几类金属材料在水处理中的应用

随着工业的发展，大量的污水被排入江河湖海，水质日益恶化，各种水处理技术也应运而生，金属材料以其独有的优势在水处理技术中得到了广泛的应用。本文综述了铁在工业废水中的应用现状以及铜锌合金在饮用水、微污染原水和反渗透、离子交换树脂预处理系统中的应用现状，并探讨了这些技术存在的优缺点和未来的发展方向。

Application of Several Kinds of Metallic Material in Water Treatment

With the development of industry, a large number of sewage has been discharged into rivers, lakes and sea. Water quality has been become deterioration, also all kinds of techniques of water treatment have been taken forth. Metallic materials are widely used in the techniques of water treatment because of its unique advantages. It is reviewed that iron is used in industry wastewater treatment and Cu-Zn alloy is used in drinking water treatment,slightly polluted water treatment and pretreatment systems of reverse osmosis and ion exchange resin. The advantage, disadvantage and future development of this technology with using metallic material in water treatment were discussed.
