Stable nitritation is realized because the nitrobacter is sensitive to the changing environment. When the dissolved oxygen and pH values in SBRⅠ and SBRⅡ are 2. 4-3. 0mg/L, 7. 0-8. 5, 1. 5-2. 0mg/L and 7. 0-8. 5 respectively, a lot of nitrate isn't found during operation in two months, and nitrosation rate is over 80% in two aerobic reactors.

将SBRⅠ、SBRⅡ好氧反应器的溶解氧、pH分别控制在7.0-8.5、2.4-3.0mg/L及7.0-8.5、1.5-2.0mg/L时,依赖SBR反应器水质波动大、硝酸菌对环境变化敏感的特点,在较高浓度NH〓-N条件下,实现了稳定的亚硝化反应,系统运行近两个月,没有大量硝酸盐的积累,两个好氧反应器的亚硝化率均在80%以上。
