摘　　要：膜污染问题限制了膜分离技术在实际工程中的广泛应用。从分形解析的角度深入探讨混凝-膜过滤过程中滤饼层的微观结构对控制膜污染情况至关重要。总结和回顾了运用分形理论表征滤饼层重要性质参数孔隙率、比阻、渗透率研究的前沿动态,对絮体特性和滤饼层特性两者内在关系进行分析评述,以期为混凝-膜过滤工艺优化提供参考。Membrane fouling limits the wide application of membrane separation technology in practical engineering.It is of great significance to discuss the microstructure of cake layer in the process of coagulation membrane filtration for controlling membrane fouling from the perspective of fractal.The foreword dynamics of the research on the characterization of the important property parameters of filter cake layer were summarized and reviewed by fractal theory,such as porosity,specific resistance and permeability.The internal relationship between the floc property and the filter cake layer property was also analyzed and commented,in order to provide reference for the optimization of coagulation-membrane filtration process.
