Influence Factors of Nitrogenous Heterocyclic Compound–Pyridine Degradation under Anozic Conditions

摘要：

The anoxic degradation and removal of nitrogenous heterocyclic compound-pyridine and the effect of pH, C/N ratio, bio-ferric on degradation of pyridine were studied by flaskshaking tests. The results indicate that pyridine was removed through three steps. They are biosorption-desorptionbiodegradation. The optimal range of pH was 7～9. The C/ N ratio was not affecting the reduction of pyridine greatly. Bio-ferric process can increase the degradation of pyridine, the best concentrations of bio-ferric was 5mg/L. pyridine could used as the sole carbon and nitrogen sources for biodegradation.
