中文摘要：

在序批式活性污泥反应器（SBR）中，以模拟城市污水为处理对象，研究了短程硝化和以NO2-—N为电子受体的反硝化除磷过程特征及处理效果．试验表明，在SBR反应器中以NO2-—N作为电子受体进行反硝化除磷是完全可行的．在温度为20～25℃，曝气量为30～40L·h-1，pH值为7．0～7．5，MLSS为3000mg·L-1左右的条件下，COD、NIV—N、TN及TP的平均去除率分别达到92％、96％、89％和90％．

英文摘要：

The test researches the characteristics and treatment effects of shortened nitrification and NO2--N as electron acceptor in denitrification and phosphorus removal in sequencing batch reactor （SBR）, with treatment object being simulated the urban sewage. The results show that it is entirely feasible to NO2--N as electron ac- ceptor in shortened denitrification and phosphorus removal in SBR. When temperature is 20 - 25 ℃, aeration is 30-40 L.h-1, pHis7.0-7. 5, MLSS is about 3 000 mg.L-1, the average removal rates of COD, NH4N, TN and TP are 92%, 96%, 89% and 90%.
