沈阳市垃圾填埋场周边水环境污染状况研究

Research on Pollution Situation of Water Environment near Landfill in Shenyang

[目的]研究沈阳市垃圾渗滤液对垃圾填埋场周边水环境的污染状况。[方法]以大辛垃圾填埋场为研究对象,在其周边布设采样点,检测水环境污染状况并进行地下水与地表水的评价。[结果]生活垃圾填埋场的地下水和地表水已经受到垃圾渗滤液的污染,垃圾填埋场地下水属于超Ⅳ类地下水,主要污染物为氨氮和挥发酚;垃圾填埋场附近地表水体九龙河属于劣Ⅴ类水体,主要污染物质包括有机物、磷、氨氮及粪大肠菌群。[结论]垃圾渗滤液对周边水环境存在污染,需要进行有效控制。

[ Objective ] The research aimed to study the pollution of water environment by landfill leachate near landfill in Shenyang City. [ Method ] Takeh Daxin landfill as object, the sampling sites around it were set. Then the pollution situation of water environment was investigated and the quality of groundwater and surface-water was evaluated. [ Result ] The results showed that the groundwater and surface-water in or near landfill were polluted through landfill leachate. Groundwater under landfill belonged to the standard under level four. The main pollutants were ammonia nitrogen and volatile phenols. Surface-water near landfill, which named Jiulong River, belonged to the standard under level five, and the main pollutants included organic matters, total phosphorus, ammonia nitrogen and fecal coliform. [ Conclusion ] The landfill leachate had negative influences on the water environment near landfill, which was urgent to be controlled effectively.
