摘　　要：考虑到超亲水材料具有优良的亲水疏油性能,有望应用于溢油处置领域,在原油环境下开展不同流道、不同孔径的不锈钢网和超亲水材料的分离测试实验,结果表明,超亲水材料的分离性能明显优于不锈钢网,在单级分离情况下,经超亲水材料分离后出水口的含油量均降低至50 mg/L以下,出油口的含油量则保持在85%以上。对于优化流道后的双级分离,不同孔径超亲水材料的分离效率均在99.9%以上,分离后溢油回收物的浓缩倍数处于12~19之间,当第二级超亲水材料孔径为9μm时,出水口含油量降低至15 mg/L以下。Super hydrophilic materials are expected to be applied in the field of oil spill disposal due to their excellent hydrophilic and oil repellent properties.In order to provide a reference for the application of super hydrophilic materials in oil spill response,the crude oil recovery and separation experiments were carried out using stainless steel mesh and super hydrophilic materials with different flow channels and pore sizes.It was found that the separation property of super-hydrophilic material is obviously better than that of stainless steel mesh.In the case of single-stage separation,the oil content in the outlet is reduced to less than 50 mg/L,and the oil content in the oil outlet is maintained above 85%.For the optimized-two-stage separation,the separation efficiency of all the hydrophilic materials is more than 99.9%,and the concentration multiple of the oil spill recovery is between 12~19.The oil content at the outlet can be reduced to less than 15 mg/L when the hydrophilic material with 9μm mesh used in second stage.
