Abstract:
To improve the simultaneously removal efficiency of SO2 and NOx from flue gas by the artificial compound functional bacteria in the biofilm-packing tower,the effects of inlet concentration of SO2 and NOx in influent gas,gas flow and circulated liquid flow were studied.The results indicated that with 1500—3000mg/m3 SO2,1400—1600mg/m3 NOx,0.2m3/h gas flow and 9.0L/h circulated liquid flow,the NOx removal rate was improved by 17.22% higher than before (44.81%),reaching 62.03%,meanwhile SO2 removal rate was 100% as before.
