Abstract

The anoxic degradation and removal of nitrogenous heterocyclic compound-dimethlypyridine, and the effect of pH, C/N ratio, bio-ferric on degradation of dimethylpyridine were studied by flask-shaking tests. The results indicate that dimethylpyridine was removed through three steps. They are biosorption-desorption-biodegradation. The optimal range of pH was 7~8. The C/N ratio was not affecting the reduction of dimethylpyridine greatly. Bio-ferric process cannot increase the degradation of dimethylpyridine; Dimethylpyridine could use as the sole carbon and nitrogen sources for biodegradation.
