垃圾填埋场周边地下水中重金属分布特征及运移预测

Distribution characteristics and migration prediction of heavy metals in groundwater around landfill site

地下水质量与污染调查作为如今地下水科学领域热门研究内容之一,是地下水资源管理的前提。近年来。非正规填埋场、未按标准建设防渗设施等的填埋场以及封场后未经严格维护的填埋场的存在,对填埋场周边的大气、水、土壤等都造成了严重的污染隐患,本文通过对垃圾填埋场的水文地质和工程地质条件进行调查,评价了垃圾填埋场地下水的质量状况和地下水中重金属超标组分分布特征,并预测垃圾填埋场封场后重金属超标组分在地下水中的运移情况,能为垃圾填埋场场地及周边地下水污染评估和地下水污染防治提供实例借鉴和科学依据。

As one of the most popular research contents in the field of groundwater science,groundwater quality and pollution investigation is the premise of groundwater resources management.In recent years.The existence of informal landfills,landfills that have not built anti-seepage facilities in accordance with standards,and landfills that have not been strictly maintained after closure has caused serious damage to the atmosphere,water,and soil around the landfill.Pollution hazards.In this paper,by investigating the hydrogeological and engineering geological conditions of the landfill site,the quality of the landfill site water and the distribution characteristics of the heavy metals in the groundwater are evaluated,and the heavy metals are predicted after the landfill is closed.The migration situation in groundwater can provide practical examples and scientific basis for landfill site and surrounding groundwater pollution assessment and groundwater pollution prevention and control.
