常温条件[(22±1)℃]下，采用SBR反应器，探讨延时曝气对常温低氨氮生活污水亚硝化的影响及寻找一种因延时曝气失稳的亚硝化高效恢复策略。结果表明，延时曝气可为NOB创造一个迅速增殖的有利环境，经23d的延时曝气(延迟时间1h)最终使亚硝化系统失稳；且失稳后仅通过限氧无法实现其恢复，而通过增设1h前置厌氧搅拌并缩短曝气时间控制氨氧化率在50%左右，经过60个周期(20d)实现了亚硝化的恢复。

At room temperature conditions [(22±1℃)], by using SBR reactor, it is explored that how delay aeration impact nitrosation stability for low ammonia nitrogen sewage and efficient recovery strategy for nitrosation instability because of delay aeration is looked for. Results show that the delay aeration creates a favorable environment to NOBs so that NOBs can reproduce rapidly, delay aeration of 1h for the 23d eventually makes the nitrosation system instability;nitrosation instability needs to adopt a joint recovery strategy that the additional 1h front stir anaerobic phase and control of ammonia oxidation rate at about 50%by shortening the aeration time is carried out. Then nitrosation can be realized through 60cycle (20d).
