Study on Denitrification and Phosphorus Removal Using an Integrated A/O Trickling Filter

摘要：

Two columns were experimented to compare trickling filter with integrated A/O trickling filter (IA/OTT) in this study. Denitrification and phosphorus removal were limited in traditional trickling filter. By designing anoxic section, adding carbon source and recycling outflow, denitrification was enhanced in IA/OTT. Meanwhile, chemicalbiological methods were used to improve the phosphorus removal. It was shown that removal efficiency of COD_(cr), NH3-N, TN and TP were ideal. Compared with the traditional trickling filter, especially, the removal efficiency of TN and TP were respectively about 35％ and 50％ higher.
