济南市垃圾填埋场对地下水环境的影响分析

Impact analysis of landfill in Jinan on the groundwater environment

介绍了济南市垃圾填埋场的建设概况,分析了垃圾填埋场渗滤液的污染特性。通过对填埋场周围地下水质的监测,采用标准指数法评价了填埋场周围地下水的环境质量,并据此分析了填埋场建设对其周围地下水环境的影响。结果表明目前该区域的地下水环境已经受到了填埋场渗滤液的污染,但污染范围及程度有限。浅层地下水环境已形成了以污水处理站蓄水池为中心的污染区域,超标区域主要位于蓄水池偏西北方向,主要超标污染物有高锰酸盐指数、氨氮和挥发酚等。随着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。

The general situation of the landfill in Jinan has been introduced and the pollution characteristic of the refuse leachate has been analyzed in this paper. Based on monitoring data from around the landfill, groundwater quality has been assessed by standard index, and the impact of the landfill on the groundwater environment has been analyzed, as well. The result showed that the groundwater environment has been polluted by the landfill leachate to some extent. The polluted zone for shallow layer groundwater environment is centered on the reservoir of sewage farm with northwest direction. The chief pollutants were CODMn, NH3-N and volatile phenol, etc. It is necessary that the extent of polluted area should be analyzed further with the landfill constructing.
