Abstract

Es ist ein Verfahren zur Behandlung von Abwasser in einem Belebungsbecken bekannt, bei dem ein sauerstoffhaltiger Gasstrom unter Einsatz mindestens eines länglichen Schlauchausströmers (1) in das zu behandelnde Abwasser eingeleitet wird. Um hiervon ausgehend ein Verfahren zur Verfügung zu stellen, mittels dem eine bessere Sauerstoffausnutzung durch nachträgliche Optimierung von Blasengrösse und Gasdurchsatz ermöglicht wird, wird erfindungsgemäss vorgeschlagen, dass der Schlauchausströmer (1) im Abwasser fortwährend bewegt wird. Eine zur Durchführung des Verfahrens geeignete Vorrichtung umfaßt einen Ausströmöffnungen aufweisenden, länglichen Schlauchausströmer (1) zur Einleitung eines sauerstoffhaltigen Gasstroms in das zu behandelnde Abwasser, und eine mit dem Schlauchausströmer (1) verbundene Zufuhrleitung (3) für die Zufuhr des sauerstoffhaltigen Gasstroms, wobei der Schlauchausströmer (1) mit einer, einen Antrieb (4) umfassenden Bewegungseinrichtung (2; 3; 4) verbunden und im Abwasser fortwährend bewegbar ist.
