Abstract
PURPOSE: To prevent the efflux of harmful substances as well as to make operability easier by a low-cost and energy-saved solidification method in which inorganic sludge is dehydrated, molted with a Ca component, and then subjected to a steam autoclave treatment.
CONSTITUTION: The inclusion of a Ca component in inorganic sludge to be treated is essential. An inorganic sludge is mixed with a Ca component, e.g., slaked lime, quick lime, calcium carbonate, calcium sulfate, etc., either solely or in combination and also with a solidification accelerator, e.g., a siliceous substance, a clay, an aluminum compound, a waste containing these, etc., either solely or in combination, and then molded. Then, the molded fine powder is subjected to an autoclave treatment with pressurized water vapor for further solidification.
