Membrane bioreactors (MBRs) have been utilized for maricultural wastewater treatment, where high-salinity stress results in dramatic membrane fouling in the actual process. A microalgal-bacterial symbiotic system (MBSS) offers advantages for photosynthetic oxygen production, dynamically regulating the structure of extracellular polymeric substances (EPSs) and improving the salinity tolerance of bacteria and algae. This study centered on the mechanisms of membrane fouling mitigation via the microalgal-bacterial interactions in the MBSS, including improving the pollutant removal, optimizing the system parameters, and controlling the gel layer formation. Moreover, the contribution of electrochemistry to decreasing the inhibitory effects of high-salinity stress was investigated in the MBSS. Furthermore, patterns of shifts in microbial communities and the impacts have been explored using metagenomic technology. Finally, this review aims to offer new insights for membrane fouling mitigation in actual maricultural wastewater treatment.
膜生物反应器（MBR）已被用于海水养殖废水处理，在实际过程中，高盐度胁迫会导致严重的膜污染。微藻-细菌共生系统（MBSS）在光合产氧、动态调节胞外聚合物（EPS）结构以及提高细菌和藻类的耐盐性方面具有优势。本研究聚焦于MBSS中微藻-细菌相互作用减轻膜污染的机制，包括提高污染物去除率、优化系统参数以及控制凝胶层形成。此外，还研究了MBSS中电化学对降低高盐度胁迫抑制作用的贡献。此外，利用宏基因组技术探索了微生物群落的变化模式及其影响。最后，本综述旨在为实际海水养殖废水处理中的膜污染减轻提供新的见解。
