采用深床生物滤池对东港污水处理厂的出水进行深度脱氮处理，出水DO控制在1 mg/L以下，HRT=2 h，乙酸钠投加质量浓度在0.1 g/L，经深床滤池处理后，TN 可被消除40%～60%，出水实现NH3-N＜5 mg/L，TN＜15 mg/L的目标。在5～15℃的低温运行区间，深床滤池仍然可以实现对TN的有效去除。

The deep-fixed bed filtration proce ss (DFB) has been applied to the advanced denitrification treatment of the effluent from Donggang Sewage Treatmeat Plant. When the DO of effluent is controlled at less than 1 mg/L , HRT=2 h,and sodium acetate=100 mg/L,40%-60%of the TN in effluent after the treatment can be removed. The result of effluent NH3-N<5 mg/L,and TN<15 mg/L can be achieved. On the other hand,it is found that efficient re-moval can still be achieved by using the deep-fixed bed filtration process,when it runs at low temperature( 5-15℃).
