Title (EN) METHOD FOR DEPOLLUTING AQUEOUS MEDIA CONTAINING ORGANIC POLLUTANTS
(FR) PROCEDE DE DEPOLLUTION DE MILIEUX AQUEUX CONTENANT DES POLLUANTS ORGANIQUES
Abstract:
(EN) The invention concerns a method for depolluting aqueous media containing organic pollutants. The method aims at reducing chemical oxygen demand and/or total organic carbon of an aqueous medium containing organic molecules. It consists in subjecting the aqueous medium to an electron stream generated by an electron accelerator, in the presence of a catalyst, then in eliminating from the treated solution the formed precipitates, said catalyst comprising a metal ion persulphate, and optionally an Fe(II) salt or and an Fe(III) salt.
(FR) La présente invention concerne un procédé de dépollution de milieux aqueux contenant des polluants organiques. Le procédé vise à diminuer la DCO et/ou le COT d'un milieu aqueux contenant des molécules organiques. Il consiste à soumettre le milieu aqueux à un faisceau d'électrons généré par un accélérateur d'électrons, en présence d'un catalyseur, puis à éliminer de la solution traitée les précipités formés, ledit catalyseur comprenant un persulfate d'ion métallique, et éventuellement un sel de Fe(II) ou un sel de Fe(III).
