Abstract

PURPOSE: To make sludge harmless easily and at lower cost by the procedure in which a n-paraffin organic solvent is added with stirring to sludge containig polychlorobiphenyl and then a solidifier is added to the sludge for solidfication.
CONSTITUTION: A 12 to 16 carbon n-paraffinic solvent is added with stirring to sludge containing polychlorobiphenyl (PCB) to extract PCB present in sludge into the solvent and then a cement solidifier to added to the slidge to obtain solidified sludge from which no elution of PCB takes place.
