【摘要】 基于对大连市城市生活垃圾填埋场垃圾渗滤液处理处置必要性和紧迫性的分析,及对垃圾渗滤液环境污染机理的探讨,分别采取大连市城市生活垃圾填埋场新产和存储老化垃圾渗滤液进行分析测试,并运用单项污染指数法进行水质评价.评价结果表明,大连市城市生活垃圾填埋场垃圾渗滤液污染物浓度超标严重,其中重金属污染物浓度极高.在分析垃圾渗滤液水质特征的基础上,对大连市城市生活垃圾填埋场垃圾渗滤液的处理处置提出了意见和建议.更多还原

【Abstract】 Both based on the necessity and impendence situation for the treatment of landfill leachate in Dalian municipal were analyzed,and the environment pollution mechanism of landfill leachate was studied.The landfill leachate that were both in storage ponds and the new production were sampled and tested.The water quality of landfill leachate was assessed with the method of single pollution index.The results showed that the water quality of landfill leachate of Dalian municipal landfill is quite worse,especially in the heavy metal pollution.Finally,characters of landfill leachate of Dalian municipal landfill were summarized,and suggestions on the treatment of landfill leachate were proposed.更多还原
