生物质基油水分离膜的应用现状及前景展望

Application Status and Prospect of Biomass-based Oil-water Separation Membrane

随着当前全球石化行业的快速发展,水资源的短缺和工业废水排放的增长已经极大地阻碍了社会和环境的可持续性发展。含油废水是其中占比最大也是比较难处理的一种废水,膜分离法是目前处理含油废水的有效方法之一。而目前市场上主流的油水分离膜部分或全部使用了不可再生和非降解性原料,会对环境造成二次污染。以生物质材料为主要原材料的生物质基油水分离膜以其绿色、可持续、高效、可降解等优势得到了极大地关注。本文从生物质基油水分离膜的生物质来源、种类、相应的制备及改性方法、应用研究现状及主要问题进行论述,对未来生物质基油水分离膜的前景进行展望。

With the rapid development of the global petrochemical industry,the shortages of water resources and the growth of industrial wastewater have greatly hindered the sustainable development of the society and environment.Oily wastewater is one of the largest proportions and also one of the most difficult types to treat.Membrane separation is currently one of the most effective methods for treating oily wastewater.At present,some or all of the mainstream oil and water separation membranes in the market use nonrenewable and non-degradable raw materials,causing secondary pollution to the environment.Biomassbased oil-water separation membrane with biomass material as the main raw material has attracted great attention for its green,sustainable,efficient and degradable advantages.In this paper,the sources and types of biomass,the corresponding preparation and modification methods,the status of application research and the main problems of biomass based oil-water separation membrane were discussed,and the development of biomass based oil-water separation membrane in the future is prospected.
