  • 摘要: 采用自行研制的生物转鼓反应器（RDB）处理难溶于水的NO废气，为提高NO的传质系数和去除效率，实验考察了营养液中添加FeII (EDTA)络合剂协同RDB以提高NO去除效率的过程。结果表明，当空床停留时间（EBRT）为0.96 min时，在营养液中添加FeII (EDTA)至100 mg/L后，NO的去除效率从70.78%升至79.26%。未添加FeII (EDTA)时NO去除率随营养液的增加下降，添加FeII (EDTA)至100 mg/L后，去除率随营养液量的增加先上升后下降，且下降速率比上升速率大。随着营养液中FeII (EDTA)浓度从0增加至500 mg/L，实验最佳温度从32.5℃升至47.5℃，但添加FeII (EDTA)至100 mg/L对实验的最适pH值没有太大影响。
    Abstract: A novel process for the removal of NO by a combined FeII (EDTA) absorption and microbial reduction in a rotating drum biofilter(RDB) was demonstrated. FeII (EDTA) was added in the nutrient solution to improve the mass transfer efficiency of NO from the gas to the liquid. The results showed that under the experimental conditions of empty bed residence time of 0.96 min, the NO removal efficiency was improved from 70.78% to 79.26% after the addition of FeII (EDTA) to 100 mg/L in the nutrient solution. Without the FeII (EDTA) addition, the NO removal efficiency decreased with the increasing of the amount of the nutrient solution.But it increased at the beginning of the FeII (EDTA) addition and then decreased with the addition of FeII (EDTA) to 100 mg/L. The most suitable temperature increased from 32.5℃ to 47.5℃ when FeII (EDTA) increased from 0 mg/L to 500 mg/L. There was little change of the pH with the addition of FeII (EDTA) to 100 mg/L.
