摘要
调查了广州市垃圾转运站臭气中氨和硫化氢的含量和特点,分析了氨、硫化氢与现场臭味的相关性,结果表明:氨、硫化氢在垃圾站内臭气的含量分别集中在0.038～0.094、0.010～0.025mg/m3。氨的含量普遍明显低于其嗅觉阈值,与垃圾站现场臭味几乎无关;硫化氢则相反,其含量普遍高于其嗅觉阈值,含量范围对应其单一物质的臭气强度为2.0～2.5,且在垃圾站不同臭级区域的测定数据间存在极显著性差异(P<0.0001)。硫化氢与现场臭级存在一定的相关性,是垃圾站普遍存在的典型恶臭物质之一。
The content range and characteristics of ammonia and hydrogen sulfide in stench of Guangzhou waste transfer stations were investigated. And relativity of contents of ammonia and hydrogen sulfide and on-site stench was analyzed. The results showed that within waste station, the contents of ammonia and hydrogen sulfide were 0. 038～0. 094 mg/m3 and 0. 010～0. 025 mg/m3 respectively. The contents of ammonia were obviously lower than the sense of smell threshold value commonly, so ammonia almost has nothing to do with stench of waste station; while the contents of hydrogen sulfide, on the contrary, were higher than the sense of smell threshold value commonly, and the content range of single matter corresponded odor intensity between 2. 0 and 2. 5. And so on there’s extreme notable difference (P < 0. 000 1) in the testing data in different odor intensity areas of the waste station. There’s certain relativity between contents of hydrogen sulfide and on-site odor intensity. Hydrogen sulfide is one of the ubiquitous representative odor substances.
