摘　　要：鉴于反硝化菌与厌氧氨氧化菌具有相似的生理特性,采用CSTR反应器研究了以异养反硝化污泥启动厌氧氨氧化系统的可行性,并考察了其对高氨氮废水的处理潜能。反应器运行170 d后,试验结果表明,此方法可快速培育出具有厌氧氨氧化活性的污泥,NH_4^+-N和NO_2^--N的去除率分别可达99.20%和99.69%。在此基础上考察了有机物浓度对厌氧氨氧化性能的影响,结果表明:低浓度(ρ(COD)≤150 mg/L)有机物可促进厌氧氨氧化活性,而高浓度(ρ(COD)≥200 mg/L)有机物抑制厌氧氨氧化进程,该系统最适ρ(COD)/ρ(NH_4^+-N)为2.14,此时NH_4^+-N和NO_2^--N的去除率分别为99.41%和99.65%。According to the characteristic of denitrification bacteria and anaerobic ammonia oxidation（ Anammox） bacteria,a continuous stirred-tank reactor was used to cultivate Anammox sludge with inoculating denitrifying sludge. The feasibility of using denitrifying sludge to start-up Anammox was investigated and the the denitrification effect on high ammonia concentration wastewater was reviewed. After 170 days,the removal rate of ammonia and nitrite achieved 99. 20%,99. 69% respectively. Furthermore,the effect of COD concentration on Anammox was investigated. The results showed that low COD concentration（ ≤ 150 mg / L） promoted the Anammox activity,and high COD concentration（ ≥ 200 mg / L）restrained the Anammox activity. The removal rate of ammonia and nitrite achieved 99. 41%,99. 65% respectively at an optical COD / NH_4~＋-N of 2. 14.
