离子型稀土为我国特有的战略性资源，其冶炼过程会产生大量废水，经现有技术处理后排放水中仍含有稀土离子。因此开展稀土废水处理新技术及稀土资源化回收的研究具有十分重要意义。在深入研究膜的“制备条件-表面微结构-分离性能”三者关系的基础上，通过共价交联剂、膜表面修饰手段对膜的d-spacing和微结构的精准调控，利用LBL自组装出高水通量的氧化石墨烯框架（GOF）复合膜。系统考察GOF膜的制备条件、膜操作条件（温度、压力、pH、稀土离子浓度、盐浓度、膜操作方式等）对GOF膜分离/浓缩富集稀土离子性能的影响；结合有效的表征手段和传质数学模型，研究稀土离子在复合膜表界面上的作用机制；探究高盐稀土废水处理过程中水和稀土离子在膜层的传质机理，提高膜的分离性能、稳定性能和制备重复性，为我国新型膜分离材料在稀土工业废水的绿色高效处理及资源化综合利用中提供重要科学依据。

Ionic-type rare earth (RE) ore is the specific strategic resources in China, while it produces a large amount of wastewater during smelting processes. However, there are still containing RE ions in the exhausted water after treated with traditional separation technology. Therefore, it is of great significance to develop new technology for RE wastewater treatment and RE ions resource recycling for comprehensive utilization. In this project, the relationship among the membrane preparation conditions, membrane surface microstructure and their separation performance will be investigated in details. The high-flux water-permeable graphene oxide framework (GOF) composite membranes with high RE ions rejection and stability are prepared by the lay-by-lay (LBL) self-assembly technology with precise tunable d-spacing for GOF materials and membrane surface microstructure, which are regulated by covalent cross-linkers and surface modification methods. The influence of membrane preparation conditions and different experimental conditions such as temperature, pressure, pH, RE ion concentration, salt concentration, ionic strength, membrane operation modes, etc. on the membrane separation performance or enrichment of RE ions in wastewater are discussed. Moreover, with the aid of mathematical simulation combined with the experimental data and effective characterization methods, the interaction between RE ions and GOF membranes interface, and mass transfer mechanism of water and RE ions through the membrane layers are studied in high-salt RE wastewater systems. It will be to improve the separation performance, stability and preparation of repeatability for the GOF membranes. It will be to provide scientific support for the development of new membrane materials for application in the RE wastewater treatment, recycling resource and comprehensive utilization in China.
