Evaluation of Technologies for Treating Aqueous Metal/Cyanide Bearing Hazardous Waste (F007)

摘要

As a result of recent developments in the area of hazardous waste management, the U.S. Environmental Protection Agency is evaluating the performance of various technologies for the treatment and/or destruction of certain wastes that are presently being disposed of in landfills and surface impoundments. As a part of this program the University of Cincinnati, at the U.S. EPA Test and Evaluation Facility in Cincinnati, Ohio, is testing existing treatment technologies that are applicable to metal and cyanide bearing hazardous wastes. The following unit processes have been evaluated: alkaline chlorination, precipitation, filtration, anion exchange and cation exchange. Results of the studies are presented.
