Abstract

L'invention concerne un procédé d'introduction en continu de gaz oxygénés, d'air enrichi en oxygène ou d'oxygène dans des boues activées contenant des eaux résiduaires, ou dans des bouillons de fermentation, l'oxygène étant pratiquement utilisé en totalité par les boues résiduaires ou les bouillons de fermentation. On introduit le gaz dans la phase liquide se trouvant sous sa propre pression hydrostatique, à des endroits ou règne une pression hydrostatique de 0,9 à 3 bars, la pression du gaz introduit étant de 0,01 à 0,5 m d'eau au-dessus de la pression hydrostatique au niveau de l'entrée de gaz. On utilise des injecteurs à jet liquide.
