摘要
土壤是生态环境的重要组成部分,与人类的生存和健康密切相关。土壤重金属污染问题是环境和土壤科学研究者关注的热点问题。对土壤重金属污染物来源的鉴别是准确、有效控制和治理污染源的前提。根据近年来国内外对土壤重金属污染的相关研究报道,综述了土壤中污染物的工业、农业和交通因子三大主要来源。目前重金属污染土壤修复主要采用工程技术、物理化学技术和植物修复技术。在此就修复技术的原理、适用范围以及研究现状与发展动态等方面进行了综述与分析。
The soil is an important component of the ecological environment,and it is correlation with human survival and health.Heavy metals contaminated soils is a the popular issue in the environment and soil science.Origin of heavy metals contaminated soils of soil identification is accurate,effective control and management of pollution origin premise.According to heavy metals contaminated soils in-country and abroad in recent years,relevant research reports,review of industrial pollutants in the soil,agricultural and transportation sources of the three main factors.At present heavy metal remediation of contaminated soils mainly in engineering,physical-chemical techniques and phytoremediation.In this paper,the principle of restoration techniques,application and the status and development trends and research areas were reviewed and analyzed.
