Abstract

L'invention concerne un procédé de traitement biologique, de matières oxydables contenues dans un milieu liquide. Il consiste à faire circuler le liquide à traiter 1 sur un lit bactérien 3 au contact d'un gaz oxydant 18-22 délivré à une pression partielle de O2 minimum et en quantité appropriée puis à soumettre le liquide résultant de ce premier traitement à un traitement en << boues activées >> 13 sous l'action d'un gaz plus riche en oxygène 15, l'atmosphère gazeuse 18 résultant de ce second traitement étant envoyée au premier stade de traitement pour servir en totalité ou en partie de gaz de traitement de ce premier stade. Application à l'épuration des eaux usées.
