A modified anaerobic baffled reactor (ABR) combined with a submerged membrane bioreactor (MBR) was applied to treat municipal wastewater. The performance of this process was examined in terms of the removal of organic matter, suspended solids, turbidity and nitrogen. The raw wastewater was fed to the 105 L ABR and then the treated effluent was driven to a 58 L MBR equipped with a submerged hollow fibre ultrafiltration membrane module. The integrated modified ABR-MBR process resulted in the complete removal of total suspended solids (TSS) and in very high chemical oxygen demand (COD) removal (93.3 ± 3.8%). Furthermore, the recycling of mixed liquor from the MBR to the modified ABR resulted in some denitrification occurring in the first compartment of the ABR, resulting in 53 ± 6% removal of nitrogen by the integrated process. The membrane flux was stable and above 20 L/mh. Membrane examination at the nanoscale indicated the deposition of small particles on the surface of the membranes.
采用改良型厌氧折流板反应器（ABR）与浸没式膜生物反应器（MBR）相结合的工艺处理城市污水。从有机物、悬浮固体、浊度和氮的去除方面考察了该工艺的性能。原污水进入105升的ABR，然后将处理后的出水引入一个装有浸没式中空纤维超滤膜组件的58升MBR。改良型ABR-MBR一体化工艺实现了总悬浮固体（TSS）的完全去除以及很高的化学需氧量（COD）去除率（93.3±3.8%）。此外，将MBR的混合液回流至改良型ABR，使得ABR第一隔室发生了一定程度的反硝化作用，该一体化工艺的总氮去除率达到53±6%。膜通量稳定且高于20升/（平方米·小时）。纳米级别的膜检测表明，膜表面有小颗粒沉积。
