摘要本文研究了实验室规模的生物滴滤塔和三相气升式生物反应器从废气中去除二氯甲烷（或二氯甲烷）蒸气，并将研究结果用于小型工业规模反应器的设计。选择用于按比例放大的条件是100 m3 h-1的空气流速、2 g m-3的二氯甲烷入口浓度和99.5%的目标去除率。放大程序，设计和成本分析进行了讨论。全尺寸生物滴滤器似乎是最具成本效益的反应器，每处理1 000立方米的全球成本约为62美元。气升式反应器中的处理估计是昂贵的两倍，催化氧化昂贵的5倍。生物废气处理为传统的废气处理技术提供了经济的替代方案。
Abstract Laboratory scale biological trickling filters and three-phase airlift bioreactors have been studied for the elimination of methylene chloride (or dichloromethane) vapors from waste air, and the results used herein for the design of small industrial-scale reactors. The conditions chosen for scale-up were an air flow rate of 100 m3 h-1, a methylene chloride inlet concentration of 2 g m-3, and a target removal of 99.5%. The scale-up procedure, design, and cost analysis are discussed. The full-scale biotrickling filter appears to be the most cost-effective reactor, with global costs of about $62 per 1,000 m3 treated. Treatment in the airlift reactor was estimated to be twice as expensive and catalytic oxidation 5 times as expensive. Biological waste air treatment offers economical alternatives to conventional techniques for waste air treatment.
