Abstract

Un système d’optimisation de la capacité d’aération d’une station d’aération d’un bassin d’épuration à boues activées, station qui comprend  au moins  un  appareil   d’injection d’oxygène dans le bassin d’épuration,  appareil qui est un appareil flottant,  comprenant les éléments  suivants :   un dispositif d'entraînement, destiné à être disposé au-dessus du liquide,   pourvu d'un arbre   de sortie vertical ou incliné,  équipé à son extrémité d’ au moins un mobile de mélange et de dispersion du gaz injecté  tel qu'une hélice tripales , caractérisée par son diamètre D ;   un  dispositif d’injection du gaz, positionné  par exemple au-dessus   du mobile  ; se caractérisant  en ce que afin de rendre la station   apte à traiter un  pic de pollution,  que ce soit en terme de débit d’effluent parvenant à la station et/ou de teneur en pollution de l’effluent parvenant à la station, on  augmente le diamètre du mobile d’au moins un desdits appareils, pour augmenter sa capacité et donc repousser sa limite d’engorgement, l’augmentation  du diamètre  étant  préférentiellement située  dans la gamme  allant jusqu’à +20% du diamètre initial .
