Abstract
L'invention décrit un procédé et un appareil de traitement d'oxygénation, dans un seul bassin, d'eaux-vannes ou d'autres matières résiduaires aqueuses. La matière résiduaire, que contient le bassin de traitement, se divise d'elle-même en une couche supérieure de liquide clarifié et une couche inférieure de liquide contenant de la boue activée. Du liquide provenant de cette dernière couche est combiné avec de la matière résiduaire affluente et le mélange résultant est refoulé dans une chambre d'oxygénation où O2 se dissout dans le liquide Le liquide oxygéné résultant entre dans une chambre de tranquillisation disposée dans la couche supérieure. Le liquide clarifié se déverse du bassin. Application du traitement des eaux-vannes domestiques ou urbaines des matières résiduaires aqueuses industrielles ou d'autres effluents tels que ceux provenant d'une papeterie.
