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 society and economy, the process of industrial and agricultural processes will pollute the environment more and more, which will also endanger human health. In recent years, many emerging environmental pollution treatment technologies have emerged. These emerging technologies can effectively repair pollutants and cause little environmental pollution, and have become the research hotspots of experts and scholars both at home and abroad. Magnetic nanoparticles with small size effects, surface effects and magnetic properties and other characteristics of the adsorption of pollutants have a strengthening effect. Environmental biotechnology treatment efficiency, no secondary pollution, has also been widely used in environmental management. In this paper, the preparation and application of magnetic nanoparticles in water biological treatment, soil bioremediation and environmental monitoring technology are introduced. The advantages and disadvantages of nano-biological combined technology and their application development prospects are analyzed in order to provide scientific basis for environmental pollution Governance provides new ideas.
