| 摘 要： | 目的]研究内循环撞击流生物膜反应器处理高浓度氨氮废水的性能。方法]采用内循环撞击流生物膜反应器,以玉米芯为生物载体处理模拟高氨氮废水,探讨了C/N比、溶解氧（DO）对COD和NH4＋-N去除效果的影响。结果]在进水NH4＋-N 200 mg/L、DO 2mg/L、C/N比分别为1.0和1.5时,对COD的去除效果没有明显影响,均高达92%以上;C/N为1.5时,COD和NH 4＋-N平均去除率最高,分别达92.7%和41.2%;在C/N为2.0时,去除率显著降低,COD和NH4＋-N平均去除率分别降至20%和10%左右;在C/N为1.5、NH 4＋-N 200 mg/L时,DO对COD的去除影响不大,但对NH 4＋-N的去除影响较大,DO浓度从4 mg/L降到1 mg/L时,NH 4＋-N去除率从46.4%降至17.1%。结论]该研究为高氨氮废水处理提供了理论依据。
