| 摘 要： | 以山东省平阴中水湿地为研究对象,通过对湿地水体、底泥的氨态氮(NH3-N)、硝态氮(NO3--N)沿程变化的分析,研究湿地对中水中氮(N)的去除效果。结果表明:湿地对水体中NH3-N的去除效果较好,而作为水体中N主要存在形式的NO3--N沿水流方向却呈增加趋势,微生物硝化作用强烈。底泥中总氮(TN)沿水流方向也呈增加趋势,累计效应比较明显。研究结果为湿地设计的进一步改进提供理论支持。

| Abstract: | The Pingyin constructed wetland of Shandong Province was selected for study of removal efficiency of nitrogen in reclaimed water through analysis of the changes of NH4+-N and NO-3-N contents along the flow direction both in wetland water and sediments.The results showed that the removal of NH4+-N in wetland water was significant;however,as the main existing form of nitrogen in wastewater,NO-3-N increased along the flow direction,and the microbial nitrification was strong.Total nitrogen(TN) in sediments also... |
