摘　　要： 采用预培养的混合污泥作为接种污泥,接种于上流式厌氧污泥床反应器（UASB）来启动厌氧氨氧化,结果表明：采用含氮模拟废水,进水pH控制为7.00～7.40,在30℃条件下,运行52 d,成功启动了UASB厌氧氨氧化反应器.反应器的容积总无机氮（TIN）负荷为3.26 kg/（m^3·d）,去除率达到90.85％.稳态运行时,NH4＋-N去除量、NO2--N去除量与NO3--N生成量的比值为1.00∶ 1.22∶0.15.启动过程中,在水力负荷与进水基质负荷不稳定的情况下,反应器出水效果良好,说明其具有较好的稳定性.NH4＋-N去除量、NO2--N去除量与NO3--N生成量的比值变化可指示厌氧氨氧化反应器性能的演变. The precultured sludge was used as the seeding sludge to start up anammox in UASB reactor. The synthetic wastewater contained nitrogen was used in the experiment. When pH of influent kept at 7. 00-7. 40, and reaction temperature kept at 30℃ the UASB anammox reactor was successfully started up in 52days.The volumetric total inorganic nitrogen （TIN） loadingwas 3. 26 kg/（m3·d） in the reactor, and TIN removal rate was 90. 85%. At the steady state, the ratio of removed NH;-N, removed NOE--N and produced NO3--N was 1.00 ： 1.22 ： 0. 15. In the start-up process, the reactor operated well under the instable hydraulic and influent loading, which indicated the reactor had an excellent stabilizatiorL The ratio of removed NH4^＋-N, removed NO2^- -N and produced NO3^- -N could indicate the performance of anammox reactor.
