Abstract
PURPOSE: To prevent the elution of noxious matter of heavy metals etc. contained in solidified material after treatment, by heating and fusing after regulating weight ratio of CaO and SiO2 in the ash of industrial waste products in a sepecifically fixed extent.
CONSTITUTION: SiO2 components, such as river sand, silica sand, diatomaceous earth etc. or CaO components, such as lime, quicklime etc., are added to various industrial waste products, such as sludge, municipal garbage etc. and are heated and fused after regulating weight ratio of CaO and SiO2 in the ash of waste matter in the extent of 1.0≤CaO/SiO2≤3.0 and preferably 1.5≤CaO/SiO2≤2.5.
