Abstract

In recent years, the environmental unsustainability of traditional wastewater treatment processes, alongside the growing emphasis on carbon neutrality and self-sufficiency in wastewater treatment plants (WWTPs), has drawn attention to algal-bacterial aerobic granular sludge (AGS) systems. This review synthesizes recent advances in algal-bacterial AGS, focusing on the latest research on its granulation mechanisms under both hydrostatic and hydrodynamic conditions and providing a comprehensive overview of cultivation strategies based on various sludges. We discuss the latest reports on the impacts of process operation strategies for algal-bacterial AGS and emphasize the operation performance and design of different bioreactor configurations. Challenges for commercialization and sustainable applications are highlighted; future application directions are also posted. In summary, algal-bacterial AGS exhibits significant potential in simultaneous efficient wastewater treatment and bioresource recovery, targeting circular bioeconomy and sustainable wastewater industry.

藻-细菌好氧颗粒污泥的研究进展：从接种方法到操作策略

近年来，传统废水处理工艺的环境不可持续性，以及对污水处理厂（WWTPs）碳中和和自给自足的日益重视，引起了人们对藻类-细菌好氧颗粒污泥（AGS）系统的关注。本文综述了近年来藻-细菌AGS的研究进展，重点介绍了藻-细菌AGS在流体静力和流体动力条件下造粒机理的最新研究进展，并对基于各种污泥的培养策略进行了综述。我们讨论了对藻-细菌AGS工艺操作策略影响的最新报道，并强调了不同生物反应器配置的运行性能和设计。强调了商业化和可持续应用方面的挑战；未来的应用方向也已公布。综上所述，藻-细菌AGS在同时高效处理废水和生物资源回收方面具有巨大的潜力，可用于循环生物经济和可持续废水工业。
