| 摘 要： | 采用调查和多种检测方法对有组织排放的空气恶臭的物质进行定性分析和定量监测,以证实和确认污染源。在走访受害居民和工业污染源调查的基础上,使用三点比较式嗅袋法、分光光度法、主动式吸附管热解析/GC/MS和不锈钢采样罐/GC/MS法检测空气恶臭的物质的种类和含量,并且通过自动监测仪器长期定点观测污染发生时和消除污染源后空气恶臭的物质含量的变化。结果表明,导致空气恶臭的物质为H2S和CS2,其中CS2为污染源的特征物质,相同时间和地点空气中H2S和CS2的质量浓度相关系数为0.84;污染源下风向空气中H2S含量高,年平均值为0.084mg/m3;不在下风向的空气H2S含量低;清除污染源后其下风向空气中H2S年平均值为0.008 mg/m3,空气不再恶臭。该排查方法为监控有组织排放恶臭的污染源提供了经验和实例。

| Abstract: | Investigation and detective methods were used to qualitatively analyze and quantitatively monitor the stink substances emitted intentionally for identification of the pollution source.Based on investigation of the industrial pollution and the residents concerned,the stink substances and their contents in atmosphere were determined by Triangle Odor Bag method,spectrophotometry,Active Sampling onto Sorbent Tubes-GC/MS and Stainless Steel Canister-GC/MS.The results showed that H2S and CS2 caused the bad smell,... |
