    Abstract: A process of aqueous phase oxidation of effluents, consisting of subjecting the effluents to oxidation in the presence of at least one oxidizing agent inside a reactor having a gaseous phase set up above a liquid phase consisting of the effluents, and subjecting the gaseous phase to catalysis in the presence of at least one heterogeneous catalyst. The oxidation process is carried out at a temperature of between approximately 20.degree. C. and approximately 350.degree. C. under a pressure of between approximately 1 and 160 bars. At least a part of the organic matter and total ammoniated nitrogen contained in the effluents are mineralized. The process includes recycling at least a part of the gaseous phase present in the oxidation reactor after the gaseous phase has passed through the heterogeneous catalyst so as to effectively increase the contact time between the gaseous phase and the heterogeneous catalyst in order to obtain substantial removal of NH.sub.3, COR, and volatile organic compounds.
