摘　　要：通过对厌氧氨氧化污泥投加化学絮凝剂与生物絮凝剂MBFA9,考察其对厌氧氨氧化污泥的沉降性能和脱氮性能的影响。结果表明:添加两种絮凝剂对厌氧氨氧化污泥的沉降性能均有所改善,絮体呈团状。经过11 d连续培养,厌气氨氧化污泥对NH^+_4-N、NO^-_2-N的平均去除率分别为88.13%(对照组为87.38%)、85.40%(对照组为85.44%),而添加化学絮凝对NH^+_4-N、NO^-_2-N去除率最大值分别为39.64%、32.89%。添加生物絮凝剂MBFA9对厌氧氨氧化污泥脱氮性能没有影响,适用于厌氧氨氧化污泥在反应器中的蓄留。Through adding different types of flocculants to anaerobic ammonia oxidation sludge, this study investigated the effect of chemical floceulants and biological floeculants MBFA9 on settleability and denitrification efficiency of anaerobic ammonia oxidation sludge. The experiment＇ results showed that both floeculants improved the settleability of anaerobic ammonia oxidation sludge and the flocculated sludge shaped like a ball. After 11 days of continuous culture, the average removal rates of NH4＋-N and NO2- -N were up to 88.13% （87.38% for the control）, and 85.40% （85.44% for the control）, respectively. However, the maximum removal rates of NH4＋ -N and NO2- -N were just 39.64% and 32. 89% , respectively, when poly-aluminum chloride was added. MBFA9 had no effect on denitrification efficiency of anaerobic ammonia oxidation sludge, which was proved to be suitable for the mantaining of ANAMMOX sludge.
