[Objective]The research aimed to study nitrogen removal effect of the land treatment process on reclaimed water. [Method]By using land treatment system,reclaimed water which reached one-level A standard was conducted advanced processing,and nitrogen removal efficiency of the effluent was inspected. [Result] There was a positive correlation between organic matter content of the soil medium and nitrogen removal effect. With appropriate soil medium,TN and NH3-N could obtain the removal efficiency of more than 90% and 75% respectively,and they could be removed at 30 and 10 cm height of soil medium respectively with land treatment system to treat reclaimed water. [Conclusion]The research provid-ed theoretical basis for application of the land treatment system into nitrogen removal of the reclaimed water.
