Abstract

A.PROCEDE D'OXYDATION PAR VOIE HUMIDE DES POLLUANTS. B.CE PROCEDE SE CARACTERISE EN CE QUE L'OXYDATION EST EFFECTUEE AU MOYEN D'OXYGENE LIQUIDE, EVENTUELLEMENT ADDITIONNEE D'OZONE ET DE SUBSTANCES ORGANIQUES. C.TRAITEMENT DES EAUX ET BOUES RESIDUAIRES INDUSTRIELLES.A.PROCESS OF WET OXIDATION OF POLLUTANTS. B. THIS PROCESS IS CHARACTERIZED IN THAT THE OXIDATION IS CARRIED OUT BY MEANS OF LIQUID OXYGEN, POSSIBLY ADDITIONED WITH OZONE AND ORGANIC SUBSTANCES. C. TREATMENT OF INDUSTRIAL WASTE AND SLUDGE.
