摘　　要：选取典型非正规垃圾填埋场作为研究对象,对比不同整治手段对垃圾填埋场及周边地下水质量产生的影响,并揭露不同整治过程对地下水造成二次污染的风险。结果表明,异地处理堆放点及周边地下水水质呈现改善指标数量多、污染物浓度下降幅度大且大部分达标的特点;就地处理堆放点及周边地下水水质呈现改善指标数量少、污染物浓度下降幅度小且缓慢的特点;异地处理相比就地处理导致渗滤液泄漏污染地下水的风险更高。但随整治时间的延长,异地处理由于对污染源的消除更彻底,呈现明显改善地下水质量的效果。Typical informal landfills was selected as the research object,the impact of different remediation methods on the quality of landfills and surrounding groundwater were compared,and the risk of secondary pollution of groundwater caused by different remediation processes was revealed.The results showed that the off-site treatment stacking point and surrounding groundwater quality had the characteristics of a large number of improvement indicators,a large decreased in pollutant concentration,and most of them met the standards.And the on-situ disposal sites and surrounding groundwater quality were characterized by a small number of improvement indicators and a small and slow decline in pollutant concentration.Compared with on-situ treatment,off-site treatment had a higher risk of leachate leakage and groundwater pollution.However,with the extension of remediation time,off-site treatment has the effect if significantly improving the groundwater quality due to the more thorough elimination of pollution sources.
