Kurzbeschreibung (Abstract)
Two single stage deammonification reactors, one Sequencing Batch Reactor (SBR) and one Moving Bed Biofilm Reactor (MBBR) were operated to study their applicability for treatment of industrial wastewaters with high C : N ratios. The performance of both systems was evaluated changing the influent from municipal reject water (C : N ratio 1 : 1) stepwise to an industrial wastewater (C : N ratio 3 : 1). An intentionally induced temperature drop was also tested. The results showed that the MBBR (1.9 kg-N m –3 d –1 ) was superior to the SBR (0.5 kg-N m –3 d –1 ) with at maximum up to 4 times higher volumetric nitrogen removal rates. Both systems accumulated nitrite (>100 mg-N L –1 ) during the temperature drop from 30 °C to around 20 °C, which subsequently resulted in almost complete loss in the removal capacities. However, both systems were able to re-establish their previous removal rates within approx. 20–40 days. Overall, the MBBR showed the more stable and better performance.
