徐州岩溶地区生活垃圾填埋场地下水有机污染特征研究
|
摘要
为了探究徐州岩溶地区生活垃圾填埋场地下水有机污染特征,选择该地区最具代表的睢宁生活垃圾卫生填埋场(S)为研究对象,丰、平、枯3个水期对该填埋场地下水有机污染物进行监测分析;同时选取非岩溶地区雁群生活垃圾卫生填埋场(Y)地下水进行枯水期同期监测、对比分析。研究结果表明:S填埋场枯水期地下水有机污染物种类最多,除四氯化碳、邻苯二甲酸二正丁酯和邻苯二甲酸二(2-乙基己基)酯外,其它污染物枯水期含量均最高,且上述3种污染物丰水期含量最高,结合SVOCs的ρ_(地下水)/ρ_(渗滤液)值丰水期最大,说明降水容易携助有机污染物向地下水迁移。位于岩溶地区的S场地下水钛酸酯类总含量较高,其中邻苯二甲酸二异丁酯和邻苯二甲酸二正丁酯分别是非岩溶地区Y场地下水含量的14.7和3.9倍,说明垃圾填埋场钛酸酯类污染物更容易对岩溶地区地下水构成威胁。
In order to study the characteristics of groundwater organic pollution of landfill site in Xuzhou karst area. Suining landfill site were studied that is the most representative landfill in karst area. In this paper, the groundwater organic pollutants in Suining landfill were monitored and analyzed in wet, normal and dry season. At the same time, we monitored Yanqun landfill groundwater which in non-karst area for comparison in dry season. The results prove that: S landfill groundwater has the most organic pollutants and highest content of pollutant in dry season, except carbon tetrachloride, dibutyl phthalate and phthalic acid(2-ethyl hexyl) esters,which content are highest in wet season.We conjoint the ρ(groundwater)/ρ(leachate) of SVOCs was the greatest in wet season,it was indicated that precipitation is easy to carry organic pollutants to groundwater migration. It was found that the total content of titanate was higher in S landfill in karst area, which content of diisobutyl phthalate and dibutyl phthalate were 14.7 and 3.9 times of Y landfill in non-karst area. The organic pollution of titanate in landfill are more likely pose threat to groundwater in karst areas.
