| 摘 要： | 研究了生物过滤法处理含氨废气的技术，实验中考察了气体的停留时间、进气方式、进气中氨浓度等因素对氨法除率的影响，当进气中氨的浓度分别为１５．２、７５．９和１５．２０ｍｇ（ＮＨ３）／ｍ＾３时，生物过滤反应器对氨的去除均在９５％以上，反应时间是３２ｓ，处理后的气体中氨的浓度可以达到国家一级排放标准，对填料中各形态氮浓度的分析证明氨在反应器中的转化以硝化反应为主。

| Abstract: | Biofiltration technique for disposing ammonia-contaminated gas streams was investigated.The effects of retention time, gas introducing ways and initial concentration of ammonia on the ammonia removal efficiency were studied.The ammonia removal efficiency was higher than 95% when the inlet ammonia concentration was 15.2, 75.9 or 152.0mg(NH3)/m3, and the ammonia elimination rate was 0.020, 0.078 or 0.156 g/(kg·d).The experimental results indicated that the optimum gas introducing way is counter flow and the preferable retention time was 32s.It is found that ammonia is nitrified to nitrate in the reactor. |
