Abstract [en]

Degradation of nitrogen containing organic compounds often leads to formation of ammonium and low molecular weight organic compounds. The study is focuseed on degradtion of acetonitrile in a sequence of stirred biofilm reactors, where degradation of acetonitrile to acetic acid and ammonia takes place in the first two reactors. A large fraction of the acetic acid is also degraded in these reactors. The subsequent two reactors were introduced in order to take care of the ammonia, while a fifth reactor was a polishing step before the water was released to the recipient. From earlier studies it is known that the rate of acetonitrile degradation is approximately 80 g acetonitrile/(m3 reactor h). This means that the reactors involved in remval of the nitrogen component needs to be far larger than those dealing with degradation of the more complex molecules.
