摘要(Abstract)：

以序批式动态膜反应器为研究对象,对其处理低碳氮比废水的效果进行了试验研究。试验温度为19²1℃,MLSS为321℃,MLSS为3⁵ g/L;好氧阶段溶解氧质量浓度为25 g/L;好氧阶段溶解氧质量浓度为2⁴ mg/L,厌氧阶段溶解氧质量浓度为0.24 mg/L,厌氧阶段溶解氧质量浓度为0.2⁰.5 mg/L;水力停留时间共12 h,其中好氧阶段8 h,厌氧阶段4h。结果表明:当进水COD、TN和NH+4-N质量浓度分别为2500.5 mg/L;水力停留时间共12 h,其中好氧阶段8 h,厌氧阶段4h。结果表明:当进水COD、TN和NH+4-N质量浓度分别为250³00mg/L、103300mg/L、103¹56 mg/L和92156 mg/L和92¹40 mg/L时,反应器对上述污染物表现出较高且稳定的去除效率,COD、TN和NH+4-N平均去除率分别达到76.15%、82.16%和90.13%。同时,反应器系统中污泥的比硝化速率与常规处理装置中的活性污泥相比较高,以NH+4-N的降解量计为0.101 d-1,以NO-3-N的积累量计为0.091 d-1。
