通过对纤维束滤料积泥表面进行电镜照像及图像分析 ,得到了不同条件下积泥孔隙结构的分维数 ,并探讨了积泥孔隙结构分维数与过滤过程及直接过滤中混凝剂效果的关系 .结果表明 ,分维数可用于研究积泥结构及其对过滤过程的影响 ,且可用于评价直接过滤中混凝剂的效果 .
The fractal dimension of the pore structure under different conditions was obtained by electron microscopy and image analysis of the surface of the fiber bundle filter sediment. The fractal dimension of the pore structure and the filtration process and the direct filtration coagulation The results show that the fractal dimension can be used to study the sediment structure and its influence on the filtration process, and can be used to evaluate the effect of coagulant in direct filtration.
