摘要
指出了土壤的重金属污染已成为环境污染的重大问题,土壤修复技术的研究与应用已经成为一个热点。针对我国土壤重金属污染现状,概述了化学淋洗修复技术,包括原位化学淋洗技术和异位化学淋洗技术,并分析了影响其修复效果的因素,着重介绍了主要的淋洗剂及其研究进展,针对化学淋洗技术存在的问题提出了其今后研究的重点,以期为土壤重金属污染防治提供参考。
Soils polluted by heavy metals have become a very important problem of environmental pollution and the study and application of soil remediation technology become a focus. This paper summarized the chemical washing technique including in--situ/ ex--situ chemical washing and analyzed the factors which effect the result of remediation according to the situation of heavy--metal contaminated soils in China. Meanwhile the maineluants were introduced in detail as well as their research advances. Finally the research emphasis in future was proposed for the existing problem of soil washing technology, in order to provide reference for the prevention and controlof soil heavy metal pollution.
