The removal of cyclohexane from gaseous emissions was studied using a biotrickling filter packed with polyurethane foam. Acivodorax sp. CHX100 was chosen as inoculum due to its ability to use cyclohexane as carbon source. Performance was evaluated by means of different resident times from 18 s to 37 s and concentration levels of 60, 90, 120, 160, 320, 480 and 720 mg C m, respectively. Removal efficiencies of 80%-99% and elimination capacities in the range of 5.4 g C m h-38 g C m h were achieved for concentrations among 60 mg C m-480 mg C m. The removal efficiency decreased to 40% at concentrations of cyclohexane of 720 mg C m. The dynamics of the microbial population showed the strain CHX100 as predominant during the different operational process of biotrickling filter. The results of this study propose a novel approach for cleaning waste air containing cyclohexane by means of a biotrickling filter.
使用填充聚氨酯泡沫的生物滴滤池研究了从气态排放物中去除环己烷的方法。由于Acivodorax sp. CHX100能够将环己烷用作碳源，因此选择其作为接种物。通过分别在18秒至37秒的不同停留时间以及60、90、120、160、320、480和720毫克碳/立方米的浓度水平下评估性能。对于60毫克碳/立方米至480毫克碳/立方米的浓度，去除效率达到80%-99%，消除能力在5.4克碳/立方米·小时至38克碳/立方米·小时范围内。在环己烷浓度为720毫克碳/立方米时，去除效率降至40%。微生物种群动态表明，在生物滴滤池的不同运行过程中，CHX100菌株占主导地位。本研究结果提出了一种通过生物滴滤池净化含环己烷废气的新方法。
