摘要
介绍了广州市部分垃圾转运站臭气分析实验结果,发现国家标准GB14554—1993规定的恶臭指标的数据变异程度较大,单项污染物指标的测定值大多远低于标准限值,综合指标臭气浓度普遍超标,2类指标结果不一致;臭气样品的色谱质谱全扫描分析结果表明:垃圾恶臭污染物主要来自卤代烃和苯系物,另外可能还包括含量低、嗅觉阈值低的有机硫类化合物等。
Test analysis results of odor in some waste transfer stations of Guangzhou were introduced based on national standard GB 14554—1993, which provided a proof about inconsistency between odor concentration and other odor targets. Most odor targets were below the limited value of standard, odor concentration was commom over and above the standard. Odor samples were detected by GC-MS full scanning. The results showed that odor pollutants were mainly from hydrocarbon chloride and homo-benzenes, and probably including some other sulfur organic compounds usually with lower concentration.
