A cost-effective broad temperature method for removing troublesome low valent sulfur compounds from aqueous streams. The process utilizes sulfur dioxide, oxygen and at least one metal catalyst (which may be added to or already entrained in the aqueous stream) to oxidize the low valent sulfur compounds.

L'invention concerne un procédé économique à températures variées permettant d'éliminer de flux aqueux, des composés de soufre de faible valence qui sont une source de problèmes. Ledit procédé utilise du dioxyde de soufre, de l'oxygène et au moins un catalyseur métallique (que l'on peut ajouter à un flux aqueux ou qui est déjà entraîné dans ce flux aqueux), de manière à oxyder les composés de soufre de faible valence.
