Abstract
1375259 Waste water treatment STAMICARBON BV 22 Dec 1972 [22 Dec 1971] 59308/72 Heading C1C Waste water containing carbonaceous contaminants is treated to convert said contaminants to gaseous reaction products, said treatment comprising oxidizing the contaminants by heating the waste water with nitric acid and/or a nitrate at a temperature between 150‹ C. and the critical temperature of water. The nitric acid and/or nitrate is preferably present in an amount less than 50% excess based on the amount of carbonaceous contaminants. Ammonium nitrate is the preferred nitrate oxidation agent. The treatment is preferably directed to the waste water derived from the preparation of an unsaturated nitrile, ammonium salt preparation wherein the salt is contaminated with carbonaceous substances, activated sludges, paper-mill effluents and a waste water contaminated with caprolactam.
