| 中文摘要 |
| 采用国内现有微生物菌种挂膜接种的生物膜填料塔净化低浓度有机废气是可行的。初步实验研究结果表明,增加入口气体甲苯浓度和气体流量,同时减小循环液体喷淋量,可使甲苯的生化去除量增大,每L体积的生物膜填料对甲苯的生化去除量最大可达157.13mg/h.由实验结果推断,生物膜填料塔对废气中甲苯的净化去除过程属于传质控制过程。对比验证结果表明,本研究建立的动力学模式对实际过程有很好的适用性。 |
| 英文摘要 |
| From this study, a fact can be affirmed that in China,it is feasible to purify the waste gas containing organic compounds in low concentration by using the biological trickling filter with biofilm packing-material, inoculated with a mixed culture from a biostation of treating wastewater in a coke-oven plant.The results of preliminary experiment showed that with the increasing of the concentration of toluene in in fluent gas and gas flow, and decreasing of the flow of circulating liquid simultaneously,the biochemical elimination of toluene in waste gas can be increased, which can reach 157.13 mg per hour per litre packingmaterial with biofilm in the tower.From the experimental results,it can be inferred that the pro cess of purifying the waste gas containing toluene in low concentration by using the bio filter belongs to mass transfer.By contrast,a good suitability of the kinetic model established in this study for practical process is verified. |
