膜过滤技术对油田污水处理的研究

Research on the treatment of oilfield wastewater by membrane filtration technology

膜过滤技术越来越受到各行各业的重视,已形成了过滤与分离行业的企业联合化,广泛用于各行业对固体、液体、气体单相或多相混合物的分级、分离和纯化。根据要求的不同,膜过滤技术逐渐形成了以微滤(MF)、纳滤(NF)、超滤(UF)和反渗透(RO)等各种膜和组器件等,另外还有渗析、离子交换膜分离系列等系统。

Membrane filtration technology is gaining more and more attention from all walks of life,and has formed a joint enterprise in the filtration and separation industry,which is widely used in various industries for the classification,separation and purification of solid,liquid,gas single-phase or multi-phase mixtures.According to different requirements,membrane filtration technology has gradually formed various membranes and components such as microfiltration(MF),nanofiltration(NF),ultrafiltration(UF)and reverse osmosis(RO),in addition to dialysis,ion Exchange membrane separation series and other systems.
