TREATMENT OF WASTE ACTIVATED CARBON AND TREATMENT OF ACTIVATED COKE

摘要

PROBLEM TO BE SOLVED: To provide a method for further using waste activated carbon as an adsorbing material and a method for treating waste activated carbon without using a special incinerator. SOLUTION: Waste activated carbon is blown in exhaust gas of a process of every kind and a dry distillate having adsorbed a harmful substance in exhaust gas is recovered by a dust collector to purify the exhaust gas. At this time, waste activated carbon is preliminarily subjected to regeneration treatment or dry distillation treatment to be enhanced in the adsorbing efficiency of a harmful substance. Further, if recovered waste activated carbon is utilized as a raw material for a sintering machine in an iron manufacturing process, it can effectively be put to practical use as a heat source and an ash component can be converted to slag (detoxified) finally in a blast furnace.
