Abstract

On met le liquide en contact, si nécessaire après séparation de composants ou de constituants séparables, dans un espace de traitement, avec des micro-organismes présents dans cet espace et en alimentant avec un gaz contenant de l'oxygène et dans lequel les micro-organismes et les produits réactionnels présents dans le liquide sont séparés par sédimentation de ce liquide. Dans la paroi latérale du bassin ou près de cette paroi latérale, on a prévu un point de soutirage 7 qui est relié par l'intermédiaire d'une vanne 8 à un conduit de décharge 9. Au-dessus de l'ouverture 7, un second point de soutirage 7' est indiqué par une ligne à traits interrompus, qui au moyen d'une vanne 8' est relié également au conduit 9. Le nombre de ces points de soutirage superposés n'est pas limité à deux. S'il existe plus d'une ouverture 7, on peut effectuer un soutirage à différents niveaux comme on le desire. Application au traitement des eaux résiduaires.The liquid is brought into contact, if necessary after separation of components or separable constituents, in a treatment space, with microorganisms present in this space and supplying with a gas containing oxygen and in which the micro- organisms and reaction products present in the liquid are separated by sedimentation of this liquid. In the side wall of the basin or near this side wall, there is provided a draw-off point 7 which is connected via a valve 8 to a discharge pipe 9. Above the opening 7, a second draw-off point 7 'is indicated by a dotted line, which by means of a valve 8' is also connected to the pipe 9. The number of these superimposed draw-off points is not limited to two. If there is more than one opening 7, a draw-off can be carried out at different levels as desired. Application to the treatment of waste water.
