摘要

摘要: 常温(25±1)℃条件下,研究了不同曝气模式对亚硝化启动和稳定运行的影响。结果表明:长期的连续曝气模式(曝气时间为10 h)无法实现亚硝化的启动,而短期连续曝气模式(曝气时间6 h)和间歇曝气模式(曝气30 min/停曝30 min)皆能够实现亚硝化的启动及稳定运行,NO^-₂-N累积率可分别达到88.81%和64.48%。曝气/停曝模式的切换,能够有效降低亚硝酸氧化菌的活性,同时由于好氧/缺氧环境的切换,也降低了部分氨氧化细菌活性,使得间歇曝气模式的出水NO^-₂-N/NH⁺₄-N能够满足后续厌氧氨氧化工艺的进水需求。连续曝气模式由于较长时间的曝气,可以提供一个稳定的生存环境,虽然有利于氨氧化细菌的生长和代谢,实现较高的亚硝态氮累积率,但无法满足后续的厌氧氨氧化对于NO^-₂-N/NH⁺₄-N的进水要求。

Abstract: The effects of different aeration modes on the start-up and stable operation of nitrification were studied at room temperature (25±1) ℃. The results showed that a long continuous aeration mode (aeration time of 10 h) could not achieve nitrification. However, long continuous aeration mode (aeration time of 6 h) and intermittent aeration mode (aeration time of 30 min/anaerobic of 30 min) could both achieve the start-up and stable operation of nitrification, and the accumulation rate of nitrite nitrogen could reach 88.81% and 64.48%, respectively. The switching mode of aeration/anaerobic could effectively reduce the activity of nitrite-oxidizing bacteria. Meanwhile, the switching of aerobic/anoxic mode could also reduce the activity of some ammonia-oxidizing bacteria, therefore, the effluent NO^-₂-N/NH₄⁺-N of the intermittent aeration mode could meet the influent demand of the subsequent anammox process. Continuous aeration mode could provide a stable living environment due to long-time aeration, which was advantageous to the growth and metabolism of ammonia-oxidizing bacteria and to achieve a higher nitrite accumulation rate, but it cannot meet the subsequent anammox influent’s requirements on ratio of NO^-₂-N to NH₄⁺-N.
