Abstract

Le secteur technique de l'invention est celui du traitement des eaux résiduaires, en vue d'en éliminer les caractères nocifs. L'invention concerne un procédé et un appareillage de traitement d'eaux résiduaires, notamment par voie biologique, caractérisés par le fait que lesdites eaux résiduaires, en continu, après décantation de boues, sont chargées en oxygène, le liquide dans lequel l'oxygène est dissous étant l'objet d'un traitement aérobie de dégradation des charges, d'un traitement aérobie de transformation des substances azotées subsistantes en nitrates puis, après dégazage, d'un traitement en anoxie de décomposition des nitrates. Application au traitement souple des eaux résiduaires sous variations notables de composition et de quantité.
