| 摘 要： | 以广东省某垃圾填埋场SBR池活性污泥为接种污泥,以含氮模拟废水为对象,研究了常温条件下UASB-Anammox生物膜反应器的启动情况。结果表明,UASB生物膜反应器运行97d后,NH4+-N和NO2--N的去除效率均可达90%以上,NH4+-N去除量、NO2--N去除量和NO3--N生成量之比为1:1.44:0.26,pH值稳定在8.5左右,污泥由黄褐色转为红褐色,成功启动了厌氧氨氧化反应器。启动成功后,将反应器温度从24℃降至18℃,总氮的去除率依然可以保持90%以上,表明常温下启动运行的厌氧氨氧化生物膜反应器具有良好的温度适应性。 |

| Abstract: | Anaerobic ammonium oxidation ( Anammox) has been deemed as the most simple and economic way to biodenitrification of wastewater. This paper describes start -up of a bench -scaled biofilm UASB installation designed to investigate removal efficiencies of NH4+-N and NO2--N as well as generation of NO3--N at the ordinary temperature of southern China. Result of the experiment of 97 days running of the UASB shows that both of NH4+-N and NO2--N removal efficiencies are above 90%, with pH being stable around 8.5 and the sludge color changed from tawny to red brown. |
