摘要
介绍了土壤中重金属的来源和形态,综述了当前土壤修复常用的物理、化学和生物修复法的原理和特点,对比了各方法的优点、局限性及其实用性,并对土壤修复技术今后的研究方向进行了展望。
Along with the urban expansion and the development of industry and agriculture,heavy metals pollution in soil is increasingly serious,which has already threatened the ecological environment and human health.This pa-per touched the remedial principle and technical characteristics of physical remediation,chemical remediation and bio-remediation,also discussed their advantages,disadvantages,feasibility and future research trends of the tech-nologies.
