Abstract
L'invention concerne un appareil de mélange et de digestion pour le traitement biochimique de fluides résiduaires. Ledit appareil comporte un récipient formant une chambre de mélange au centre de laquelle se trouve un diffuseur qui dirige les fluides résiduaires radialement vers l'extérieur. Un collecteur entoure concentriquement le diffuseur et est relié à une pompe de recyclage refoulant une partie des fluides résiduaires dans un circuit de recyclage. Une buse d'injection est montée dans le fond du récipient pour mélanger aux fluides recyclés de l'air favorisant le développement des bactéries. Une chicane coopère avec la buse d'injection pour provoquer une forte turbulence dans la chambre de mélange. Application à la digestion rapide de fluides résiduaires par contact avec une culture bactérienne aérobie pour le traitement d'eaux d'égout, de déchets industriels, etc
