Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Reinigung von Abwasser, wobei das Abwasser durch eine biologische und eine Denitrifikationsstufe geführt wird und der durch die Betriebsweise bedingte, über die Oberfläche des in der Denitrifikationsstufe befindlichen Abwassers stattfindende Sauerstoffeintrag reduziert wird sowie eine Vorrichtung zur Durchführung eines vorgenannten Verfahrens, umfassend eine biologische Reinigungsstufe und eine Denitrifikationsstufe, wobei bauliche Massnahmen oder der Einsatz von Chemikalien zur Reduzierung des Eintrags von Sauerstoff in die Denitrifikationsstufe vorgesehen sind. Der Vorteil dieses Verfahrens gegenüber den im Stand der Technik bekannten Verfahren ist, dass durch die Reduzierung des Sauerstoffeintrages oder die Reduktion der Sauerstoffverfügbarkeit das Wachstum der filamentösen Mikroorganismen reduziert wird.
