摘要
垃圾填埋是我国目前处理城市生活垃圾的主要方式,由此引发的垃圾填埋场渗滤液对地下水污染已成为当前主要的水环境污染。选择唐山市某垃圾填埋场为研究对象,通过对垃圾填埋场周围布孔,对地下水取样和监测,分析了垃圾填埋场对其周围地下水环境的影响。结果表明地下水中污染因子主要为COD、NH4+-N、NO3-N、总硬度及溶解性总固体。目前该区域地下水已受到垃圾填埋场渗滤液的污染,在第四系地层保持完整而不被破坏的情况下,形成的地下水污染晕深度不超过30m。随着垃圾填埋场运行时间的延长,垃圾渗滤液对周围浅层地下水环境的影响范围及程度还有待于进一步研究。
Landfill is currently the primary solution to handle the municipal garbage in China~ however, the leachate from the landfill can cause groundwater contamination, which may become the main source for the current water pollution. In this study, a municipal landfill in Tangshan City is selected to investigate its effects on the adjacent groundwater environment. Groundwater samples were collected from several boreholes, and these samples were performed laboratory analysis to assess the current groundwater conditions in the study area. Results indicate that the main groundwater pollution factors are COD, NH4 +- N, NO3-N, total hardness, and total dissolved solids. Moreover, the results imply that groundwater has been affected by the leachate from the landfill in the study area, and the depth of the groundwater pollution halo is less than 30 m on the basis of the intact Quaternary strata. With the continuous landfill operation, the effects of the leachate from the landfill on the surrounding shallow groundwater environment still need future studies.
