摘要:

薄層復合納濾膜因具有成本低、分離效果良好等特點被廣泛關注，現如今對于復合納濾膜的研究主要側重于對其性能的改性及優化，如表面接枝、構建中間層、共混基質等。但由于在復雜的水處理環境中復合納濾膜應用效果并不理想，因此在制備復合納濾膜時，不僅要提高其膜通量和截留率，還應注重其機械強度、抗腐蝕性能以及抗污染能力的優化和改進。分別從基膜優化、中間層構建以及分離層優化3個角度來總結分析近些年國內外專家學者對復合納濾膜的研究成果，從而為復合納濾膜在實際工程中的應用提供一些參考。

Abstract:

With the advantages of low cost and good separation effect, the thin-film composite nanofiltration membranes are widely concerned. Nowadays, the research on composite nanofiltration membrane mainly focuses on the modification and optimization of its performance, such as surface grafting, construction of intermediate layer, blending matrix and so on. However, due to the complex water treatment environment, the effect of composite nanofiltration membrane in practical application is not ideal. Therefore, when preparing composite nanofiltration membrane, not only the membrane flux and rejection rate should be improved, but also the optimization and improvement of its mechanical strength, corrosion resistance and anti-pollution ability should be paid to attention. Hence, this paper summarizes and analyzes the research results of composite nanofiltration membrane by experts and scholars at home and abroad in recent years from three aspects: optimization of basal membrane, construction of intermediate layer and optimization of separation layer, which may provide certain reference for the application of composite nanofiltration membrane in practical engineering.
