Abstract

Procédé de digestion des boues résultant notamment du traitement des eaux usées. Il consiste à digérer les boues par oxygénation dans une première zone fermée, à une température de 45 à 75 degrés C, puis à soumettre les boues partiellement stabilisées, provenant de ces zones, à une digestion anaérobie dans une seconde zone fermée, à une température de 30 à 60 degrés C. Domaine d'application : évacuation des eaux usées.
