摘　　要：监测自然衰减技术(MNA)作为地下水修复的一种可选方法已得到普遍认可,应用监测自然衰减技术之前须进行自然衰减有效性评价。本文针对地下水氯代烃污染修复用的监测自然衰减进行了实验室小试研究,以四氯化碳等氯代烃污染地下水为研究对象,在实验室条件下进行监测自然衰减研究。通过实验组和对照组监测数据对比,分析监测自然衰减对氯代烃衰减的效果,其中四氯化碳衰减效果最佳,四氯乙烯等氯代烃衰减效果较好,低浓度的以四氯化碳为主的氯代烃污染场地可以采用监测自然衰减的修复技术进行修复。Monitored natural attenuation(MNA)has gained general acceptance as an alternative method for groundwater remediation,before the application of MNA,effectiveness evaluation of MNA should be carried out.In this paper,a laboratory small study on monitoring natural attenuation for remediation of chlorinated hydrocarbon pollution in groundwater was carried out,taking chlorinated hydrocarbons such as carbon tetrachloride groundwater as the research object,MNA studies are monitored under laboratory conditions.By comparing the monitoring data of the experimental group and the control group,analyzing the attenuation effect of natural attenuation on chlorinated hydrocarbons,carbon tetrachloride has the best attenuation effect,and chlorinated hydrocarbons such as tetrachloroethylene have the better attenuation effect,the low concentration of carbon tetrachloride as the main pollutant can be repaired by using MNA technology.
