PROCESSING OF WASTE INCINERATION ASHES

摘要

The invention relates to a method for processing waste incineration ashes (A), in particular domestic waste incineration ashes (HMVA), in which the ashes are classified into a plurality of fractions of different grain size distributions in a processing plant (11) separated from the actual waste incineration process. The ashes (A) are classified exclusively using a wet classification process in the processing plant (11), only wet classification processes that are gentle to the grains being used, and the wet classification process is performed in such a way that all of the ashes (A) are classified into at least one fine fraction (I) loaded with harmful substances and at least one coarse fraction (II, III) that contains only a small amount of harmful substances or no harmful substances at all.

1. A method for processing incinerator bottom ash (A) in which the ash (A) is classified into a plurality of fractions (I, II, III) of different grain size distribution in a processing plant (11) separate from the actual incinerator,
the classification of the ash (A) in the processing plant (11) taking place only by a wet classification; wherein only wet classification processes gentle on the grain are used in the classification; and wherein the wet classification is carried out such that the ash (A) is classified completely into at least one contaminated fine fraction (I) and at least one low-contaminant or contaminant-free coarse fraction (II, III).
