摘 要
膜分离技术作为现代水处理领域的核心技术之一，因其高效、节能和环保的特点而受到广泛关注。然而，当前膜分离技术在实际应用中仍面临诸多瓶颈问题，如膜污染、选择性与渗透性之间的权衡以及材料耐久性不足等，这些问题严重制约了其进一步推广和优化。采用功能化改性、纳米复合材料引入以及智能响应膜的设计，能够显著提升膜的抗污染性能和分离效率；结合过程强化技术（如电场辅助或超声波处理）可进一步改善膜的长期稳定性。本研究还提出了基于大数据和人工智能的膜性能预测模型，为膜分离技术的个性化设计和精准调控提供了新思路。本研究不仅揭示了现有技术的局限性，还明确了未来发展方向，为推动膜分离技术在水处理领域的广泛应用奠定了理论和技术基础。

Abstract
Membrane separation technology, as one of the core technologies in the field of modern water treatment, has been widely concerned because of its characteristics of high efficiency, energy saving and environmental protection. However, the current membrane separation technology still faces many bottleneck problems in practical application, such as membrane pollution, the trade-off between selectivity and permeability, and the lack of material durability, which seriously restricts its further promotion and optimization. Using functional modification, the introduction of nano-composite materials and the design of intelligent responsive membrane can significantly improve the anti-pollution performance and separation efficiency of the membrane. Combined with process strengthening techniques, such as electric field assistance or ultrasonic treatment, the long-term stability of the membrane can be further improved. This study also proposes a membrane performance prediction model based on big data and artificial intelligence, which provides a new idea for the personalized design and precise regulation of membrane separation technology. This study not only reveals the limitations of the existing technology, but also clarifies the future development direction, and lays a theoretical and technical foundation for promoting the wide application of membrane separation technology in the field of water treatment.
