%X An optimized aerobic denitrifying bacteria was applied to a biofilter for the removal of NOx. The removal process of NOx was investigated, and the relationship between environmental factors and NOx removal efficiency as well as the NOx transfermechanism under aerobic conditions are discussed. The results show that the biofilter finished start-up after 26 days and the presence of oxygen has no evident negative effect on the efficiency of NOx removal. Mainly happening at the middle and under part of the biofiltration system, the removal of NOx get a high efficiency of 93.6% at the EBRT of 59s and the inlet NOxconcentration of 286.4 mg/m3 with 10% O2. A special biomembrane system was formulated by nitrobacteria, facultative denitrifying bacteria and aerobic denitrifying bacteria in the biofiltration system.
