Abstract

L'INVENTION CONCERNE UN PROCEDE DE TRAITEMENT D'EAUX USEES BRUTES POUR ELIMINER LES IMPURETES ET EFFECTUER LA NITRIFICATION AVEC UNE EFFICACITE SANS PRECEDENT. DES EAUX USEES BRUTES ET DU CHARBON VIERGE NEUF SONT MELANGES EN 2 PUIS AMENES DANS UN REACTEUR 3 D'AERATION BIOLOGIQUE CONTENANT DU CHARBON ACTIVE ET DE LA BIOMASSE QUI SONT ENSUITE SEPARES DANS LE CLARIFICATEUR 4 POUR OBTENIR UN EFFLUENT 5 ET UNE SUSPENSION EPAISSIE 6. CETTE SUSPENSION DE CHARBON ET DE BIOMASSE EST ENSUITE SOUMISE A UNE OXYDATION PAR VOIE HUMIDE DANS DES CONDITIONS DETERMINEES ET LA SUSPENSION OXYDEE RESULTANTE EST RECYCLEE A LA ZONE DE BIOTRAITEMENT POUR TRAITER D'AUTRES EAUX USEES.
