Abstract

Abstract: The purpose of this research is to study the nitrogen removal rate of municipal wastewater after the treatment of biological aerated filter（BAF） in the condition of different carbon resources(CH₃OH, CH₃COONa,C₆H₁₂O₆). The research shows that when C/N is 3∶1~4∶1, velocity is 1.0 m/h, the additional carbon resource has a significant effect on denitrification rate in anoxic filter. The biochemical characters of CH₃OH and CH₃COONa are similar when they are used as the carbon resource, and these two resources result in quite efficient denitrification. However, using C₆H₁₂O₆ as the additional carbon resource leads to lower nitrogen removal rate when compared with these two mentioned sources.

Key words: anoxic biological filter, domestic sewage, carbon resource, denitrification
