PROBLEM TO BE SOLVED: To provide an incineration ash treatment apparatus which can reduce pH of waste ash incineration ash without scaling up an apparatus and suppress the elution heavy metals, a waste incinerator, an incineration ash treatment method and a waste incineration method.SOLUTION: An incineration ash treatment apparatus comprises: a classifier 8, which receives incineration ash exhausted out of a waste incinerator 1 to classify the incineration ash into large-diameter incineration ash having a grain diameter is larger than a predetermined grain diameter and small-diameter incineration ash having a grain diameter smaller than the predetermined grain diameter; and a reactor 10, which receives the large-diameter incineration ash to mix the small-diameter incineration ash with water and receives the exhaust gas exhausted out of the waste incinerator 1 to make the exhaust gas react on contact with the small-diameter incineration ash.SELECTED DRAWING: Figure 1 |
