金属材料在水处理技术中的应用现状及发展趋势

Current status and development of metallic materials applied to the technique of water treatment

随着水污染的日益加重 ,各种水处理技术应运而生 ,金属材料以其独有的优势在水处理技术中得到广泛应用。综述了铝、铜、锌、镁、贵金属、稀土合金特别是铁及铁 -Me(Me指铁以外的金属 )体系等各种金属材料在含重金属离子废水、染料废水、含多氯有机物废水、城市生活污水等废水处理技术中的应用现状 ,并提出了今后应予以重点发展的建议。

With the deterioration of water pollution, the technique of water treatment for all kinds of wastewater has been explored. Metallic materials are widely used in the technique of water treatment because of its unique advantage. The current status of all kinds of metallic materials such as aluminium ,copper, zinc, magnesium , precious metals, rare earth alloys especially iron and iron-Me(Me refers to the metals except iron) system applied to the treating technique for wastewater containing heavy metal ions, dyestuff, polychloride and civic sewage is summarized.The suggestion of developmental emphasis in this field is also put forward.
