摘　　要：治理重金属污染河流底泥的生物技术是指利用生物体来消除或降低重金属毒性的方法,包括微生物修复、植物修复和植物-微生物联合修复,具有成本低、去除效率高、脱毒后污泥脱水性能好等优点,近年来在国际上备受关注。本文介绍了近10年来生物技术在治理重金属污染河流底泥方面的研究成果,着重介绍了日益受关注的生物淋滤技术,从微生物学、分子生物学和生物表面活性剂等方面的发展作了详细描述,展望了生物修复在河流底泥重金属污染应用中的前景。The biological technique to remediate river sediment polluted by heavy metal is a method to remove heavy metal or to reduce its toxicity from sediment, which includes microbial remediation, phytoremediation and phyto-microbial remediation. It has received wide attention for its advantages of low cost, high efficiency and dehydration. In this paper the progress of the biological technique to remediate heavy metal polluted river sediment during last decade was summarized. The bioleaching technique was described in detail from aspects of microbiology, molecubr biology and biosurfactant. The prospect of biological remediation of polluted sediment was also discussed.
