摘　　要：为充分发挥生物质炭多孔性、表面活性、选择性吸附和高碱性等性能在有效控制重金属生物迁移中的作用,以期为重金属污染土壤修复技术提供参考。介绍了我国重金属污染土壤的概况,综述了生物质炭在重金属污染土壤修复中的应用,重点介绍了植物修复、化学淋洗、土壤性能改良、固化/稳定化、热解吸修复和电动力学修复等技术的应用情况,简要概述了原料种类、热解温度和表面官能团对生物质炭性质及生物质炭对土壤环境的影响,并展望了生物质炭在重金属污染土壤修复中的发展前景。The role of biomass charcoal porous,surface activity,selective adsorption and high based properties in the effective control of heavy metal biological migration was given in order to provide reference for heavy metal contaminated soil remediation technology. The general situation of heavy metal contaminated soil in China was introduced and the application of biomass carbon in heavy metal contaminated soil remediation was reviewed. The effects of phytoremediation,chemical leaching,soil performance improvement,curing/stabilization,thermal desorption repair and electrokinetic repair were highlighted. The effects of raw material types,pyrolysis temperature and surface functional groups on biomass carbon and biomass carbon on soil environment were briefly introduced. The future of biomass charcoal application in heavy metal contaminated soil remediation was prospected.
