| 摘 要： | 用阳离子型聚丙烯酰（PAM）和聚合铝（PAC）作混凝剂进行了纤维束直接过滤实验，对纤维束上积泥进行了扫描电镜照像及图象分析，得出了积泥孔隙周界曲线的分维数，探讨了分维数与过滤过程的关系，指出了在直接过滤中阳离子型PAM较PAC效果好的原因所在。

| Abstract: | Direct filtration with fiber bundle as filter media was studied experimentally with cationic polyacrylamide and polyalumchloride as coagulant The fractal dimensions of deposition porosity boundary curve were obtained by photographing deposition surface on fiber bundle with scanning electron microscope and image analysis with image analyser The relationships between fractal dimension and filtration process are discussed It is pointed out that the effect of cationic polyacrylamide is preferable to polyalumchloride in direct fitration |

| Keywords: | direct filtration deposition structure coagulant fractal dimension |
