国内外土壤砷污染及其修复技术现状与展望

Situation and Prospect of Soil Arsenic Pollution and Its Remediation Techniques at Home and Abroad

综述了国内外土壤砷污染现状,总结了固化稳定化修复、土壤淋洗修复、电动修复、微生物修复、植物修复和农业生态修复技术在土壤砷污染修复中的研究进展及各自优缺点,指出土壤砷污染修复未来研究的发展方向为:进一步研究修复过程中的影响因素及作用机理;开发新技术;注重多项技术联合修复土壤砷污染的研究。

The current status of the arsenic polluted soil at home and abroad was summarized. The research progress and advantages and disadvantages of the remediation techniques,including solidificationstabilization,soil washing, electrokinetic remediation, bioremediation, phytoremediation and agro-ecological restoration, were discussed. Meanwhile,prospects of arsenic pollution in soil were proposed： influencing factors and mechanism under arsenic contaminated soil remediation need to be researched and explored at higher level,new remediation techniques need to be developed,and the research and application of the combined remediation technologies need to be attached importance to.
