北京市垃圾填埋场地下水水质自动监测特征指标筛选

Screen on Characteristic Index of Groundwater Quality Automatic Monitoring in Solid Garbage Landfill Site of Beijing

为筛选北京市垃圾填埋场地下水水质自动监测的特征指标,对垃圾填埋场地下水水质的监测数据进行了因子分析,并与垃圾填埋场渗滤液成分进行了对比研究。得到结论:北京市垃圾填埋场新建大口径监测井地下水水质自动监测可选择垃圾填埋场地下水污染特征指标为:总硬度、氯化物、氨氮、硝酸盐氮、锰和铁,而对于原有的监测井建议选择特征指标为:氯化物、氨氮、硝酸盐氮。

To screen the characteristic index of groundwater quality automatic monitoring in solid garbage landfill site of Beijing, the data of chemical component of groundwater samples was analyzed for factors, and it was contrasted and studied with the data of chemical component of the leachate. The conclusions are obtained that the characteristic index of groundwater quality automatic monitoring in solid garbage landfill site of new largediameter monitoring wells in Beijing are total hardness, chloride, ammonia nitrogen, nitrate nitrogen, manganese and iron, but those in the groundwater quality automatic monitoring of existing monitoring wells are chlo ride, ammonia nitrogen, nitrate nitrogen.
