Abstract

L'invention concerne un appareil de digestion aérobie des boues d'égout L'appareil comprend un récipient 1 contenant la boue 2, une canalisation 5 permettant d'amener de l'oxygène jusqu'à une pompe 4 qui envoie de la boue par une buse 6, la buse étant placée de manière que le jet de boue qui en sort agite vigoureusement la boue et répartisse l'oxygène. L'appareil de l'invention assure un mélange efficace de la boue avec l'oxygène sans qu'il soit nécessaire de faire appel à des agitateurs à palettes et il permet d'élever la température de la boue traitée jusqu'à 60 degrés C.
