摘要
在当前水资源紧缺与水质安全双重挑战下,双膜法技术以其优异的分离效能成为水处理领域的重要解决方案。双膜法基于物理截留与选择性分离机制,能够达到高效去除悬浮物(大于98%),99%以上脱盐率及重金属去除率,实现水质的深度净化。通过不同膜组合工艺的协同作用,介绍了双膜法的技术原理、行业应用现状以及发展趋势。基于膜材料性能优化与系统集成、能量回收和循环利用以及零排放工艺的深度融合,双膜法技术加速向低碳节能、资源循环方向演进,为构建可持续水循环体系提供关键技术支撑。
Under the dual challenges of global water scarcity and deteriorating water quality safety,dual-membrane technology has emerged as a pivotal solution in water treatment due to its exceptional separation efficiency.By leveraging the synergistic mechanisms of physical sieving and selective separation,this technology achieves advanced water purification with suspended solids removal exceeding 98%,desalination rates surpassing 99%,and heavy metal rejection rates over 99%.This paper elucidates the technological principles,current industrial applications,and developmental trajectories of dual-membrane systems through the analysis of synergistic interactions in hybrid membrane configurations.The synergistic integration of membrane material optimization,system engineering innovation,energy recovery and recycling,and zero-liquid-discharge processes is driving the rapid evolution of dual-membrane technology toward low-carbon energy efficiency and resource circularity.These advancements establish a critical technological foundation for constructing sustainable water cycle systems that address both water security and environmental resilience.
