| 摘 要： | 对上海梦清园人工芦苇湿地中脱氮生物以及脱氮效果进行1年的动态变化特征分析。结果表明，湿地中氨氮的平均去除率21％，总氮的去除率16％。氮去除效率与水体硝化细菌数和植物量有显著的相关性。作为处理微污染水体用的人工景观湿地．其脱氮效果弱于现有的文献报道，且该湿地反硝化作用不明显，硝酸盐氮在系统中产生累积。图4，表1，参9。

| Abstract: | Efficiency of nitrogen removal and biomass related with nitrogen removal were analyzed in constructed wetland of Meng Qing Garden, The results showed that the wetland could remove NH3 - N by 35% av, TN by 23% av per year. There are significant correlation between nitrogen removal efficiency and the biomass of nitrifying bacteria in water and the Plants. As a landscape wetland for treatment of micro-polluted water, the nitrogen removal efficiency is not as high as previously reported. But the wetland is short of denitrification function and the nitrate cumulates in the wetland. |
