Zusammenfassung:In the degradation of organic compounds in an effluent by oxidizing the effluent at an elevated temperature with oxygen, the improvement which comprises effecting the oxidation at a redox potential of from about 300 to 600 millivolts, as measured with a platinum electrode against a silver-silver chloride electrode, at a temperature of from about 80 DEG to 250 DEG C and under a pressure of from about 30 to 200 bars. The redox potential may be maintained by an Fe2+ and/or Fe3+ ion system and the pH is advantageously below about 7.
