| 摘 要： | 利用甲硫醚(DMS)降解菌Alcaligenes sp.SY1和丙硫醇(PT)降解菌Pseudomonas putida.S-1强化生物滴滤塔(BTF)处理DMS和PT的混合废气,研究了其挂膜启动及稳定运行阶段的降解性能,并考察了该系统同时去除H2S的能力.结果表明,BTF在DMS和PT进口浓度均为50 mg·m-3,EBRT为30 s的条件下,运行11 d即可完成挂膜启动,填料上的生物量明显增加,DMS、PT的去除率分别可达到90%和100%.系统稳定运行时,DMS和PT的最大去除负荷分别为8.7 g·(m~3·h)~(-1)和12.4 g·(m~3·h)~(-1),PT的去除效果更佳.DMS和PT混合废气在降解过程中,PT对DMS的降解有较明显的抑制作用,当PT进气浓度大于51 mg·m-3时,DMS的去除效率下降.BTF还能同时有效去除H2S,当混合废气中H2S浓度达到230 mg·m-3时,H2S去除率仍能高达98%,但是115 mg·m-3以上的H2S会对DMS的降解产生不利影响.

| Abstract: | The biodegradation of gas-phase mixtrue of dimethyl sulfide (DMS) and 1-propanethiol (PT) was examined in a biotrickling filter (BTF), inoculated with a microbial consortium composed of activated sewage sludge, and pure strains of Alcaligenes sp. SY1 and Pseudomonas putida. S-1. BTF could be successfully started up within only 11 days when the inlet concentrations of DMS and PT were both 50 mg·m-3 and EBRT was 30 s, with 90% removal efficiency (RE) of DMS and 100% RE of PT. In the steady state, the maximum elimination capacities of DMS and PT were 8.7 g·(m3·h)-1 and 12.4 g·(m3·h)-1, respectively. The presence of PT with a concentration up to 51 mg·m-3 showed an antagonistic removal pattern for DMS, but the opposite did not occur. Meanwhile, the BTF showed high efficiency in the biodegradation of H2S. When the concentration of H2S was as high as 230 mg·m-3, the RE of H2S could reach 98%. However, H2S showed a declining effect on the removal of DMS when the concentration exceeded 115 mg·m-3. |
