摘要

为了解垃圾填埋场地下水环境污染状况,更好地开展地下水污染防治工作,以深圳市某正规生活垃圾填埋场为例,在资料收集和水样采集检测的基础上,采用单指标评价法对填埋场地下水水质进行评价。评价发现,填埋场地下水水质现状为Ⅴ类,水质均存在不同程度污染。通过对比地下水水质与渗入垃圾渗滤液的地下水导排口水质数据,发现地下水中主要超标指标有浑浊度、砷、铁、锰、挥发性酚类、氨氮、总大肠菌群、耗氧量等,浑浊度、砷、铁、锰超标为外环境影响所致或环境本底值高,挥发性酚类、氨氮、总大肠菌群、耗氧量指标超标主要由垃圾渗滤液泄漏所致。
        In order to understand the environmental pollution status of groundwater in landfills,and better carry out groundwater pollution prevention and control work,this paper takes a formal domestic waste landfill in Shenzhen city as an example. Based on the data collection and water sample collection and testing,the single-index evaluation method is used to evaluate the groundwater quality of the landfill. The evaluation found that the groundwater quality present situation in the landfill is level V,and there are varying degrees of water pollution. Comparing the water quality of groundwater with the water quality data of the drainage outlet infiltrating the landfill leachate,it is found that the main indicators exceeding standards in the groundwater are turbidity,arsenic,iron,manganese,volatile phenols,ammonia nitrogen,total coliforms,and oxygen consumption. Among them,turbidity,arsenic,iron and manganese exceeded the standard caused by external environmental impact or high environmental background value,while the volatile phenols,ammonia nitrogen,total coliforms and oxygen consumption exceeded the standard mainly caused by leakage of landfill leachate.
