摘要
针对简易生活垃圾填埋场内垃圾渗滤液在降水或地下水渗流运动作用下扩散,对地下水造成污染的问题,对华北地区某生活垃圾填埋场地块进行调查,在资料搜集、知情人员访谈、水文地质调查的基础上,识别出潜在污染物特征指标,科学合理地布置地下水采样点采集地下水水样;采用单因子污染指数法,以GB/T 14848—2017《地下水环境质量标准》中Ⅳ类标准指标为评价标准,通过对地下水上游对照点、垂直地下水流向的扩散点、下游扩散点水样试验结果的比较分析,查明了填埋场地块内污染物分布及扩散范围。
In order to solve the problem of groundwater pollution caused by the diffusion of landfill leachate in simple domestic refuse landfill under the action of precipitation or groundwater seepage movement.This paper takes the investigation of a landfill site in North China as an example,and on the basis of data collection,informed personnel interview and hydrogeological investigation,identifies potential pollutant characteristic indicators,scientifically and reasonably arranges groundwater sampling points to collect groundwater samples.Based on the single factor pollution index method,using the Class IV standard indicators in the"GB/T 14848-2017 Groundwater Environmental Quality Standards"as the evaluation criteria,by comparing and analyzing the water sample test results of the upstream control point,vertical groundwater flow diffusion point,and downstream diffusion point of groundwater,the distribution and diffusion range of pollutants in the landfill site were identified.
