  • 摘要: 针对碳源偏低城市污水，采用厌氧/限氧的序批式活性污泥反应器（A/LOSBR），在连续（CA）和间歇曝气（IA）模式下，研究了亚硝化/反硝化除磷同步发生所需的最适控制策略。实验结果表明，在CA模式下，恒定30 L·h-1的气量，进行同步亚硝化/反硝化除磷的TN和PO43--P去除率分别为88.5%和95.9%；在IA模式下，恒定30 L·h-1的气量，且曝气百分数（AF）和曝气频率（fIA）值为0.5和24时，曝气量比CA模式节省了23%，该工艺的TN和PO43--P去除率分别为91.1%和92.9%。由此可知，同一气量下，IA模式比CA模式的更经济节能，且IA模式在低AF和高fIA工况下进行的同步亚硝化/反硝化除磷过程更稳定持续。
    Abstract: Aiming to treat low-carbon municipal wastewater, we studied the optimal control strategy of nitrosification and denitrifying phosphorus removal under the continuous aeration (CA) and intermittent aeration (IA) modes, using an anaerobic/oxygen limited sequencing batch reactor (A/LOSBR).The results showed that the removal rates of PO43--P and TN were 88.5% and 95.9%, respectively, at 30 L·h-1 in the CA mode.When the aeration fraction (AF) was 0.5 and the aeration frequency (fIA) was 24, 30 L·h-1 of fixed air flux under the IA mode, the aeration savings were 23% more than when the same air flux was used in the CA mode.The removal rate of TN was 91.1% and that of PO43--P was 92.9% under the IA mode.The results showed that the IA mode was more economical and energy saving than the CA mode at the same air flux, low AF, and high fIA.The IA mode was more stable throughout the processes of nitrosification and denitrifying phosphorus removal.
