重金属与多环芳烃复合污染土壤的分布特征及修复技术研究进展

Research Progress on Distribution and Remediation Technologies for the Combined Pollution of Heavy Metals and Polycyclic Aromatic Hydrocarbons in Soil

摘要: 土壤中污染物通常以复合污染的形式存在，各种污染物之间的相互作用增加了修复的难度，仅针对单一污染物进行治理通常难以达到土壤修复的要求。该文对重金属与多环芳烃复合污染的分布特征及两者之间的交互作用进行了总结，综述了几种复合污染土壤修复技术（淋洗法、植物修复、微生物修复和电动法）的作用机理及适用条件，并对该类型复合污染土壤修复技术的研究方向提出了展望。

Abstract: The contaminants in soil usually exist in the form of combined pollution, and the interactions between various contaminants make it more difficult to remediate, so that treatment technologies for single contaminant is difficult to meet the requirement of soil remediation. This study summarizes the distribution of heavy metals and polycyclic aromatic hydrocarbons combined pollution, and the mechanisms and application conditions of several kinds of soil remediation technologies, such as soil washing, phytoremediation, microbial remediation and electrokinetic processing. It focuses on putting forward the prospect of further study on combined pollution soil remediation of the above mentioned contaminants.
