磁分离技术在水处理中的研究现状及开发钢渣磁种的可行性

Research Status of Magnetic Separation Technology in Water Treatment and the Feasibility of Developing Steel Slag as Magnetic Seed

简述磁分离技术的基本原理,总结国内磁分离技术在水处理中的研究现状,主要有含油废水、印染废水、含重金属离子废水以及含磷废水等,并指出磁种的选择在磁分离技术发展中的重要性,现有的新型磁种有炼钢厂排放的烟尘和气溶胶凝聚物、粉煤灰等,以此为基础分析了钢渣的磁性质以及作为新型廉价磁种的可行性。

The basic principle of magnetic separation technology was briefly described.The research sta-tus of magnetic separation technology in water treatment-including oil-bearing wastewater,printing and dyeing wastewater,heavy metal ion-bearing wastewater and phosphorus wastewater,etc,were summarized in the do-mestic.The importance of choosing magnetic seed in the development of magnetic separation technology was pointed out.Study on new magnetic seed such as soot and aerosols condensate emitted by steel plant,fly ash, etc.has exited,on basis of that the magnetic properties of the steel slag as well as the feasibility of the new low-priced magnetic seed were analyzed.
