ABSTRACT:
A process for wet oxidation of a waste stream containing organic carbon and organic or inorganic nitrogen-containing pollutants which comprises initially removing organic or inorganic nitrogen-containing pollutants using a nitrate salt of an aliphatic or aromatic amine as the denitrifying agent at a temperature from 180 to 300° C. and a pressure sufficient to maintain liquid phase conditions; and, then, effecting further removal of the organic carbon containing pollutant by treatment with activated carbon, chemical oxidation, or biotreatment.
