  • 摘要: 为了系统研究氮在深型地下土壤渗滤系统中的去除途径,本次实验采用直径30 cm,高200 cm的有机玻璃柱模拟地下土壤渗滤系统;柱内分层装填取自北京顺义的土壤。在水力负荷为8 cm/d的条件下,取得了较好的脱氮效果;氨氮去除率为99.80%;TN去除率为83.68%。通过观察氮沿土柱深度的变化规律发现,在1.30 m以上的区域随着氨氮浓度的降低硝氮浓度逐渐增大,同时总氮浓度也在不断降低,约有30.55%在此区域被去除;通过氮元素质量平衡证明这部分氮是通过厌氧氨氧化反应去除的。在1.30 m以下反硝化反应是脱氮的主要途径,在此过程中难降解有机物被利用。
    Abstract: To research the nitrogen removal way on the process of sewage purification in deep subsurface wastewater infiltration system, the organic glass column with radius of 0.30 m and a height of 2.00 m was used in this experiment; and be layered loading with soil from Shunyi District, Beijing. Under the hydraulic loading of 8 cm/d, high nitrogen removal efficiency on sewage was achieved, the removal efficiency of ammonia nitrogen and TN were 99.80% and 83.68%, respectively. According to the nitrogen change rule along with the soil column height,with the ammonia nitrogen concentration reducing, the nitrate nitrogen concentration increased. At the same time, total nitrogen concentration was also reduced unceasingly, at 1.30 m above 30.55% nitrogen missed. Through mass-balance analysis, it was found that anaerobic ammonium oxidation was responsible for the transformation of nitrogen into gaseous form. At 1.30 m below, nitrogen was removed mainly by denitrification and refractory organics maybe used as carbon source in this process.
