| 非正规生活垃圾填埋场产生的垃圾渗滤液极易造成土壤、地表水及地下水环境污染，严重威胁地下水安全及周边生态环境。采用单一方法无法准确评价非正规生活垃圾填埋场对浅层地下水环境影响，本文综合单项组分评价法、综合指数法、模糊评价法对非正规垃圾填埋场及周边浅层地下水样品点水质进行综合评价，对生活饮用水、工业用水及农业用水进行地下水用途功能评价。研究结果表明：垃圾填埋场浅层地下水受到严重污染，污染羽受地下水流向控制，已对下游及两侧浅层地下水环境质量及功能造成影响。其主要污染因子为总硬度、溶解性总固体、CODMn、NH3-N、SO42-、I-、Mn、As、Cd，污染严重的地下水中Cl-、Na+（K+）离子含量增高。，评价模式可为同类型场地评价提供参 |
| 英文摘要: |
| The landfill leachate produced by informal domestic refuse landfill is very likely to cause environmental pollution of soil， surface water and groundwater， which seriously threatens the safety of groundwater and the surrounding ecological environment. It is impossible to accurately evaluate the impact of informal domestic waste landfill site on shallow groundwater environment with a single method. In this paper， the single-component evaluation method， comprehensive index method and fuzzy evaluation method are integrated to evaluate the water quality of informal landfill site and surrounding shallow groundwater sample points， and to evaluate the groundwater use function of domestic drinking water， industrial water and agricultural water. The results show that the shallow groundwater of the landfill site is seriously polluted， and the pollution plume is controlled by the groundwater flow direction， which has affected the environmental quality and function of the shallow groundwater downstream and on both sides. The main pollution factors are total hardness， total dissolved solids， CODMn， NH3-N， SO42-， I-， Mn， As， Cd， and the contents of Cl- and Na+ （K+） ions in seriously polluted groundwater are increased. The evaluation model can provide reference for the evaluation of the same type of sites. |
