摘要
地下水重金属污染已成为人们日益关注的环境问题。目前的修复技术主要有原位修复和异位修复两类。由于突发性重金属污染事件有一定的不可预见性和不可控制性,对于原位修复,一定要重视污染现场研究,以便将实验室研究更好地应用到实际中。由于异位修复能够直接、快速、高效地去除重金属污染物,因此比较适用于修复突发性重金属污染地下水。而联合运用多种技术进行集成将成为突发性重金属污染地下水应急处理技术的发展方向。
Heavy metals are a serious threat for ecosystems and human beings. Heavy metals in groundwater pollution has become a topic of increasing concern to the people. The current remediation methods in use are in-situ remediation and ex-situ remediation. However,the outburst of heavy-metal contamination is ,to some extent,unpredictable and tend to be out of control. Based on the mentioned characters of the contamination,for in-situ remediation,attention should be focused on field studies,since lab studies should find its more application for the field eventually. Ex-situ remediation could remove heavy metal directly,with great quickness and efficiency,which more fit to the restoration of unexpected heavy metal contamination of groundwater. The joint use of a variety of techniques is the prospective development of emergency treatment of heavy metals pollution in groundwater.
