  • 摘要: 基于建立的序批式反应器(SBR),探索实现城市生活污水短程硝化的主要控制因素。研究结果表明,废水温度维持在(30±1)℃、pH值为7.8~8.2的条件下,采用间歇曝气的运行方式,仅驯化培养29 d,成功实现短程硝化,亚硝氮积累率为95%左右。通过对比发现,间歇曝气方式优于连续曝气方式,间歇曝气能有效地将溶解氧(DO)浓度控制在1.0 mg/L以下,从而有利于进行短程硝化反应。此外,温度和pH可以影响亚硝氮的积累效果;当温度在25~35℃、进水pH为7.8~8.2时,亚硝氮的积累情况较好,积累率在91%以上。
    Abstract: Based on the established sequencing batch reactor (SBR), the experiment intended to probe into the main controlling factors to achieve the shortcut nitrification of urban sewage. The results showed that it just took 29 days to successfully achieve shortcut nitrification under the conditions of temperature of (30±1)℃, pH of 7.8~8.2 and intermittent aeration. Besides, the nitrite accumulation rate was around 95%. By comparison, the intermittent aeration is better than the continuous aeration. Intermittent aeration could effectively make dissolved oxygen (DO) concentration under 1.0 mg /L, which was conducive to shortcut nitrification. The accumulation of nitrite had a better effect under the conditions of the temperature of 25~35℃, influent pH of 7.8~8.2, and the accumulation rate was more than 91%.
