摘要: Abstract In order to design treatment wetlands with maximal nitrogen removal and minimal nitrous oxide (N2O) emission, the effect of influent C/N ratios on N2O emission in surface flow constructed (SF CWs) for sewage plant effluent was investigated this study. The results showed that CWs were significantly affected by ratio influent. Much higher efficiency NH4+-N (98%) TN (90%) obtained simultaneously SF at 12:1, low (8.2 mg/m2/d) percentage N2O-N (1.44%) also observed. These study would be utilized determine how fluxes respond variations improve sustainability wastewater treatment.
