chlorine component is dissolved in water to be removed. The fine particulate solid from which a chlorine is removed to remain on the belt filter 6 receives the addition of a component control agent such as clay or silica to be mixed by a kneader 10 with the component control agent and the resulting mixture is discharged to a storage pit 11 temporarily to be stored therein.
