  • 摘要: 针对人工湿地中有机碳源不足造成的脱氮效率不高的问题，向人工湿地中投加植物碳源用以改善人工湿地内部碳氮比低的状况。通过比较芦苇秸秆、梧桐树皮、梧桐树叶、玉米芯4种植物碳源分解时有机物、氮元素的释放规律，从而确定玉米芯为最佳植物碳源，并采用水平潜流人工湿地系统模型研究了投加玉米芯对人工湿地系统脱氮效果的影响。试验发现，空白湿地系统COD的平均去除率为38.71%，总氮的平均去除率为34.24%，玉米芯湿地系统则在保证COD平均去除率38.52%的同时，提高总氮平均去除率到70.55%，证明了植物碳源调控提高人工湿地脱氮效果的可行性与高效性。
    Abstract: To solve the problem of low N removal efficiency due to the shortage of organic carbon in wetlands,plant carbon was added to improve the C/N ratio.According to the release characteristics of organic compounds and elemental N,corncobs were chosen as the best plant carbon materials when compared to reed straw,Firmiana bark,and Firmiana leaves.The horizontal undercurrent of the constructed wetland model was used to investigate the effect of corncob addition on N removal efficiency.Compared with the average COD removal rate of 34.24% and average TN removal rate of 34.24% in an untreated wetland,the average removal rates of COD and TN in the plant-supplemented wetland were 38.52% and 70.55% respectively.The experimental results show that plant carbon addition is a viable method to improve N removal efficiency because the materials are readily available and the process is efficient.
