摘要
我国土壤和地下水污染形势严峻,污染场地数量巨大、类型复杂,相应的管理和修复技术体系仍然滞后.监控自然衰减(MNA)作为一种基于污染风险管控的场地修复和长期监测方法,是土壤和地下水污染修复中较为经济和有效的方法之一,可以实现修复的成本效益最大化.近几年来MNA在美国污染场地修复中的应用比例约占30%左右,场地修复的平均成本为数十万美元.本文介绍了MNA方法的来源和发展,总结了MNA的国内外研究应用进展和相关的核心技术手段,与典型修复方法的成本进行了比较,以期为MNA相关的研究和应用提供参考借鉴.
Severe and widespread pollution of soil and groundwater in China has caused intensive concerns, with greatnumber of contaminated sites and diversified pollution types, for which there is a development lag in site management andremediation technologies. As a non-invasive long-term management approach based on risk control over contaminatedsites, Monitored Natural Attenuation （MNA） turns out as an effective and economic strategy for soil and ground waterpollution management with the potential for maximized cost-effectiveness. In the United States, application of MNA incontaminated site remediation accounts for about 30%, and the cost is about several hundred thousand dollars. This articlegives a brief on the origination and evolution of MNA, followed with a summary of progress and highlights in research onMNA as well as their recent applications, both domestic and overseas. A comparison between MNA and typical remedialtechnologies is made, and this is expected to serve as a reference for the research and applications of MNA-relatedtechnologies.
