| Abstract: | The experiments of the removal of ammonia-nitrogen from landfill leachate by ultrasound irradiation were carried out. The studies indicate that the ultrasonic irradiation is an effective method for the degradation of ammonia-nitrogen from landfill leachate. The mechanism of ammonia-nitrogen removal by ultrasound irradiation may mainly be that the ammonia molecules in leachate enter into the cavitation bubbles and transform into nitrogen molecules and hydrogen molecules via pyrolysis under instant high temperature and high pressure in the cavitation bubbles. |
