某正规垃圾填埋场封场前后地下水环境质量评价研究

Study on Evaluation of Groundwater Environmental Quality before and after Closure of A Formal Landfill Site

通过对某正规垃圾填埋场封场前后进行地下水环境质量评价,旨在明晰填埋场运行对周围地下水环境的影响。通过选取封场前后地下水样品,进行较为全面的重金属检测及常规地下水质量分析,主要包括溶解性固体总量、高锰酸盐指数、氯化物、重金属含量等多种水质监测指标,评估地下水环境质量的变化。研究结果表明,填埋场封场后地下水环境质量得到一定程度的改善,封场措施能够有效减少有害物质的渗漏。

An evaluation of groundwater environmental quality before and after the closure of a regulated landfill site was conducted,aiming to elucidate the impact of landfill operations on the surrounding groundwater environment.By selecting groundwater samples before and after closure,a comprehensive analysis of heavy metals and routine groundwater quality was performed,including parameters such as total dissolved solids,permanganate index,chloride and heavy metal concentrations.The changes in groundwater environmental quality were evaluated.The research results indicated that the groundwater environmental quality was improved to a certain extent after the closure of the landfill,suggesting that the closure measures effectively reduced the leakage of harmful substances.
