Traditional wastewater treatment technologies have become increasingly inefficient to meet the needs of low-consumption and sustainable wastewater treatment. Researchers are committed to seeking new wastewater treatment technologies, to reduce the pressure on the environment caused by resource shortages. Recently, a microalgal-bacterial granular sludge (MBGS) technology has attracted widespread attention due to its high efficiency wastewater treatment capacity, low energy consumption, low CO emissions, potentially high added values, and resource recovery capabilities. This review focused primarily on the following aspects of microalgal-bacterial granular sludge technology: (1) MBGS culture and maintenance operating parameters, (2) MBGS application in different wastewaters, (3) MBGS additional products: biofuels and bioproducts, (4) MBGS energy saving and consumption reduction: greenhouse gas emission reduction, and (5) challenges and prospects. The information in this review will help us better understand the current progress and future direction of the MBGS technology development. It is expected that this review will provide a sound theoretical basis for the practical applications of a MBGS technology in environmentally sustainable wastewater treatment, resource recovery, and system optimization.
传统的废水处理技术已变得越来越低效，难以满足低消耗和可持续废水处理的需求。研究人员致力于寻求新的废水处理技术，以减轻资源短缺对环境造成的压力。最近，由于其高效的废水处理能力、低能耗、低 CO 排放、潜在的高附加值和资源回收能力，微藻-细菌颗粒污泥（MBGS）技术引起了广泛关注。本综述主要集中在微藻-细菌颗粒污泥技术的以下几个方面：（1）MBGS 培养和维护的操作参数，（2）MBGS 在不同废水中的应用，（3）MBGS 的附加产品：生物燃料和生物制品，（4）MBGS 节能降耗：减少温室气体排放，（5）挑战与展望。本综述中的信息将有助于我们更好地了解 MBGS 技术的当前进展和未来方向。预计本综述将为 MBGS 技术在环境可持续的废水处理、资源回收和系统优化中的实际应用提供坚实的理论基础。
