| Abstract: | The mechanism of denitrification by constructed wetland is introduced which include the absorption by the hydrophyte and nitration and denitrification by the microorganism and volatilization of ammonia and ammonification and iron exchange. The factors impacting the denitrification rate are discussed. The present status of the technology in China and foreign countries are analyzed. |
