陶瓷微滤膜改性技术及其含油废水处理应用

摘要

当前含油废水对环境的污染非常严重，而膜法处理含油废水仍然存在诸如渗透通量较低、渗透液中油含量较大等缺陷。因此，迫切需要通过技术手段解决上述问题。而研发低成本高性能的基膜材料和采用膜改性技术提升膜性能，目前已成为解决上述问题的重要手段。由此，本文提出了采用纳米金属氧化物和氧化石墨烯对商业化陶瓷微滤膜进行改性，并将其应用于油水分离，实现膜油水分离效率显著提升。%Currently, oily wastewater pollution of the environment is very serious, and membrane treatment of oily wastewater is still in use, but with little permeate lfux, large permeate oil content and other defects. Therefore, technical methods are urgently needed to solve the above defects. The development of low-cost and high-performance support materials and the use of modiifcation to enhance membrane performance have become important solutions to these problems. Thus, we propose the use of nano metal oxides and graphene oxide in the modiifcation of the commercial ceramic microifltration membrane and the treatment of the oily wastewater, and the membrane with superior oil-water separation efifciency can be achieved.
