摘要
某些垃圾填埋场由于相关资料严重缺失,给污染物的治理工作带来了困难.为了解决老垃圾填埋场的污染物治理问题,将高密度电法和探地雷达法相结合,对某村老垃圾填埋场进行了全方位探查,取得了以下成果:1)成功识别出垃圾与原位土层的界线,得到了垃圾层的范围和厚度,并以此为基础计算出回填方量为132 454 m3,为污染物的清除和治理提供了重要的参考;2)依据电阻率的分布,划分出填埋物的种类主要为建筑垃圾、生活垃圾或者粪便;3)识别出垃圾渗液的污染范围,圈定需要隔绝污染和回收清洁土壤的位置.本次研究结果为今后的垃圾治理工作提供了重要的参考.
Abstract
In the process of urban development,because of the nearsightedness of local au-thorities,many landfill sites have been improperly located,and some old landfill sites have encountered difficulties in dealing with pollution due to the serious lack of relevant informa-tion.High-density resistivity method and ground-penetrating radar method are important ge-ophysical methods to investigate the burial depth and distribution of subsurface media.In or-der to solve the problem of pollutant treatment in old landfill sites,a combination of the two was used at the old landfill in a village to explore all aspects of the landfill,and the following results were obtained:1)The boundary between the waste and the in-situ soil layer was suc-cessfully identified,the extent and thickness of the waste layer were obtained,and based on this,the backfill volume of the waste was calculated to be 132 454 m3,which provided an important reference for the removal and treatment of pollutants;2)the type of landfill mate-rial was classified into construction waste,domestic waste or feces based on the resistivity distribution;3)Identifying the pollution range of landfill leachate and delineating the loca-tion are achieved where pollution and clean soil need to be isolated.The results of this study provide important references for future waste management work.
