摘　　要：向成功启动并已稳定运行2年的ANAMMOX反应器中连续添加有机物(葡萄糖),研究ANAMMOX与反硝化协同脱氮反应器的启动特性。结果表明,在短期内(35 d)可成功启动ANAMMOX与反硝化协同脱氮反应器。启动过程可分为迟滞、适应和稳定运行三个阶段,在稳定运行阶段反应器对NH+4-N、NO-2-N、TN和COD的去除率分别高达95%、99%、94%和93%,NH+4-N去除量、NO2--N去除量与NO-3-N生成量的比值为1∶1.32∶0.03,出水碱度和pH均略高于进水。The start-up characteristics of the ANAMMOX/denitrification reactor were investigated by continuous addition of organic matter （glucose） into the ANAMMOX reactor that has been successfully started up and operated stably for 2 years. A fast start-up （35 d） of the reactor was successfully a- chieved. The start-up period can be divided into three main phases, namely, the lag phase, the acclima- tization phase and the steady phase. In the steady phase, the removal efficiencies of NH4＋ - N, NO2- - N, TN and COD are 95%, 99% , 94% and 93% respectively. The ratio of NH4＋ - N removal to NO2 - N removal to NO3 - N production is 1 ： 1.32 ： 0.03, and the effluent alkalinity and pH are slightly higher than those of the influent.
