摘要:
采用人工模拟的高氨氮城市污水,对厌氧/好氧/缺氧(A/O/A)序批式活性污泥法反应器内短程同步硝化/反硝化耦合除磷过程的实现及稳定性进行研究.对一个典型周期内水质变化情况进行测定和分析,系统对化学需氧量(COD)、氨氮(NH+4-N)、总氮(TN)、总磷(TP)去除率分别为94.8%,97.6%,89.4%,93.1%.调节曝气量以改变溶解氧质量浓度,结果表明:随着溶解氧质量浓度升高,亚硝化率由97%下降至20%;溶解氧质量浓度过低,会抑制好氧阶段的吸磷过程;溶解氧质量浓度过高,会影响好氧、缺氧阶段磷的有效吸收.
Abstract:
By using synthetic domestic sewage as feed, it was researched that A/O/A sequencing batch reactor activated sludge process was utilized to combine simultaneous shortcut nitrification/denitrification with phosphorus removal. The typical circle was tested and analyzed, and the system removal of chemical oxygen demand(COD), NH+4-N, total nitrogen(TN), total phosphorus(TP)was 94.8%, 97.6%, 89.4%, 93.1% respectively. Dissolved oxygen(DO)concentration was changed by adjusting the aeration,and the result showed: with DO concentration growing up, the shortcut nitrification rate changed from 97% into 20%. Phosphorus absorption process was inhibited at aerobic stage when DO concentration was too low, while the effective absorption of phosphorus was affected during aerobic and anoxic stage when DO concentration was too high.
