Aiming at deepening the understanding of the formation and evolution of emerging microalgal-bacterial granule (MBG)-based wastewater treatment systems, the recent advances regarding the formation processes, transfer phenomena, innovative bioreactors development and wastewater treatment performance of MBG-based systems are comprehensively reviewed in this work. Particularly, the successful establishments of MBG-based systems with various inocula are summarized. Besides, as the indispensable factors for biochemical reactions in MBGs, the light and substrates (organic matters, inorganic nutrients, etc) need to undergo complicated and multi-scale transfer processes before being assimilated by microorganisms within MBGs. Therefore, the involved transfer phenomena and mechanisms in MBG-based bioreactors are critically discussed. Subsequently, some recent advances of MBG-based bioreactors, the application of MBG-based systems in treating various synthetic and real wastewater, and the future development directions are discussed. In short, this review helps in promoting the development of MBG-based systems by presenting current research status and future perspectives.
针对深化新兴微藻-细菌颗粒（MBG）基废水处理系统的形成和演变的理解，本工作全面回顾了 MBG 基系统的形成过程、传质现象、创新生物反应器开发和废水处理性能方面的最新进展。特别是，总结了使用各种接种物成功建立 MBG 基系统的情况。此外，作为 MBG 内生化反应不可缺少的因素，光和底物（有机物质、无机养分等）需要在被 MBG 内微生物同化之前经历复杂的多尺度传质过程。因此，文中批判性地讨论了 MBG 基生物反应器中的传质现象和机制。随后，讨论了 MBG 基生物反应器的一些最新进展、MBG 基系统在处理各种合成和实际废水方面的应用以及未来的发展方向。总之，本综述通过呈现当前的研究现状和未来展望，有助于推动 MBG 基系统的发展。
