Abstract

L'invention concerne des perfectionnements à la station d'épuration des eaux usées décrite par le brevet principal. La station comporte une enceinte d'aération-décantation, une entrée des eaux à épurer, une sortie des eaux épurées, au moins une rigole d'évacuation des eaux épurées présentant une surface collectrice importante par rapport aux dimensions en plan de l'enceinte, à l'intérieur de cette dernière, au moins un conduit de liaison entre la rigole et la sortie, et des moyens pour maintenir la rigole en dessous du niveau supérieur des eaux à reprendre et au-dessus du niveau des boues de décantation lors de la reprise. Elle est caractérisée en ce qu'elle comporte des moyens pour injecter à volonté un gaz sous pression dans le conduit de liaison en direction de la sortie, pour créer à l'intérieur de ce conduit un appel des eaux épurées de la rigole vers la sortie. Application à une vidange sans turbulence.
