Cyanide and formate destruction with ultra violet light

摘要

A method for substantially reducing cyanide and formate concentrations in gasification wastewater streams comprising first removing suspended solids from the wastewater stream, then adding sufficient hydrogen peroxide to completely oxidize contained cyanide ions and formate ions to form a feed solution, and then irradiating the resultant solution with sufficient UV light so as to substantially reduce said contained cyanide ions and formate ions.
