A pilot-scale integrated membrane-aerated biofilm reactor (MABR) system, consisted of hydrolysis/acidification pretreatment, MABR process and activated carbon adsorption post-processing, was designed to treat the high-loading mixed pharmaceutical wastewater. A study of MABR process was conducted to investigate the effect of aeration condition, circulation flow rate and water quality on performance over 260 days. The performances of these processes were evaluated by the removal efficiency of COD, BOD(5), turbidity, NH(4)(+)-N and TN. MABR process could effectively remove above 90% of COD and 98% of ammonia. The capacities per unit volume of MABR could reach up to 1311 gCOD/m(3)d and 48.2 gNH(4)(+)-N/m(3)d with single membrane aeration, and the oxygen utilization rate could be as high as 45%. After post-processing, the effluent of integrated treatment MABR system kept stable with COD below 200 mg/L and NH(4)(+)-N below 3 mg/L.
采用水解/酸化预处理、膜曝气生物膜反应器（MABR）工艺和活性炭吸附后处理的中试规模集成膜曝气生物膜反应器（MABR）系统，被设计用来处理高负荷混合制药废水。通过对 MABR 工艺进行研究，考察了曝气条件、循环流量和水质对 260 天运行性能的影响。通过 COD、BOD(5)、浊度、NH(4)(+)-N 和 TN 的去除效率来评估这些工艺的性能。MABR 工艺可有效去除超过 90%的 COD 和 98%的氨。在单膜曝气条件下，MABR 的单位体积处理能力可高达 1311 gCOD/m(3)d 和 48.2 gNH(4)(+)-N/m(3)d，氧气利用率高达 45%。经过后处理，集成处理 MABR 系统的出水 COD 保持稳定在 200mg/L 以下，NH(4)(+)-N 保持在 3mg/L 以下。
