<p>Device for biological cleaning of sewage, particularly waste water from small local residential buildings not connected to the sewerage network, containing in one tank at least a collector (5), activation space (2), upwards expanding separation space (3) for fluid filtration, and inner circulation ring between individual spaces of the tank (1). The principle of the invention is that on the one hand an anoxide zone (21) of the activation space (2), equipped on the floor (101) of the tank (1) with at least one air mixer (14), is completely separated from the oxide zone (22) of the activation space (2), equipped with at least one aerator (18), and on the other hand the separation space (3) is, on the floor (101) of the tank (1), fitted with a degassing space (4), created in the area of the dividing wall (17) along the mantle of the tank (1), where the first air-lift pump (7), which is drained above the activation space (2), opens on the floor (101) of the tank (1) in the degassing space (4). The second air-lift pump (12) opens in the anoxide zone (21) and it is connected with the control float piping (13) of the activation space and is drained in the oxide zone (22) of the activation space (2).<IMAGE></p> |
