  • 摘要: 利用反硝化的方法处理吡啶气体，并通过与普通生物洗涤塔对吡啶废气处理效果的对比研究，探索了难降解VOC-吡啶废气反硝化净化过程的几个问题。实验设置实验组（1#反应器）和对照组（2#反应器），结果表明，1#对吡啶废气的去除能力更大，最大去除负荷为84.5 mg·（L·h）-1，而2#最大去除负荷为49.2 mg·（L·h）-1。1#系统中反硝化作用对净化吡啶的贡献率，在一定范围内，随着进气浓度的增大而增大。当进气浓度从250 mg·m-3增大到1 000 mg·m-3，反硝化去除负荷从8.0 mg·（L·h）-1增加到62.8 mg·（L·h）-1，在总去除负荷中所占比重从32.5%增加到73.6%，随着进气负荷的增加，反硝化逐渐起主要作用。
    Abstract: Anoxic denitrification was used to treat pyridine waste gas.Several questions were studied by comparing the removal efficiencies between a traditional bio-trickling filter and the reactor adapted in the experiment.An experimental group(1#) and a control group(2#) were set up. The results showed that 1# system had a bigger removal capacity.The biggest removal loads in 1# and 2# system were 84.5 mg·(L·h)-1 and 49.2 mg·(L·h)-1 respectively.Denitrification's contribution to the removal of pyridine waste gas increased along with the increase of inlet concentrations. As inlet concentration increased from 250 mg·m-3 to 1 000 mg·m-3, the removal load by denitrification increased from 8 mg·(L·h)-1 to 62 mg·(L·h)-1 and the proportion in total removal by denitrification increased from 32% to 73%.Denitrification played a leading role gradually in treating refractory VOC as the inlet load increased.
