摘　　要：[目的]研究土地处理工艺对再生水的脱氮效果。[方法]利用土地处理系统,对水质为一级A标准的再生水进行深度处理,考察出水脱氮效果。[结果]土壤介质中的有机质含量与脱氮效果具有正相关关系。选择合适的土壤介质,TN和NH3-N具有很好的去除效果,分别可以达到90%和75%左右。采用土地处理工艺对再生水进行处理,进水中90%以上的TN在距土壤介质表面30 cm以内被去除,75%左右的NH3-N在距土壤介质表面10 cm以内被去除。[结论]该研究为土地处理系统应用于再生水的脱氮提供了理论依据。[ 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 media and nitrogen removal effect. With appropriate soil media, TN and NH3-N could obtain the removal efficiency of more than 90% and 75% respectively, and they could be removed in 30 cm and 10 cm height of soil media respectively with land treatment system to treat reclaimed water. [ Conclusion] The research provided theoretical basis for application of the land treatment system into nitrogen removal of the reclaimed water.
