摘要
将分形和分数维概念用于水处理多孔填料表面特征和微孔结构的研究,并通过对酶促生物填料测试数据的分析证明:多孔填料的表面和微孔结构具有典型的分形特征,其面积分数维越大,填料表面越粗糙;其容积分数维越大,微孔占有空间的能力越强。因此,该方法为多孔填料的开发研究和性能分析提供了一种新思路和新方法。
Fractal and fractal dimensions are introduced into the research on the surface character and micropore structure of porous media used in water and wastewater treatment.By the analysis of the test data of enzyme -promoting biological media,it has been proved that the surface and micropore structure are of typical fractal nature.The larger the fractal dimensions of area become,the rougher the surface of the media is ,and the larger the fractal dimensions of volume become,the stronger the ability of the space expansion of micropore is .Therefore,it provides a new thinking and a new method for research,development and performance analysis of porous media.
