摘　　要：对AOMBR(缺氧好氧膜生物反应器)处理高氨氮废水的脱氮效能进行了研究,着重考察了硝化效能的稳定性及影响系统稳定运行的因素。研究结果表明:在适宜的pH、DO和温度下,容积负荷<1.5kgNH3-N/(m3·d)时,硝化率可保持在99%以上;好氧池中DO>1.5mg/L能满足硝化需要;好氧池pH维持在6.8～7.2时可稳定高效地去除氨氮;碱度、污泥龄等也会对硝化效率产生影响。在好氧池中硝化率较高的情况下,影响反硝化效果主要是回流比和碳源。Nitrification and denitrification performance of anoxic/aerobic membrane bioreactor （AOMBR） treating high-loading ammonia nitrogen wastewater was studied. The main attentions are laid on the stabilization and influent factors of nitrification performance. The experimental results showed that the removal rate of NH3-N was 99% or more when NH3-N volumetric loading rate was maintained under 1.5 kgNH3-N/（m^3 · d）. In time when DO 〉 1.5 mg/L in aerobic tank, the nitrification can realize commendably. When pH was maintained in range of 6.8-7.2, AOMBR can remove ammonia nitrogen stably. The removal rate of NH3-N was also affected by alkalinity and sludge age. The main influencing factors of denitrification performance were return flow ratio and C/N when nitrification was accomplished well.
