| 摘 要： | 介绍了恶臭强度的6级分类法,针对含硫气田典型的5种含硫恶臭化合物,利用韦伯-费希纳公式研究了气体浓度和恶臭强度的关系,计算并分析了我国环境标准和职业卫生标准规定的阈限值对应的恶臭强度。GB/T14554—1993《恶臭污染物排放标准》规定一级厂界浓度标准限值对应的恶臭强度为2.5左右,二级新改扩建厂界标准限值对应恶臭强度为2.8左右。我国国家职业卫生标准GBZ 2.1—2007中规定的含硫恶臭气体职业接触限值对应的恶臭强度均在4以上。

Relationship between odor threshold limit value and odor intensity in sour gas fields |
| |
| Abstract: | The 6-level classification method of odor intensity was introduced. Focusing on the 5 typical odor sulfides in sour gas fields,the relationship between gas concentration and odor intensity was studied using the Weber-Fechner’s formula,and the odor intensities corresponding to the threshold limit value provided in Chinese environmental standards and occupational health standards were calculated. The calculation results show that:According to the national emission standard of GB/T 14554-1993,the odor intensities corresponding to the first-and second-grade limits of gas concentration in factory boundary are about 2.5 and 2.8 respectively;According to the national occupational health standard of GBZ 2.1-2007,the odor intensity corresponding to the occupational exposure limits of odor sulfides are all above 4. |
