ABSTRACT:
A method for treating an aqueous stream containing a water-soluble, inorganic sulfide compound wherein the stream is contacted with oxygen in a thermal, non-catalytic conversion zone to convert the inorganic sulfide compound to sulfate and thiosulfate. The aqueous effluent from the thermal, non-catalytic conversion zone is then contacted with oxygen and an oxidizing catalyst on a carbon support at catalytic oxidation conditions selected to provide a high conversion of the thiosulfate to sulfate which produces a substantially sulfide-free aqueous stream.
