摘　　要：采用改良的倒置A/O(厌氧/好氧)工艺和活性炭强化的膜生物反应器(MBR)处理活性染料废水。中试结果表明,COD_(Cr)值从1200～2000mg/L稳定降至200mg/L以下,氨氮值从50～80mg/L稳定降至2mg/L左右,总磷值从20～40mg/L稳定降至1mg/L左右,色度从1000～1200倍稳定降至30倍左右。活性炭强化的MBR膜生物反应器在15g/L高污泥浓度下,系统运行稳定,膜污染较轻,通量恒定。Reactive dye effluents are treated with modified reversed A/O process and activated carbon enhanced membrane bio-reactor （MBR）. The pilot results show that the process has good efficiency with the CODc, dropping from ! 200 -2 000 mg/L to below 200 rag/L, NH3-N from 50-80 mg/L to 2 mg/L, TP from 20 -40 mg/L to 1 mg/L and chromaticity from 1 000 -1 200 to 30 respectively. The activated carbon enhanced MBR system run steadily with low membrane fouling and con- stant flux under high MLSS of 15 g/L.
