摘要
我国土壤污染防治形势严峻,区域性、流域性土壤污染态势依然突出,土壤污染风险加大,农产品质量安全、人居环境安全和生态环境仍然面临较大威胁.本文主要分析了目前我国污染土壤化学淋洗修复技术的研究现状与研究进展,着重分析了淋洗修复过程中淋洗药剂的种类、pH,淋洗时间、淋洗剂的使用量等因素对淋洗修复效果的影响.同时在常规的淋洗技术基础上,本文也分析了超声强化、微波强化、化学氧化/还原强化等物理强化和化学强化淋洗技术研究进展,为土壤淋洗技术的研究作了进一步概述,并在最后对污染土壤淋洗修复技术进行了一系列展望.
Abstract
The situation of soil pollution prevention and control in China is grim,the trend of regional or regional soil pollution is still prominent,the risk of soil pollution is increasing,and the quality and safety of agricultural products,the safety of human settlements and the ecological environment are still under great threat.This paper mainly analyzed the current research status and progress of chemical clap remediation technology in contaminated soil in our country,focusing on the effects of the factors such as the type,pH,time and dosage of clap remediation on the effect of clap remediation.At the same time,on the basis of conventional leaching technology,this paper also analyzed the research progress of physical and chemical enhanced leaching technology,such as ultrasonic enhancement,microwave enhancement,chemical oxidation/reduction enhancement,and made a further review for the research of soil leaching technology,and finally made a series of prospects for the remediation technology of contaminated soil leaching.
