<p>The waste water treatment is realised in such a way that the waste water after the optional removal of coarse materials and/or the waste water from the adjoined anaerobic area (17) is recycled in the activation tank (1) through the oxic and anoxic part of the activation by the means of escaping air bubbles created after the air loading into the aeration device (8). At the same time sediments are washed away from the sedimentation tank (2). By the means of the optional creation of the water jump (10) onto the slot (7) by the appropriate velocity of the recycled water and air escaping from the aeration device (8) the activation mixture is pumped into the sludge area or the anaerobic area in the case of phosphorus removal. The cleaned waste water is discharged via the collection channel (11) into recipient. The aero-selector for waste water treatment consists of cylindrical, horizontal activation tank (1) on which the sedimentation tank (2) is connected whose bottom part opens radially into the lower part of the activation tank (1) and this opening area is adapted for the sedimentation degassing. The activation tank (1) is inside equipped with the aeration device (8) for the recycling and aeration of the activation mixture and with an upper opening (5) created along the activation tank (1) in the highest point of its wall. The slot (7) created between the inner wall of the activation tank (1) and the plate-shaped part (6) can end in the opening (5). The activation tank (1) can be equipped with a sludge carrier (9) of cylindrical shape with at least one opening.</p> |
