摘　　要：底泥是水体中重金属的主要富集地,底泥中重金属是水生环境中潜在的危险污染物,对水体生态环境具有重要的影响。当今,水体底泥重金属污染日益严重,河流、湖泊等水体底泥重金属污染问题已引起全世界的广泛关注。介绍了我国水体底泥重金属污染的现状,分析表明我国河流、湖泊等水体底泥已受到不同程度的重金属污染。总结了物理修复、化学修复、生物修复技术对底泥重金属修复的优点和缺点,以及国内外各学者对物理、化学、生物修复技术的研究进展,以期为我国水体底泥重金属污染治理提供一定参考。Sediment is the main enrichment matter of heavy metals in water,and heavy metals containing in sediments are endangering the aquatic environment. Nowadays,the pollution of heavy metal in the sediment of water body is becoming more and more serious. The pollution of heavy metals in the sediment of rivers and lakes attracted worldwide attention. In this paper,the present situation of heavy metal pollution in the sediments of water bodies in China was introduced,which showed that the sediments of rivers and lakes had been polluted by heavy metals in different degrees. In addition,the advantages and disadvantages of physical,chemical and bioremediation technologies for heavy metal remediation in sediments were analyzed,and the research progress of physical,chemical and bioremediation technologies was provided to some scholars at home and abroad,which would provide references for the remediation of heavy metals contamination in sediment.
