| 摘 要： | 采用生物滤床处理NO模拟废气,研究了停留时间(EBRT)、有机物浓度等在生物硝化去除NO技术中的作用过程.实验结果表明,EBRT和有机物含量是影响NO硝化去除效率的主要因素,NO去除效果随着有机物含量和EBRT的增大而提高;当进口浓度50 mg/m3,营养液中葡萄糖40 mg/L,EBRT＞3 min时,NO去除率达95%以上.比较自养菌和异养菌对NO硝化去除的效果,异养菌的去除效率提高20%～30%,具有广泛应用前景.

| Abstract: | An investigation of the basis of the improved biofilter performance was carried out through the experiments, which were performed as a batch microcosm study to determine the enhancement of NO oxidation with the addition of organic substrates, and to determine the role of the organic matter in improving NO oxidation. The experiments compared gas-phase NO removal by a biofilter column seeded with autotrophic/heterotrophic organisms. The effect of empty bed residence time (EBRT) on the removal efficiency was investigated. At high glucose loadings, the mixed culture column demonstrated a remarkable increase in biotic removal of NO, about 95% in a 3-minute EBRT. |
