摘 要
聚合物膜分离技术作为一种高效、环保的废水处理方法,近年来在工业和市政废水处理领域得到了广泛关注。随着工业化进程的加快,废水排放量不断增加,传统处理方法已难以满足日益严格的环保要求。因此,开发新型高效的废水处理技术显得尤为重要。本研究旨在探讨聚合物膜分离技术在废水处理中的应用效果及其机理,通过实验研究和理论分析相结合的方法,系统评估了不同类型聚合物膜对多种污染物(如重金属离子、有机物和微生物)的去除效率。研究结果表明,聚合物膜具有优异的选择性和高通量特性,能够有效去除废水中的有害物质,显著提高水质。特别是在处理含有复杂污染物的工业废水时,聚合物膜表现出良好的稳定性和耐久性。此外,本研究还发现,通过优化膜材料和操作条件,可以进一步提高膜的分离性能和使用寿命。这些发现为聚合物膜在实际废水处理工程中的应用提供了科学依据和技术支持。本研究的另一创新点在于引入了多尺度模拟技术,从分子层面揭示了污染物与膜材料之间的相互作用机制,为膜材料的改性和优化设计提供了理论指导。

Abstract
As an efficient and environmentally friendly wastewater treatment method, polymer membrane separation technology has gained extensive attention in the field of industrial and municipal wastewater treatment recently. With the acceleration of industrialization and the increasing discharge of wastewater, the traditional treatment methods have been difficult to meet the increasingly strict environmental protection requirements. Therefore, it is particularly important to develop a new and highly efficient wastewater treatment technology. The purpose of this study is to explore the application effect and mechanism of polymer membrane separation technology in wastewater treatment. Through the combination of experimental research and theoretical analysis, the removal efficiency of different types of polymer membrane for many pollutants (e. g., heavy me tal ions, organic matter and microorganisms) is systematically evaluated. The results show that the polymer membrane has excellent selectivity and high-throughput characteristics, which can effectively remove harmful substances in wastewater and significantly improve the water quality. In particular, the polymer films showed good stability and durability when treating industrial wastewater containing complex pollutants. Furthermore, this study found that the separation performance and lifetime of the membrane could be further improved by optimizing the membrane material and operating conditions. These findings provide the scientific basis and technical support for the application of polymer membrane in practical wastewater treatment engineering. Another innovation of this study is the introduction of multi-scale simulation technology, which reveals the interaction mechanism between pollutants and membrane materials from the molecular level, and provides theoretical guidance for the modification and optimization design of membrane materials.
