摘　　要：将膜蒸馏技术应用到高盐污水处理回用领域,以石化反渗透浓水为实验体系,采用几种现有的疏水膜材料,研究了不同类型的各种材质的膜对膜蒸馏过程通量及产水水质的影响。在此基础上,采用酸碱清洗液对膜蒸馏的膜污染进行了清洗,并进行了清洗效果的表征。Membrane distillation is used for the treatment and reuse of wastewater with high salinity. In this study, the petrochemical RO concentrated wastewater is used as research system. The effects of types of membranes on the flux of membrane distillation and the quality of the produced water are investigated. Furthermore, membrane pollution is cleaned by using various cleaning solution. The cleaning effect is evaluated as well.
