Abstract

Procédé biologique de traitement d'air vicié caractérisé en ce que l'on fait passer l'air vicié à traiter à travers deux biolaveurs (2, 18) montés en série, le premier biolaveur (2) fonctionnant à pH basique compris entre 7,5 et 8, le deuxième biolaveur fonctionnant à pH acide compris entre 4,5 et 5. Le procédé comporte une étape de dépoussiérage intégrée via une raquette de répartition immergée dans une solution de recirculation (3) au sein du premier biolaveur. Le procédé comporte deux biofiltres bactériens munis d'un garnissage neutre (4) ainsi qu'une ligne de recirculation permettant une injection de nutriments, d'acide chlorhydrique (10) et de lait de chaux (9). L'injection de réactifs est contrôlée par une analyse en continu du pH et du potentiel redox. Le procédé comprend pour chaque étape de traitement un dispositif de fluidisation du lit contrôlé par mesure de perte de charge différentielle (12).
