摘要
工业化进程的不断推进和人类生产活动的不断影响,引发了严重的土壤重金属污染问题。由于重金属污染物具有隐蔽性高、易积累、难以迁移及危害效果显著等特点,因此土壤重金属污染较大气污染和水污染引起的危害更加严重。笔者从土壤重金属污染现状所引发的危害出发,综述了物理化学修复技术、生物修复技术以及联合修复技术在土壤修复方面的应用,以期为我国土壤重金属污染防治修复工作提供参考借鉴。
With the continuous advancement of the industrialization process and the continuous impact of human production activities,heavy metal pollution in soil has become a serious problem.Because heavy metal pollutants have the characteristics of high concealment,easy accumulation,difficult migration,and significant hazard effects,soil heavy metal pollution is more serious than air pollution and water pollution.Based on the harm caused by the status quo of soil heavy metal pollution,the author reviews the application of physical and chemical remediation technology,bioremediation technology,and combined remediation technology in soil remediation,in order to provide some reference for the prevention and repair of soil heavy metal pollution in China.
