Abstract
A device for treating waste water with UV-radiation is in the form of an upwardly open channel with a bottom surface and two vertical side walls, which includes a UV-irradiation chamber and a downstream outlet chamber adjoining the UV chamber. UV-radiation sources are installed in the irradiation chamber. A damming wall terminating the outlet chamber is in the form of an extension of the channel bottom raised upwardly in a slanted way at a flat angle to the direction of flow. A multitude of tubes extending perpendicular to the direction of flow of the waste water are present on the slanted damming wall. These tubes are open at both ends. The top ends of the tubes form overflow edges for the waste water. The damming wall has openings in the locations where the tubes are secured on the damming wall. These openings correspond to the cross sections of the tubes, so that the waste water flowing across the overflow edges of the tubes can drain off through the openings.
