摘要:
在对徐州地区生活垃圾填埋场调查分析的基础上,根据填埋特征和地质状况选取4座典型填埋场为调查对象,采用ICP-MS对垃圾渗滤液及地下水中26种重金属进行监测分析。结果表明,在4个垃圾填埋场地下水及渗滤液中ρ(Sr)均相对较高(>700 μg/L);地下水中金属元素均正在以Ca,Mg为主向Na,Mg为主转化;地下水中Al,B质量浓度大小顺序为Y场(雁群)>S场(睢宁)>C场(翠屏山)>P场(邳州);4个垃圾填埋场共同典型重金属污染物为Mn,Fe,Zn,Ba;除上述污染物外,Y场地下水潜在典型重金属污染物为Pb和 Mo;S场为Mo和As;C场为Tl和Co;P场为As。

Abstract:
Based on investigation and analysis of municipal solid waste landfills in Xuzhou area,four typical landfills were selected as the research objects according to geological conditions and landfill characteristics. A total of 26 heavy metals from the waste leachate and groundwater were monitored and analyzed using inductively coupled plasma mass spectrometry (ICP-MS). The results showed that the mass concentrations of the Sr element were relatively high (>700 ug/L) in the groundwater and leachate for all four landfills,and that the main elements in groundwater were gradually shifting from Ca and Mg to those of Na and Mg. The mass concentrations of the Al and B elements in groundwater were descending in the order of the Y (Yanqun),S (Suining),C (Cuiping Mountain),and P (Pizhou) landfill. The common typical heavy metal pollutants of the four landfills were Mn,Fe,Zn,Ba. In addition,Pb and Mo were potential typical heavy metal pollutants in the Y landfill groundwater,and for the S landfill,they were Mo and As. Tl and Co were potential typical heavy metal pollutants in the C landfill groundwater,and for the P landfill,it was As.
