摘　　要：含油废水是一种常见的工业废水,而过滤法则是常见的一种水深度处理方法,本文基于Washburn方程,采用动态渗透压力法测定了无烟煤、活化沸石、锰砂、石英砂、磁铁矿的亲油亲水比(LHR),并采用含油浓度为15mg/L的废水,以这五种常见滤料做了动态过滤实验,分别测定了5h内的油去除率,结果表明,随着亲油亲水比的增加,去除效率呈增加趋势,且亲油亲水比和去除效率有一定的相关性。The lipophilic and hydroPhilic properties of anthraeite, aetivated zeolite, manganese sand, quartz sandand magnetite were studied by using dynamic osmotic Pressure method,which is based on the principle of Washburn Equation. 15mg/l oil concentration by using the wastewater,to which five common filter media to do a dynamic experiments were determined within 5 hours of oil removal. The results show that lipophilic hydrophilic ratio and removal efficiency of oil has some relevance.
