Abstract:

The radioactive uranium released in the process of uranium mining,processing and use poses a serious threat to the health of the surrounding residents and the ecological environment. Membrane technology has become an advanced technology for the harmless treatment of uranium-containing solutions due to its high efficiency,energy saving and strong adaptability. The status of membrane technology in treatment of uranium-containing wastewater from the nuclear industry,uranium-contaminated surface water and groundwater were reviewed. The research development of ultrafiltration,nanofiltration,reverse osmosis,liquid membrane,membrane distillation and electrodialysis in the treatment of uranium-containing solutions were mainly summarized. By introducing the basic principles of various membrane processes,analyzing the influence of operating conditions and membrane properties on uranium removal efficiency,the advantages and limitations of these membrane processes in treatment of uranium-containing solutions were discussed. In general,membrane technology could effectively remove uranium from wastewater with good retention. Some membrane processes had certain selectivity for uranium,which was beneficial to recover uranium from high-salinity wastewater.

Key words: membrane separation, uranium-containing wastewater, pressure driven membrane

摘要:

铀矿开采、加工和使用过程中释放出的放射性铀对周边居民健康及生态环境已造成严重威胁。膜技术因其高效节能、适应性强,已成为含铀溶液无害化处理的先进技术。概述了膜技术在核工业含铀废水、受污染的含铀地表水及地下水处理中的研究现状,主要归纳了超滤、纳滤、反渗透、液膜、膜蒸馏及电渗析等膜过程处理含铀溶液的研究进展。通过介绍各类膜处理过程的基本原理、分析其操作条件及膜结构性能对铀去除效果的影响,指出了各类膜过程在含铀溶液处理中所具有的优势和存在的问题。总体而言,膜过程对铀具有较好的截留性,能有效去除废水中的铀,部分膜过程具有一定的离子选择性,有利于从高盐度废水中回收铀。
