【摘要】通过研究沸石床复合垂直流人工湿地中不同形态氮的空间变化,分析了其脱氮机理,认为沸石对NH₃—N的吸附作用是脱氮的重要途径,硝化和反硝化作用提高了TN的去除率,硝化和反硝化强度影响到沸石的饱和周期和生物再生,有待进一步研究。更多还原

【Abstract】 The presented study investigated the spatial variation of different forms of nitrogen in zeolite integrated vertical-flow constructed wetlands,analyzed the mechanism for the removal of ni- trogen.It was concluded that zeolite adsorption of nitrogen is an important approach for nitrogen removal.Also,nitrification and denitrification improve the TN removal.Further study concerning the influence of the intensity of nitrification and denitrification to the saturation cycle and zeolite bio- regeneration would be valuable.更多还原
