Abstract

La présente invention concerne des systèmes auto-régulateurs destinés au traitement biologique poussé des eaux usées domestiques au moyen de boues activées en suspension. Ce procédé consiste à déterminer au préalable des intervalles de temps de deux phases alternées de fonctionnement du dispositif en fonction de la composition des eaux usées. La première phase de fonctionnement du dispositif comprend l'aération d'une cuve de stabilisation de la boue et d'une cuve d'aération puis l'actionnement d'un aérateur à grosses bulles de l'unité de soufflage externe d'un puits tubulaire en vue du mélange de l'eau et de la boue dans un réservoir d'activation et de l'introduction de ce mélange dans la cuve d'aération. La deuxième phase comprend l'aération d'un réservoir d'équilibrage et du réservoir d'activation ainsi que l'actionnement de pompes de recirculation et de circulation de boue et d'eau, d'une pompe d'extraction et d'un aérateur-désintégrateur servant à rompre une pellicule biologique en vue de la recirculation de la boue et du nettoyage d'un décanteur secondaire. Cette invention permet d'obtenir des eaux usées épurées de grande qualité pouvant être réutilisées et de réduire la consommation d'énergie nécessaire à l'intensification de l'épuration.
