| 摘 要： | 通过生物滴滤塔(biotrickling filter,BTF)净化硫化氢(H2S)、四氢呋喃(THF)、二氯甲烷(DCM)混合废气,研究其挂膜启动和稳定运行条件下的降解性能.结果表明,混合废气H2S、THF、DCM浓度分别为200、100和100 mg·m-3,空床停留时间(empty bed retention time,EBRT)50～20 s的条件下,H2S和THF的去除率分别能够维持在99%和60%左右,而DCM的去除率随EBRT的缩短从90%逐渐降低至37%左右.利用Michaelis-Menten动力学模型分析得到,理论降解效果为H2S>THF>DCM. |

| Abstract: | A biotrickling filter (BTF) was designed for treating mixed waste gases, which contained hydrogen sulfide (H2S), tetrahydrofuran (THF) and dichloromethane (DCM) at the start-up and steady states. The removal efficiency of H2S and DCM could maintain about 99% and 60%, respectively, and the removal efficiency of DCM was reduced from 90% to 37% with the shortening empty bed retention time (EBRT) form 50 to 20 seconds when the inlet concentrations were 200, 100, 100 mg·m-3 of H2S, THF, DCM, respectively. In the theoretical study, the biodegradation efficiency of contaminants was H2S>THF>DCM by analyzing the Michaelis-Menten Dynamic model. |
