城市垃圾渗沥液引起地下水氮污染的研究

Nitrogen Contamination of Groundwater Originated from Urban Landfill Leachate

通过对垃圾堆放场地下水氮污染状况的监测 ,分析了垃圾渗沥液的水质特征及其对地下水的氮污染影响。结果表明 ,垃圾渗沥液含有高浓度的氨态氮 ,对垃圾场还原性地下水的氮污染主要以 NH+4 -N污染为主。垃圾场地下水氮污染浓度变化与渗沥液数量。

Nitrogen contamination of landfill on groundwater has been monitored and evaluated by an analysis of characteristics of landfill leachate and an assessment of the potential effects of nitrogen contamination on groundwater. The results showed that there were large amounts of ammonia-nitrogen in landfill leachate and the contamination of ammonia-nitrogen was the major form of pollution in groundwater of landfill. It has been also found that nitrogen contamination of groundwater was correlated well with the amounts and concentrations of ammonia in landfill leachate.
