Abstract

La présente invention se rapporte à des perfectionnements aux procédés d'épuration d'eaux résiduaires. Le procédé est caractérisé en ce qu'on libère les composés ammoniacaux non volatils dans une première zone de la colonne, les composés phénolés dans une deuxième zone et les composés ammoniacaux volatils dans une troisième zone de la colonne de stripping, la zone où s'effectue l'élimination des composés phénolés étant disposée de telle façon dans la colonne qu'aucune vapeur ammoniacale ne puisse la traverser. Application à la purification des eaux résiduaires de cokerie.
