| 摘 要： | 根据工业园区中TVOC和恶臭可能存在的主要气体组分,筛选传感器阵列,构建用于检测工业园区内TVOC和恶臭的电子鼻系统.本研究设计了TVOC污染指数（TPI）和恶臭污染指数（OPI）及基于电子鼻的现场检测方法.在此基础上,结合嘉兴市乍浦港区内化工园区污染情况分析,选择6个检测点进行现场检测,各传感器响应值经PCA分析,提取了2个主成分即可将8个传感器分为2类：TVOC型（S1）和恶臭型（S2～S8）.将现场采集的气体样品用GC/MS进行定性分析,各采样点TVOC物质积分面积百分比在10%以上的累积起来大多都占总面积的90%以上,而恶臭类物质则大多都在10%以下.结果表明：①选用合适的传感器阵列,结合PCA分析,可以初步反映工业园区内TVOC和恶臭的污染情况;②结合电子鼻测得的污染指数与GC/MS定性分析结果,可以大体得出工业园区TVOC和恶臭总体污染情况及各种污染物分布情况;③电子鼻和GIS技术综合应用到工业园区TVOC和恶臭的检测,能初步用于评估工业园区空间污染情况. |
