Title
(DE) EINRICHTUNG FÜR DIE BIOLOGISCHE ABWASSERREINIGUNG
(EN) DEVICE FOR BIOLOGICAL WASTEWATER TREATMENT
(FR) DISPOSITIF D'EPURATION BIOLOGIQUE D'EAUX USEES
Abstract
(DE)
Eine Vorrichtung zur biologischen Reinigung von Abwässern, insbesondere Spülabwässern aus kleinen, lokalen, an das Kanalisationsnetz nicht angeschlossenen Hausobjekten, ist mit mindestens einem mechanische Verschmutzungen auffangenden Fänger (5), einem Aktivierungsraum, einem sich nach oben hin erweiternden Trennraum (3) für die Fluidfilterung und einem Innenzirkulationskreislauf zwischen einzelnen Beckenräumen versehen. Gemäß der Erfindung ist eine in unmittelbarer Nähe des Beckenbodens mit mindestens einem Luftmischer (14) versehene, anoxide Zone (21) des Aktivierungsraums von einer mit mindestens einem Luftsprudler (18) versehenen, oxiden Zone (22) des Aktivierungsraums völlig getrennt. Der Trennraum (3) ist in unmittelbarer Nähe des Beckenbodens mit einem im Bereich einer Trennwand des Beckens gebildeten Entgasungsraum (4) verbunden, wobei in der anoxiden Zone (21) eine Vorrichtung zur Wasserspiegelregelung mündet.
(EN)
A device for biological treatment of wastewater, especially rinsing water arising from small-sized domestic objects that are not connected to the drainage network. The inventive device is provided with at least one mechanical collector (5) which collects mechanical pollutants, an activation chamber, a separating area (3) for fluid filtration that expands in an upwards direction and an inner circulation circuit between individual basin areas. According to the invention, an anoxide area (21) of the activation chamber which is provided with at least one air mixer (14) and is located in the immediate vicinity of the bottom of the basin is fully separated from an oxide area (21) of the activation chamber which is provided with an air swirling device (18). The separation area (3) is located in the immediate vicinity of the bottom of the basin and connected to a degasification chamber (4) formed in an area of a separating wall pertaining to the basin. A water level adjustment device discharges into the anoxide area (21).
(FR)
L'invention concerne un dispositif d'épuration biologique d'eaux usées, notamment d'eaux usées de rinçage provenant d'appareils domestiques locaux de petite taille, non reliés au réseau d'égouts. Ce dispositif comprend au moins un collecteur (5) de salissures mécaniques, une chambre d'activation, une chambre de séparation (3) s'évasant vers le haut, prévue pour la filtration fluidique et un circuit de circulation intérieure entre des cuves individuelles. Selon l'invention, une zone inoxydée (21) de la chambre d'activation, qui est munie d'un mélangeur d'air, à proximité immédiate du fond de la cuve, est entièrement séparée d'une zone oxydée (22) de la chambre d'activation, qui est munie d'un dispositif de tourbillonnement d'air (18). La chambre de séparation (3) est reliée, à proximité immédiate du fond de la cuve, d'une chambre de dégazéification (4) formée dans la zone d'une paroi de séparation de la cuve. Un dispositif de régulation du niveau d'eau débouche dans la zone inoxydée (21).
