Abstract

L'invention concerne le traitement d'un effluent industriel aqueux. L'effluent est traité dans une volume 1 par de l'oxygène diffusé en 4 dont la concentration dans l'effluent reste inférieure à la moitié de la saturation; la pression du gaz dans le ciel est inférieure à 10 bars absolus; la température de l'effluent se situe entre 20 et 80 degrés C. Application au traitement d'eau contenant des sulfures.
