摘　　要：氢基质膜生物膜反应器(Hydrogen-based membrane biofilm reactor,H_(2)-MBfR)是一种将膜技术与生物膜结合,利用氢气作为无机电子供体将氧化性污染物高效还原去除的新型氢自养反应器。该反应器除了具有一般生物膜反应器的特点外,还具有高效、洁净、低成本等优点,近些年备受学者关注。然而,目前H_(2)-MBfR的进一步开发和规模化应用仍面临着挑战,这其中就包括pH控制。主要介绍了H_(2)-MBfR工作原理与特性,并阐述了pH在H_(2)-MBfR去除氧化性污染物过程中对反应器性能的影响,进而论述了H_(2)-MBfR中不同的pH控制方法且分析了pH控制对微生物群落的影响。最后针对现阶段H_(2)-MBfR中pH控制研究的不足提出建议。Hydrogen-based membrane biofilm reactor (H_(2)-MBfR) is a novel hydrogen autotrophic reaction that integrates membrane technology with biofilm.It utilizes hydrogen as inorganic electron donor to efficiently reduce and remove oxidative pollutants.In addition to the typical advantages of general biofilm reactors,this reactor also offers high efficiency,cleanliness,and low cost.These features have garnered significant attention from scholars in recent years.However,the further development and large-scale application of H_(2)-MBfR still face challenges,particularly in terms of pH control.The article primarily provides an introduction to the working principle and characteristics of H_(2)-MBfR.It also delves into the impact of pH on the reactor’s performance in the removal of oxidative pollutants from H_(2)-MBfR.Furthermore,it discusses various pH control methods employed in H_(2)-MBfR and analyzes their effects on the microbial community.Eventually,suggestions are put forward for the deficiencies of pH control research in H_(2)-MBfR at this stage.
