Artificial aeration is considered to be a promising approach to improve pollutants removal efficiency of constructed wetland(CW).This study designed a novel aerated CW using exhaust gas from biological wastewater treatment through coupling sequencing batch reactor(SBR)and vertical flow constructed wetlands(VFCWs).Compared with un-aerated CW,the introduction of exhaust gas into VFCW improved NH4+-N,TN and COD removal efficiency by 56.23%,37.14%and 20.62%,respectively.Aeration also enhanced the growth of plants in CWs,however,no significant difference was observed in plant growth between VFCW aerated with air and exhaust gas.Furthermore,the exhaust gas ingredients including odors(H2S,NH3),greenhouse gas(mainly N2O)and microbe aerosol were remarkably reduced after passing through CW.The removal efficiencies of H2S,NH3 and N2O were 36.68%,77.78%and 52.17%,respectively.Microbial analysis results revealed that CW with exhaust gas had the highest microbial community richness of ammonia-oxidizing bacteria(AOB)and nitrite-oxidizing bacteria(NOB),which optimized nitrogen transformation processes in CW.These results suggest that intermittent aerated CW with exhaust gas might have certain potential application for purifying the wastewater treatment plant effluent,however,further full-scale investigation is needed.
