摘要
无机陶瓷膜因抗污染性能好,机械强度高,耐酸、耐碱,再生性好等优势在含油废水处理方面备受关注.然而,陶瓷膜较高的生产成本和实际应用过程中的膜污染仍限制着其大规模工业化应用.采用低成本陶瓷材料和高效的膜制备技术设计低成本油水分离陶瓷膜可有效降低其生产成本,此外,膜污染控制与评价也是有效推动其工业化应用的重要环节,成为目前油水分离陶瓷膜的研究重点之一.本文从低成本膜材料、高效膜制备工艺及膜污染评价3个方面概述并总结了目前低成本油水分离陶瓷膜的研究进展,并对油水分离陶瓷膜未来的发展方向进行展望,为推动低成本高性能陶瓷膜技术在工业化含油废水处理中的应用提供参考.
With the advantages,including good anti-fouling performance,high mechanical strength and outstanding resistances to acid,alkali and regeneration,ceramic membranes have been attracted much attention in the treatment of oily wastewater.However,the high production cost of ceramic membrane and its fouling during practical application still limit their large-scale industrial application.The use of low-cost ceramic materials and efficient membrane preparation technology to design low-cost ceramic membranes for oil-water separation can effectively reduce the production cost.In addition,membrane fouling control and evaluation are also an important role to effectively promote its industrial application.This paper summarizes the current research progress of low-cost ceramic membranes for oil-water separation from three aspects:low-cost membrane materials,high-efficiency membrane preparation technology and membrane fouling evaluation,and forecasts the future development direction of oil-water separation ceramic membranes,provides reference for promoting the application of low-cost high-performance ceramic membrane technology in industrial oily wastewater treatment.
