中文摘要：

采用原子力显微镜液池成像技术对微絮凝过滤工艺过程中的微絮凝时间和搅拌强度进行优化.结果表明,原子力显微镜液池成像技术可以对混凝过程中的微絮体进行形貌表征和数字描述,并证实微絮凝过滤工艺在处理实际印染工业尾水过程中,微絮凝时间为2 min,搅拌强度为100 s-1时可以达到优化的处理效果.

英文摘要：

Atomic force microscope（AFM） fluid imaging was applied to the study of micro-flocculation filtration process and the optimization of micro-flocculation time and the agitation intensity of G values.It can be concluded that AFM fluid imaging proves to be a promising tool in the observation and characterization of floc morphology and the dynamic coagulation processes under aqueous environmental conditions.Through the use of AFM fluid imaging technique,optimized conditions for micro-flocculation time of 2 min and the agitation intensity（G value） of 100 s-1 were obtained in the treatment of dye-printing industrial tailing wastewater by the micro-flocculation filtration process with a good performance.
