Abstract

In this paper, the removal efficiency of NO_x by aerobic denitrifying bacteria in bio-filter and bio-trickling filter was described, respectively and the removal mechanism of NO_x was explored. The result showed that the bio-trickling filter was more proper than the bio-filter when dealing with NO_x. The new device-the combination of the bio-filter and bio-trickling filter was employed to test the application of aerobic denitrifying bacteria in the removal of NO_x. Effects of the inlet concentration of NO_x, empty bed residence time (EBRT) and liquid flow on the removal efficiency of NO_x were investigated in the new device. And the removal efficiency of NO_x up to 94.2 % was obtained at oxygen content of 13 %, inlet NO_x concentration of 1100 mg/m³, nutrient fluid flow of 15 L/h and empty bed residence time of 35 s.
