| 摘 要： | 提出了采用可产臭氧的高强球形紫外灯光解氧化硫化氢气体。考察了硫化氢初始浓度、湿度、含氧量、停留时间对硫化氢去除效率的影响。实验结果表明，硫化氢浓度在低浓度范围内，对硫化氢的去除效率可以达到99％以上。反应体系内气体湿度比含氧量对硫化氢的去除效率的影响更明显。气体湿度控制在45％～60％和反应停留时间控制在6～10s范围内为最佳。高强紫外球形灯处理硫化氢过程分别存在直接光解和臭氧氧化作用及两者的协同作用。 |

| Abstract: | A photolysis and oxidation method using high-intensity UV spherical lamp for removal of H2S gas was proposed. The effects of initial concentration of H2S, humidity, oxygen ratio, retention time on the removal of H2S were investigated. Under low H2S concetration levels, the removal of H2S was up to 99%. In the reaction system, humidity had greater effect on H2S removal than oxygen content. The optimum ranges of humidity and retention time were 45%~60% and 6~10 s, respectively. In the H2S removal process, the UV lamp could directly photolyze and oxidize H2S, and the two reactions had synergistic effects. |
| Keywords: | high-intensity UV spherical lamp hydrogen sulfide deodorization photolysis oxidation |
