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、NO_2~--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 achieved. The start-up period can be divided into three main phases, namely, the lag phase, the acclimatization phase and the steady phase. In the steady phase, the removal efficiencies of NH_4~+-N, NO_2~--N,TN and COD are 95%, 99%, 94% and 93% respectively. The ratio of NH_4~+-N removal to NO_2~--N removal to NO_3~- N production is 1:1.32:0.03, and the effluent alkalinity and pH are slightly higher than those of the influent.
