  • 摘要: 以人工湿地为研究对象,分析了不同C/N下人工湿地的脱氮效果。结果表明,C/N为10时,TN、NO2--N和COD平均去除率分别为(75.36±10.55)%、(86.34±9.23)%和(67.60±4.10)%,都显著高于其他2组系统(p=0.006、0.001、03--N去除率呈现出上升的趋势;NH4+-N刚好相反,C/N为1时,明显要高于其他2种情况(p=02--N和NO3--N去除率均提高了10%以上,且都要明显高于非强化实验条件(p=0.003、0、04+-N和COD去除率没有明显差异,研究结果表明,从微生物角度对系统进水进行前处理有助于提高人工湿地脱氮效率。
    Abstract: The aim of this study was to investigate the removal of nitrogen and the impact of different C/N in constructed wetland. Results indicated that the average removal competence of TN,NO2--N,COD were (75.36±10.55)%, (86.34±9.23)% and (67.60±4.10)%, respectively, which were significantly higher than that of other two systems (p=0.006,0.001,03--N presented a rising trends; while at C/N =1, the average removal amount of NH4+-N was (65.42±14.31)%, showing the largest in those three different C/N (p=02--N,NO3--N increased by more than 10% and considerably higher than non-amplifying test (p=0.003,0,04+-N and COD. From the aspect of microorganisms, the pre-treatment of influent contributed to the improvement of nitrogen removal ability in constructed wetlands.
