| Abstract;This paper explains the following items on the titled method: 1) Objectives; to reduce environmental pollution risk to the level before reclamation and thus to create safe landfill, 2) two process components; leaching or slurry transportation for positive removal of soluble heavy metals from incineration ash (I) and dissolving into seawater and separation for classification by particle diameter to reduce environmental risk, 3) results of the first process; mechanical stirring as strong as that accompanied with slurry transportation nearly completed separation of adhered particles, components of incineration ash, in about five minutes and leaching of Cr(VI) contained in the ash could be promoted by increasing liquid/solid ratio during slurry transportation, 4) measurement result of leached heavy metal concentration of classified I after stirring; I remained on a 2 mm sieve provided leaching of heavy metals below quantitative limit value and 5) conclusion; classification by 2 mm particle diameter is desirable to develop landfill with low environmental pollution risk. |
