摘要 以硝化污泥为接种污泥,采用含氮模拟废水,在进水pH值为8.0、温度为(30±0.5)℃的条件下运行120 d,成功启动了厌氧氨氧化生物膜反应器。结果表明:在水力停留时间为1.1 d、总氮容积负荷(以N计)为0.109 kg/(m3.d)时,总氮去除率约81.05%,NH4+-N和NO2--N平均去除率分别为86.68%和96.04%,NH4+-N去除量、NO2--N去除量及NO3--N生成量的比值为1∶1.16∶0.30。启动成功后,将反应器停止运行15 d,再以同样条件重新运行,仅用10 d即完全恢复了活性,表明厌氧氨氧化生物膜反应器具有良好稳定性。 When influent pH kept at 8.0 and the temperature kept at(30±0.5)℃,the anaerobic ammonia oxidation(Anammox) bioreactor was successfully started up in 120 days with the nitrification biofilm as inoculum.The results showed,the volumetric total nitrogen loading rate was 0.109 kg/(m3·d),the removal rate of ammonia,nitrite and total nitrogen were 86.68%、96.04% and 81.05%,individually.The ratio of NH+4-N removal,NO-2-N removal and NO-3-N production was 1∶1.16∶0.30.After the bioreactor was stopped 15 days,it took o...
