摘　　要：随着磁分离技术的发展,磁分离已从传统选矿应用扩展到废气、废渣、废水处理等环保领域。高梯度磁分离(HGMS)技术作为一种新型的水处理技术,目前已在分离废水中的磁性物质及COD5等有机污染物方面已得到广泛应用,超导高梯度磁分离技术在分离重金属离子等微粒径无磁性污染物方面的研究也成为热点,具有污染物去除效率高、节能环保和设备简单等优势。本文介绍了此技术的基本原理,综述了国内外学者应用该技术处理重金属废水的研究现状,并做出了展望。With the development of magnetic separation technology, the technology has extended from the traditional dressing to the field of waste gas, waste residue, waste water treatment and other en-vironmental protection. As a new water treatment technology, high gradient magnetic separation (HGMS) technology has been widely applied in the separation of magnetic material and COD5 of organic pollutants in wastewater. Study of superconducting high gradient magnetic separation technology with advantages as high removal efficiency, energy saving and simple operation in the separation of small particle size and nonmagnetic contaminants such as heavy metal ions has be-come a hot research topic. This paper introduces the basic principle of this technology, the research results of this technique for the treatment of heavy metal wastewater at home and abroad, and has made the forecast.
