基于解析法的垃圾填埋场地下水环境影响评价

Environmental Impact Assessment of Groundwater in the Landfill Based on Analytic Method

为预测垃圾填埋场垃圾渗滤液收集池渗漏对地下水环境的影响,通过资料的收集、水文地质调查、现场钻探系列工作,构建了垃圾填埋场渗滤液收集池渗漏下的解析法模型,预测地下水环境影响的程度。研究结果显示,本次垃圾填埋场渗滤液收集池在发生渗漏后,COD_(Mn)365 d后其超标影响范围已经至严家沟,氨氮365 d后其超标影响范围也到了严家沟。为防治垃圾填埋场渗滤液收集池渗漏事故,对地下水环境造成影响,主管部门应从源头对污染源进行控制,在地下水流向上下游布设地下水监测井进行监控。

To predict the impact of the leakage pond leakage of the garbage filtage project of the garbage landfill project on the groundwater environment of the region,through data collection,hydrogeological survey,on-site hydrogeological survey work,the groundwater environment impact prediction method of the groundwater environment impact on the groundwater of the garbage landfills based on the analysis method is established.The results show that after the leakage of the COD_(Mn) of the osmotic collection pool of the garbage landfill,the scope of its excessive influence after 365 d has reached Yanjiagou,after the leakage of ammonia nitrogen,the scope of its excessive influence also reached Yanjiagou after 365 d.In order to prevent the leakage accident of the osmotic filtration fluid of the waste landfill and the impact on the groundwater environment,the competent department shall control the pollution source from the source and monitor the groundwater monitoring well in the underground water flow to upstream and downstream.
