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, chemical-biological methods were used to improve the phosphorus removal. It was shown that removal efficiency of COD(cr), NH(3)-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.
