Abstract: front page image
(EN)A new and useful way of treating oxidized-contaminant-containing water, soil, rock, other geological or non-geological matrix formation (such as a landfill) is provided. A bioreactor is provided that includes elemental sulfur and a microbial population capable of oxidizing sulfur and reducing pertechnate (TcO4'), arsenate (H2AsO4'), chromate (CrO42'), bromate (BrO3'), chlorite (ClO2'), chlorate (ClO3'), perchlorate (ClO4'), and uranium(VI) oxide, with biological reduction of these oxidized contaminants in the matrix containing the oxidized contaminant performed by the bioreactor, with the elemental sulfur as the electron donor.
(FR)L'invention concerne une nouvelle manière utile permettant de traiter de l'eau, un sol une roche, ou une autre formation matrice géologique ou non-géologique (telle qu'une décharge) contenant un contaminant oxydé. L'invention concerne également un bioréacteur comprenant un soufre élémentaire et une population microbienne capable d'oxyder un soufre et de réduire un pertechnate (TcO4), un arsenate (H2AsO4), un chromate (CrO42), un bromate (BrO3), un chlorite (ClO2), un chlorate (ClO3'), un perchlorate (ClO4') et un oxyde d'uranium (VI) avec réduction biologique des contaminants oxydés dans la matrice contenant lesdits contaminants oxydés réalisée par le bioréacteur, le soufre élémentaire étant un donneur d'électrons.
