摘要：

In this paper, the removal efficiency of NOx by aerobic nitrification bacteria and aerobic denitrification bacteria in bio-filter(BF) and bio-trickling filter(BTF) are described, and removal mechanism of NOx is explored. The results show that the aerobic denitrification bacteria is better than aerobic nitrification bacteria when dealing with NOx; and the BTF is more proper than the BF. The new device-the combination of the BF and BTF was used to determine the removal efficiency of NOx when oxygen content was 13%, the inlet NOx concentration was 1100 mg/m3, empty bed retention time (EBRT) was 35s, the removal efficiency of NOx was up to 94.2%.
