国际污染场地土壤修复技术综合分析

针对土壤污染日益严重的问题,我国《重金属污染综合防治"十二五"规划》明确将重金属污染土壤列为主要整治内容之一。文章综合分析了国内外污染场地土壤修复技术的研发历程、运用现状;指出了国际土壤修复技术现已进入黄金期;比较了欧美国家运用于污染场地土壤修复主要技术的优缺点;介绍了最新的污染土壤植物修复技术的发展与应用;同时结合"十五"和"十一五"国家"863"计划,给出了我国污染场地土壤修复技术研发现状示意图,以及我国土壤修复技术研发和应用路线图;在此基础上提出了污染场地土壤修复技术的四大需求、四大发展方位和六大发展方向,并从六方面指出我国与发达国家土壤修复技术存在的差距,初步提出了我国污染场地土壤修复技术发展建议。

Comprehensive Analysis on Soil Remediation Technologies of International Contaminated Sites

To the question of contaminated soil,the soil contaminated by heavy metals has been listed as one of the main improvement content in Comprehensive Prevention and Control of Heavy Metal Pollution in 12th Five-Year Plan in China.The research and development process,using the status quo of soil remediation technologies(SRTs) at home and abroad were analyzed to indicate that international SRTs have entered into gold period.SRTs in the Occident were compared to evaluate their superiority and inferiority.Development and application of the latest phytoremediation technologies were introduced.In combination with national 10th Five-Year and 11th Five-Year "863" Plan,research status scheme and research-application roadmap of SRTs of contaminated sites in China were designed,based on which the demands,development orientations and development directions of SRTs were proposed.The gap of SRTs between China and developed countries were illustrated,and then some advices of SRTs in China were proposed.
