重金属污染土壤的修复与修复效果评价研究进展

Research Progress in Remediation and Its Effect Evaluation of Heavy Metal Contaminated Soil

随着工农业的迅速发展,土壤污染已经成为当今面临的一个重要环境问题,而土壤的重金属污染又是其中重要的部分。重金属污染土壤的修复方法主要有物理方法、化学方法、生物方法,并随着研究的深入,提出了联合修复方法。针对中国土壤重金属污染的来源、现状和各种修复方法的机理、优缺点、修复标准、修复后的评价方法以及国内外的研究进展情况展开讨论,并提出今后研究中存在的科学问题,对未来的发展进行了展望,以期对后续的重金属污染土壤的修复研究工作有所帮助。

With the rapid development of agriculture and industry, soil contamination has become a very serious environmental problem facing today, while the contamination of soil by heavy metals is one of the important parts. Physical remediation and chemical remediation and bioremediation are the important methods for solving heavy metal pollution in soil, combined remediation is raised as the research continues. The sources and current situation of soil heavy metal contamination in our country and its repair mechanism, advantages and disadvantages, the standards and evaluation methods after remedlation and research progresses both in domestic and abroad are discussed carefully in the text, on this basis, the author comes up with some issues in the future research and looks forward to the future, in order to have contributions to subsequent researches.
