【摘要】 采用预浓缩、气相色谱-质谱联用及脉冲火焰光度检测的方法对石化污水处理场排放的废气污染物进行了定性与定量分析,并采用相应的污染物排放标准及其人体感知嗅阈值进行了污染程度评价。结果表明,污水处理场在各个采样点位均有挥发性有机污染物和恶臭污染物检出,其中以污水进口最为严重。从检出物的浓度水平而言,苯系物和恶臭污染物均存在超标现象,而且检出的恶臭污染物浓度水平远高于人体感知嗅阈值。

【Abstract】 Using preconcentration,GC/MS and GC/PFPD method,the qualitative and quantitative analysis on the exhausted gases have been developed,which came from a wastewater treatment system of a typical petrochemical refinery.The related emission standards and human odor value have been used to evaluate the contamination level.The results showed,the volatile organic pollutants and odor pollutants have been detected at all sampling sites,and the severest contaminated site was the wastewater import.As the concentration level of the detected pollutants,there were exceeding standards compounds both in BTEXs and odor pollutants,and most of odor pollutants were much higher than the human odor value.
