- Abstract:
- Hydrogen-based membrane biofilm reactor (H2-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 H2-MBfR still face challenges, particularly in terms of pH control. The article primarily provides an introduction to the working principle and characteristics of H2-MBfR. It also delves into the impact of pH on the reactor’s performance in the removal of oxidative pollutants from H2-MBfR. Furthermore, it discusses various pH control methods employed in H2-MBfR and analyzes their effects on the microbial community. Eventually, suggestions are put forward for the deficiencies of pH control research in H2-MBfR at this stage.
