Summary:The invention discloses an oil-water separation modified filter material and a preparation method thereof, polyvinyl alcohol, agarose powder, polyethylene glycol and tannic acid are used for preparing a modified solution, and the filter material is soaked and modified to obtain the oil-water separation modified filter material. The modified filter material disclosed by the invention has super-hydrophilic and super-oleophobic properties in water, so that the modified filter material has excellent self-cleaning performance of oil adhesion resistance, and meanwhile, treated wastewater can reach the discharge standard. 本发明公开了一种油水分离改性滤料及其制备方法,本发明是利用聚乙烯醇、琼脂糖粉末、聚乙二醇、单宁酸制成一种改性溶液,并对滤料进行浸泡改性处理,从而获得一种油水分离改性滤料。本发明的改性滤料具有超亲水-水中超疏油性质,从而具有优异的抗油粘附的自清洁性能,同时处理后的废水能够达到排放的标准。
