| Abstract: | Simultaneous
removal of NOx and SO2 from exhausted gas were
investigated by studying co-culture of sulfate reducing bacteria and anaerobic
denitrifying bacteria, separated from landfill leachate. When H2S, generated
by sulfate reducing bacteria was chosen as the sole electron donor for anaerobic
denitrifying bacteria, the co-culture system demonstrated a faster NO removal
rate, higher stability and better permanence. When the feed gas flow rates of N2
and SO2 were maintained constant at 0.1 m3/h and 16 ml/min respectively, the maximum
NO-removal rate could be achieved at over 92% with NO feed gas kept between 2-6
ml/min, while the SO2 removal rate was always above 95%. Long-term continuous
removal of NO exhibited an evident periodicity of five days, however, the fluctuation
range of NO-removal was decreasing. Moreover, the decrease of the gas flow rate
and the increase in NO
inlet concentration could contribute to a higher NO-removal rate |
