This review presented the performances of the pilot-scale anaerobic membrane bioreactors (AnMBRs) treating domestic wastewater. High COD removal efficiencies and low biosolids productions were achieved at HRTs comparable to conventional aerobic processes under ambient temperatures. The energy demands for fouling control in the pilot-scale AnMBRs ranged from 0.04 to 1.35kWh/m, which is lower than those of lab-scale AnMBRs and aerobic MBRs. The energy demands for fouling control were in the order of gas sparging>particle sparging>rotating membrane AnMBR. Two major factors affecting the energy demand in gas sparging AnMBRs were specific gas demands (SGD) and operating flux. The energy potentials in wastewater were significantly affected by the influent sulfate concentrations. Energy balances indicated that five out of nine pilot-scale AnMBRs was energy positive. However, further improvements of the AnMBRs are required to implement the energy positive wastewater treatment process.
本综述介绍了中试规模的厌氧膜生物反应器（AnMBR）处理生活污水的性能。在常温下，与传统好氧工艺相比，该反应器具有较高的 COD 去除效率和较低的生物固体产量。中试规模 AnMBR 中用于控制污染的能量需求范围为 0.04 至 1.35kWh/m，低于实验室规模 AnMBR 和好氧 MBR。用于控制污染的能量需求顺序为：气体喷射>颗粒喷射>旋转膜 AnMBR。影响气体喷射 AnMBR 中能量需求的两个主要因素是比需气量（SGD）和操作通量。废水中的能量潜力受进水硫酸盐浓度的显著影响。能量平衡表明，九个中试规模 AnMBR 中有五个是能量正的。然而，需要进一步改进 AnMBR，以实现能量正的污水处理过程。
