| 中文摘要 |
| 采用低温等离子体-生物法处理硫化氢恶臭气体，硫化氢的去除效率比单独等离子体提高83.4%~90.1%，而且可消除等离子体氧化硫化氢产生的二氧化硫等二次污染物，将其转化为硫酸根和水.采用PCR-DGGE技术研究低温等离子体臭氧对处理硫化氢恶臭气体的生物滴滤塔内微生物群落结构变化规律.结果表明，低温等离子体臭氧影响生物滴滤塔内微生物群落结构，会导致一部分菌群消失，同时产生一些新的菌群；塔内微生物由8个菌种变为9个菌种，3个脱硫作用的硫杆菌菌群消失，出现4个分别具有脱硫作用和嗜酸性的新菌种，5个分别具有脱硫和硫酸盐还原菌种不变.低温等离子体-生物法系统生物滴滤塔内主要有硫杆菌属（Uncultured Thiobacillus sp.，Acidithiobacillus thiooxidans strain dfI，Uncultured Thiobacillus sp.，Uncultured Acidiphilium sp.），黄单胞菌属（Uncultured Xanthomonadaceae bacterium clone SBLE6C12），δ-变形菌（Uncultured δ-Proteobacterium）及副球菌属（Paracraurococcus sp. 1PNM-27）. |
| 英文摘要 |
| A bench scale system integrating a non-thermal plasma (NTP) unit with a biotricking filtration (BTF) unit for the treatment of gases containing hydrogen sulfide (H2S) was investigated. The additional use of the biotrickling filter to NTP reactor not only leads to the enhancement of hydrogen sulfide removal efficiency up from 83.4% to 90.1%, but also eliminates gas-phase intermediate products from NTP degradation of H2S to produce sulfate and H2 O. The dynamic changes of microbial community in BTF influenced by ozone from NTP were assessed by PCR-DGGE. Results show that the microbial community was affected by ozone. After the integration, a part of microorganisms disappeared, and meanwhile some new microorganisms appeared. The microbial community structure in BTF changed from eight bands to nine bands; three bands which have the functions of desulfurization disappeared and four bands which have the functions of desulfurization appeared; five bands which have the functions of desulfurization and sulfate reduction were unchanged. The bacterial groups in the BTF unit of NTP-BTF system include Uncultured Thiobacillus sp.,Acidithiobacillus thiooxidans strain dfI,Uncultured Thiobacillus sp.,Uncultured Acidiphilium sp., Uncultured Xanthomonadaceae bacterium clone SBLE6C12, Uncultured δ-Proteobacterium and Paracraurococcus sp. 1PNM-27. |
