张落坪垃圾填埋场对地下水污染的评价

Assessment to groundwater pollution in Zhangluoping landfill site

应用综合污染指数或内梅罗污染指数对张落坪垃圾填埋场附近的地下水进行污染程度评价,受东沙坡村中非卫生填埋垃圾坝的影响,垃圾坝下游地下水污染严重,污染因子依次是NO2-N、NH+、NO3-N和Cl-,同时由于垃圾填埋场在建场之初的防渗设施防渗效果不理想,导致垃圾填埋场下游地下水有一定程度的污染。

The comprehensive pollution index and Nemerow pollution index are applied to assess the groundwater pollution around the Zhangluoping Landfill site.Influenced by the unsanitary landfill site in Dongshapo village,the groundwater at the lower reaches is seriously polluted.The pollution factors are NO2-N,NH＋,NO3-N and Cl-in turn.Meanwhile,due to the imperfect anti-seepage effect resulted from the impervious facilities at the beginning stage in setting up the landfill site,the groundwater at the lower reaches of the landfill has been polluted to a certain degree.
