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.
A invenção atual relaciona-se a um método de purifying os effluents aqueous que contêm em compostos peroxidized particulares. Relaciona-se mais particularmente a um método de purifying os effluents aqueous que compreendem um método do decomposition biológico anaerobic dos compostos contidos no effluent. Os effluents são tratados antes de seu decomposition biológico anaerobic, em uma etapa do deperoxidation a fim reduzir a concentração do peroxide e evitar o efeito prejudicial destes compostos nos enzymes ou nas bactérias.
