摘　　要：废水中的金属元素是污染环境的主要因素之一,对废水中的金属元素进行分离回收可以充分利用资源,减少污染。通过膜分离技术进行二次金属资源的回收和水的回用处理已有大量研究,并在工程实践中获得效益。综述了几种常见的膜分离技术,分析了各种技术在金属分离及回收中的适用条件和局限性,并对膜分离技术在金属废水资源化中的应用前景及发展进行了展望。The main factor of environmental pollution is metal elements in wastewater. The separation and recovery of metal elements from wastewater can make full use of resources and reduce pollution. Numerous researches on the secondary recovery of metal resources,as well as the reuse and treatment of water,by membrane separation technology are accomplished,and benefits have been obtained in engineering practice. Several kinds of common membrane separation technologies are summarized. Appropriate conditions and limitations of various kinds of metal separation and recovery technologies are analyzed. The application prospect and development of membrane separation technology for the utilization of metal-containing wastewater are predicted.
