Abstract
A process and a set of equipment for reactivating spent activated carbon onto which pollutants were adsorbed. The present process comprises subjecting the activated carbon to be reactivated in a mixed solution consisting of ethanol, sodium hydroxide solution and water to effectuate the desorption of the pollutants adsorbed on the activated carbon. The equipment includes (A) a mixing tank for mixing given amounts of water, ethanol and sodium hydroxide solution which are supplied from the respective receptacles thereof; (B) a reactivation reactor for receiving the mixed solution from the mixing tank and subjecting the spent activated carbon filled therein to the mixed solution to effect the desorption of the pollutants adsorbed on the spent activated carbon, wherein the reactivation reactor includes a unit for regulating temperature of the mixed solution; and (C) a storage tank for receiving the reactivated carbon.
