【摘要】 垃圾渗滤液中富含多种毒害物质,特别是有机物污染物和重金属,未经妥善处置会对周边环境产生严重危害.为了对典型垃圾填埋场渗滤液的处置方法选择提供依据,作者对垃圾渗滤液中的有害成分进行了定性定量分析.实验中采用电感耦合等离子体质谱(ICP-MS)和气相色谱/质谱联用仪(GC-MS)对广东某典型垃圾填埋场渗滤液中的重金属、有机污染物等有害成分进行了分析,共测得47种主要有机污染物和42种重金属,其中多种重金属元素和有机污染物为优先控制污染物,铬和铅的质量浓度分别高达25.35μg/L和22.56μg/L,垃圾渗滤液处置方法的选择必须考虑这些毒害物质的危害.更多还原

【Abstract】 Landfill leachate,which contains rich amount of hazardous constituents,for example organic pollutants and heavy mentals,which would caused serious effect on the surrounding evnironment if it was unsuitable treated.In order to select suitable treatment method for leachate from a typical landfill in Guangdong province,hazardous constituents in the landfill leachate had been detected in the paper.The inductively coupled plasma-mass spectrometry method(ICP-MS) and gas chromatograph-mass spectrometer method(GC-MS) were used to measure the concentration of heavy metals and organic pollutants in the landfill leachate 47 kinds of organic pollutants and 42 kinds of heavy metals was detected in the leachate.Among them,many organic pollutants and heavy metals belonged to the list of environmental priority control pollutants,and Cr and Pb concentration was up to 25.35 μg/L and 22.56 μg/L,respectively.Based on the result above,the harm caused by these hazardous constituents should been considered carefully during the course of selecting handling method for the landfill leachate.更多还原
