Patentansprüche
1. Verfahren zur Steuerung der Belüftung bei einer biologischen Abwasserbehandlung unter Durchführung einer aeroben Entkarbonisierungphase, einer aeroben Nitrifizierungsphase und einer anaeroben Denitrifizxerungphase, wobei bei dem Verfahren ständig das Redoxpotential in einem Behandlungssystem gemessen, die Kurve der Entwicklung des Redoxpotentials als Funktion der Zeit aufgenommen und deren Ableitung berechnet wird, dadurch gekennzeichnet , daß man, wenn die Ableitung gegen Null geht, die Ableitung und den Wert des Redoxpotentials korreliert, um den Beginn, die Fortsetzung oder die Stillsetzung der Belüftung zu bestimmen.
2. Verfahren nach Anspruch 1,
dadurch gekennzeichnet , daß man die Belüftungsdauer unter Berücksichtigung der vorhergehenden Ereignisse bestimmt, wobei die Belüftungsdauer die Zeit, die nötig ist, um das Redoxpotential auf den erforderlichen Wert zu bringen, plus die zusätzliche Zeit, die zum Durchführen der Belüftung nötig ist, umfaßt.
