矿化垃圾处理渗滤液中有机污染物的GC-MS研究

以上海市老港填埋场中矿化垃圾反应床处理渗滤液为例,定性分析了该反应床进水和出水中有机污染物组分,同时半定量分析了该反应床对有机污染物的去除效果,分析结果显示:从宏观尺度上,矿化垃圾反应床很好的去除了渗滤液中的污染物质,渗滤液经过矿化垃圾反应床后,14种有机污染物得到完全去除,3种有机物的含量降低,产生1种新物质,邻苯二甲酸二辛酯在进水和出水中同时存在,从谱图上可以看出其出水浓度降低,在不同pH值萃取条件下,从进、出水谱图的对比中可以发现,进水中大部分有机污染物得到去除。

Analysis of Organic Pollutants Removal from Leachate after the Aged-refuse Biofilter in Laogang landfill by GC-MS

This paper is based on the leachate treatment by aged-refuse biofilter located in Shanghai Laogang landfill,qualitatively analyzing the organic pollutants of both influent and effluent and half-quantitatively analyzing the removal effect of organic pollutants by aged-refuse biofilter.The results show that leachate pollutants are removed in a large quantity from macroscopic concept.After the treatment of aged-refuse biofilter,fourteen organic pollutants in the leachate are removed completely,the content of three organic pollutants decreases and one new organic pollutant produces.Bis(2-ethylhexyl) phthalate is detected both in the influent and effluent and its concentration decreases in effluent.It can be seen from the contrast of influent and effluent spectrogram,most of the organic pollutants in the influent are removed under extraction conditions with different pH values.
