摘　　要：底泥是湖泊重要的内源污染来源,关于底泥污染控制的研究近年来受到广泛重视。目前对底泥污染的控制技术主要包括原位处理技术和异位处理技术。原位处理技术主要包括钝化、覆盖、生物修复等。钝化技术是一种高效的湖泊内源污染控制技术,它通过抑制内源营养盐的释放来控制水体营养盐含量。文章综述了底泥原位钝化技术的研究及其应用情况;分析了原位钝化技术的特点及主要功能;介绍了常用底泥钝化剂的应用情况以及新型钝化剂的研究进展;并对原位钝化技术的未来发展进行了展望。Sediment is one of the most important sources of internal pollution in lakes.Pollution control of contaminated sediment has become a hot topic in recent years.Sediment pollution control techniques mainly contain the in-situ treatment technology and off-site treatment technology.In-situ treatment technology mainly includes inactivation,capping and bioremediation.Among them,inactivation technology is a highly effective technique to reduce internal nutrient loading.It can lower the lake′s nutrient content by retarding nutrient release from polluted sediments.In the paper,the studies and applications of in-situ inactivation technology were summarized.The characteristics and main function of in-situ inactivation technology were discussed.The applications of common inactivation agents,as well as the research advances of new inactivation agents were introduced.Furthermore,the research prospects for the in-situ inactivation technology were also proposed.
