超滤膜的制备方法及在临港含油污水中的应用
|
摘要
随着膜分离技术的应用领域不断扩大,对膜性能的要求也日益提高,特别是在提高膜的亲水性、抗污染性等方面。膜分离技术对临港含油污水的处理具有重要意义,本文通过对比L-S相转化法、小孔径PVDF超滤膜的制备方法和GO-PVDF的制备方法,探究不同制备超滤膜的方法对其膜纯水通量和截留率的影响,并对比了溶剂种类、PVDF浓度、无机盐浓度对超滤膜制备的影响。探究了将超滤膜技术应用于临港含油污水处理过程时,海水中盐含量对超滤膜的影响。
With the application of membrane separation technology is expanding,the requirements of membrane performance are also increasing,especially in improving the hydrophilic membrane,anti-pollution and other aspects. Membrane separation technology is of great significance to harbor treatment of oily wastewater,in this paper,by comparing the L-S phase conversion,the preparation method of small aperture PVDF ultrafiltration membrane and GO-preparation of PVDF,to explore the different methods of preparing ultrafiltration membrane on its membrane water flux and entrapment rate,and the comparison of the variety of solvent,concentration of PVDF,inorganic salt concentration on the influence of preparing ultrafiltration membrane. The effect of salt content in seawater on ultrafiltration membrane was studied when the ultrafiltration membrane technology was applied to the treatment of oily sewage in harbor.
