Abstract

The present invention provides a method for treating an incineration fly ash, which comprises washing and desalinating an incineration fly ash discharged from an incinerator (1) with water while moving it on a belt filter (2), immediately followed by solid-liquid separation, supplying the resultant solids remaining on the filter (2) to a kneader (6) as a fly ash cake having a water content of 45 to 60 %, kneading it until it has a concrete slump value of 20 cm, and then sending the product by pressing by a piston pump (9) to a kiln not shown in the figure through a piping (10).
