摘　　要：随着社会经济的发展,工农业等过程对环境造成污染的日益严重,对人体健康也会造成危害。近年来出现了许多新兴的环境污染处理技术,这些新兴技术能够对污染物进行高效修复,对环境污染小,成为当前国内外各专家学者的研究热点。磁性纳米颗粒具有小尺寸效应、表面效应以及磁学性质等特性,对污染物的吸附具有强化作用。环境生物技术处理效率高、无二次污染,也被广泛应用到环境治理中。文章介绍了磁性纳米颗粒的制备及其在水生物处理、土壤生物修复以及环境监测技术中的研究进展和应用,分析了纳米-生物联合技术的优势和缺陷及其应用发展前景,以期为环境污染治理提供新的思路。With the development of social economy,industry,agriculture and other processes all do serious damage to both the environment and our health. There have been many new pollution treatment technologies in recent years,which can remediate the pollutants effectively and produce little pollution to the environment. So they become a hot point of the research at home and abroad. Magnetic nanoparticles which have characteristics of small size effect,surface effect and magnetic properties,have enhanced the adsorption of contaminants. Environmental biotechnology has also been widely applied to environmental governance because of its high processing efficiency and no secondary pollution. The article introduces the preparation method of magnetic nanoparticles and their research progress and application in biological treatment of water,soil bioremediation and environmental monitoring technology. It also analyzes the advantages,disadvantages and prospects for the development of applications of nano-bio joint technology,which would provide a new method for control of environmental pollution.
