Abstract
The present invention relates to a method of purifying aqueous effluents containing in particular peroxidized compounds.It relates more particularly to a method of purifying aqueous effluents comprising a method of anaerobic biological decomposition of the compounds contained in the effluent. The effluents are treated prior to their anaerobic biological decomposition, in a deperoxidation step in order to reduce the concentration of peroxide and to avoid the harmful effect of these compounds on the enzymes or bacteria.
