Abstract (en)
[origin: WO0132567A1] The invention concerns a method for purifying aqueous effluents containing in particular peroxidized compounds. More particularly, it concerns a method for purifying aqueous effluents comprising an anaerobic biological decomposition of compounds contained in the effluents. The effluents are treated, prior to their anaerobic biological decomposition, in a deperoxidizing step to reduce the peroxide concentration and prevent harmful effects of said compounds on the enzymes or bacteria.
