摘　　要：反硝化除磷工艺是根据反硝化聚磷菌(DPB)的摄磷特点而开发的新型生物脱氮除磷工艺。该工艺以其特有的“一碳两用”和“双泥系统,”有效解决了常规生物脱氮除磷工艺的碳源供求矛盾和泥龄控制问题,可同时获得较高的除磷和脱氮效率,并具有所需曝气量少,剩余污泥排放量低等特点。The denitrifying dephosphatation processes were developed based on the P-uptake capability of the denitrifying phosphorus removal bacteria （DPB） under anoxic condition. The problems of carbon source supply and sludge age control could be effectively solved in the processes by means of ＂one carbon source for two uses＂ and ＂two-sludge system＂, meanwhile phosphorus and nitrogen can be removed with less oxygen requirements and sludge production.
