地下水铅污染修复技术应用与研究进展

Progress on Technology for Pb Contamination of Groundwater Remediation

铅是地下水重金属污染中的主要元素,目前的修复技术主要分为物理屏蔽法、抽出处理法和原位修复法。抽出处理法包括物理、化学和生物的方法,原位修复法是目前该领域的主要研究方向,包括渗透反应格栅、生物修复以及动电处理技术等。文章介绍了铅污染的主要来源及对环境和人体造成的危害,结合近几年国内外有关地下水铅污染的主要科研成果,对各种修复技术的原理、优缺点进行了综合的述评,并对今后的研究方向提出了一点建议。

Pb as a major element in heavy metals that contaminated groundwater, the remediation methods in use include physical screening, extraction and in situ remediation. The later is mostly developed for time being, which includes PRB, bioremediation and electrokinetic remediation. Major source and impact of Pb contamination were introduced, a number of benchmark projects related to control of lead pollution in groundwater were reviewed and future study was prospected as well.
