为研究垃圾填埋场对土壤和地下水的长期影响,以河北某垃圾填埋场为研究对象,利用SH-30 钻机进行钻探并建井,采集土壤和地下水样品,分析近三年填埋场内土壤和地下水污染物的变化趋势.结果表明,土壤中污染物无明显累积,填埋区周边地下水中铜、砷、锰、亚硝酸盐、耗氧量、硫酸盐、氟化物、溶解性固体总量、总硬度、挥发酚类近三年有明显累积,可见垃圾填埋对场区内地下水环境存在影响.
For the studying on long-term impact of landfills on soil and groundwater,taking a landfill in Hebei as the research object,the SH-30 drilling rig was used to drill and build wells,collected soil and groundwater samples,and analyzed the landfill trend in soil and groundwater contaminants in the past three years.The results showed that there was no obvious accumulation of pollutants in soil,and copper,arsenic,manganese,nitrite,oxygen consumption,sulfate,fluoride,total dissolved solids,total hardness,and volatile phenols in the groundwater around the fill area were accumulation significantly in the past three years.So the landfill has an impact on the groundwater environment in the site area.
