| 摘 要： | 采用二次热解析-气相色谱/质谱仪(GC/MS)与电子鼻对广州市某典型城市污水处理厂排放的挥发性恶臭有机物(MVOCs)进行检测与分析,结果表明:①芳香烃是该污水处理厂排放的最普遍、浓度最高的挥发性恶臭有机物质,浓度范围为96.61～818.03μg.m-3,均占各处理单元总MVOCs含量的50%以上,远高于其他MVOCs物种.②城市污水厂的挥发性芳香烃主要来源于生活污水,而污泥处理过程是污水处理厂释放这些污染物的重要环节,各单元排放的芳香烃化合物总浓度由高至低表现为:污泥脱水机房>污泥浓缩池>曝气池>格栅>生化池>沉砂池.③主成分分析(PCA)能够区分各单元排放的废气气味特征,识别指数达到71%,而按照各处理单元挥发性芳香烃的组成水平配制的模拟气体,其PCA识别指数高达94%,反映了不同处理单元挥发性芳香烃的气味也有很大不同.④将T70/2传感器所测得的实际气体与模拟气体的气味指纹进行比较,实际气体的气味指纹要大于模拟气体,从相关性方面分析得知挥发性芳香烃的气味指纹与各单元的气味指纹均呈现较好的正相关,其中曝气池挥发性芳香烃的气味指纹与实际气体气味指纹相关性尤为显著,达到0.98.
