过滤是一种常用的含油废水深度处理方法，在过滤单元操作中，滤料的品种对处理效果有重要影响，其中滤料的润湿性是最重要的影响因素之一。本论文以Washburn方程为原理，用动态渗透压力法研究了无烟煤、活化沸石、铝矾土陶瓷、磁铁矿及沸石5中滤料的亲油亲水润湿性，当滤料粒径范围分别在20～30目和30～40目之间时，实验结果较为准确可靠。结果表明粒径范围在20～30目时，用动态渗透压力法测得的无烟煤、活化沸石、铝矾土陶瓷、磁铁矿及沸石滤料的LHR值依次为2．21、1．77、1．75、1．32和1．26；粒径范围在30～40目时，用动态渗透压力法测得的活化沸石、铝矾土陶瓷及磁铁矿滤料的LHR值依次为2．28、2．27和0．86。

Filtration is a typical tertiary treatment method for oil-bearing water, The kinds of filter media and its surface nature have an important influence on treatment result in the filtration unit operation. The wettability of filter media is the most important influence factor. The lipophilic and hydrophilic properties of anthracite, activated zeolite, bauxite ceramic, magnetite and zeolite were studied by using dynamic osmotic Pressure method, which is based on the principle of Washburn equation. When filter media size distribution are 20~ 30 meshes and 30 40 meshes, using dynamic osmotic pressure method to study wettability of the filter media is feasible and the experiment results is precise and credible. When the particle size distribution are between 20meshes and 30 meshes, the LHR values of anthracite, activated zeolite, bauxite ceramic, magnetite and zeolite are 2.51,1.77,1.75,1.32 and 1.26 respectively, when the particle size distribution are between 30meshes and 40 meshes, the LHR values of activated zeolite, bauxite ceramic and magnetite are 2.28,2.27 and 0.86 respectively.
