Case 3281 Patentansprüche
1. Verfahren zur anaeroben Behandlung von Abwasser aus der Herstellung von mechanischer oder chemi-mechanischer Cellulosepulpe, bei dem das Abwasser in zumindest zwei anaeroben Stufen, nämlich einer Hydrolyse- und sauren Fermentationsstufe (2) und einer Methanfermentationsstufe (3), woran sich eine aerobe Stufe (5) anschließt, behandelt wird, dadurch gekennzeichnet, daß Peroxid in dem eintretenden Abwasser in einer enzymatischen Vorstufe (1) im wesentlichen zerstört wird.
2. Verfahren gemäß Anspruch 1, dadurch gekennzeichnet, daß die Enzyme für die enzymatische Stufe (1) in der aeroben Stufe (5) gebildet werden.
3. Verfahren gemäß Anspruch 1, dadurch gekennzeichnet, daß die Enzyme für die enzymatische Stufe (1) in der Hydrolyse- und sauren Fermentationsstufe (2) gebildet werden.
4. Verfahren gemäß Anspruch 1, daß die Enzyme aus Gatalase bestehen.
5. Verfahren gemäß Anspruch 1, daß das Redoxpotential der Hydrolyse- und sauren Fermentationsstufe (2) kontinuierlich kontrolliert werden und der Wert für die Regulierung der Überführung des Schlamms zu der enzymatischen Vorstufe (1) verwertet wird.
