摘　　要：目前钢渣的改性方式主要有无机改性、高温活化改性和复合改性等,通过分析钢渣吸附废水中重金属离子的作用机理,得出钢渣的改性方式主要是通过增强钢渣的物理吸附和静电引力作用为主。文章对改性钢渣用于水处理领域的发展现状、存在问题及未来发展方向做出阐述。At present,the main modification methods of steel slag are inorganic modification,high temperature activation modification and composite modification.By analyzing the mechanism of heavy metal ions adsorption on steel slag in wastewater,it is concluded that the modification methods of steel slag are mainly through enhancing the physical adsorption and electrostatic attraction on steel slag.The present situation,existing problems and future development direction of modified steel slag used in water treatment are described in this paper.
