摘　　要：重力驱动膜滤技术(GDM)因其运行成本低、出水水质高、通量稳定、无需反洗等优点,在水处理领域尤其是分散型饮用水的安全保障方面展现出显著优势。但GDM稳定通量略低、对部分污染物去除能力有限等缺点限制了其推广应用。基于重力驱动膜滤技术净水效能优化提升的研究和应用需求,从GDM技术的稳定通量、污染物去除效能、膜污染控制及膜清洗等角度出发,综述GDM效能调控策略的研究进展。讨论了进水水质改善、生物滤饼层结构调控、操作参数优化、膜组件配置、膜材料改性及联用技术在提高GDM净水效能方面的作用,阐述了膜污染控制方法和膜清洗策略,并对围绕GDM技术的科研和实践方向进行展望,可为扩大GDM的使用范围,加速推进GDM技术在水厂等实际工程中的实践应用提供支撑。Gravity-driven membrane filtration(GDM)technology has shown significant advantages in the field of water treatment,especially in the safety assurance of dispersed drinking water,due to its low operating cost,high effluent quality,stable flux,and no need for backwashing.However,the disadvantages of GDM,such as lower stable flux and limited removal capacity for some contaminants,limit its popularization and application.Based on the research and application requirements for the optimization and improvement of water purification efficiency of GDM,this paper summarizes the research progress in strategies for regulating GDM efficiency from the perspectives of stable flux,contaminant removal efficiency,membrane pollution control,and membrane cleaning.This paper discusses the improvement of influent water quality,structural control of the bio-cake layer,optimization of operating parameters,configuration of membrane components,modification of membrane materials,and the role of combined technologies in improving the water purification efficiency of GDM.It also expounds membrane pollution control methods and membrane cleaning strategies,and looks into the future research and practical directions around GDM technology to provide support in expanding the scope of use of GDM,and accelerating the application of GDM technology in practical projects including water plants.
