VOCs污染场地地下水监测式自然衰减法可行性评估程序研究

挥发性有机污染物（VOCs）是我国污染场地地下水中高频检出的污染物,在地下水中多以非水相液体（NAPL）形式存在,成为持久的污染源,具有较高的环境和健康风险.监测式自然衰减法修复技术（MNA）可以单独使用,也可以和其他修复技术联合使用,具有费用较低、不会造成其他负面影响等优势,作为地下水污染修复的一种可选方法已得到普遍认可,执行监测式自然衰减法前必须进行自然衰减可行性评估,实施监测式自然衰减法修复技术,具有良好的发展前景.概述了目前国内外主要的地下水中VOCs自然衰减修复技术的研究进展.地下水中VOCs自然衰减可行性评估程序研究的开展,可以为我国制定利用MNA技术修复污染场地章程和规章以及保障地下水安全提供可靠的科学依据.

Research on the feasibility assessment programs of Monitored Natural Attenuation in Contaminated Aquifers of Volatile Organic Contaminants contaminated sites

Volatile organic pollutants （VOCs） in non- aqueous phase liquid （NAPL） form are among the most frequendy detected pollutants in groundwater of industrial contaminated site of China. Monitoring natural attenuation （MNA） has gained more and more attention in recent years, which will not result in other negative effect with low cost. MNA ＇is an optional remediation method for contaminated groundwater, which has been commonly accepted. It is necessary to evaluate effectiveness of natural attenuation before implementing MNA. In this paper, it was reviewed for international and domestic research advances on natural attenuation for VOCs in groundwater. Research on the feasibility assessment programs of Mo- nitored Natural Attenuation in Contaminated Aquifers of Volatile Organic Contaminants contaminated sites, which will provide the reliable scientific basis for our country to draw up rules and regulations of making use of MNA technical to repair contaminated site, and to protect the safety of groundwater.
