| 摘 要： | 在3个序批式反应器中,利用好氧-缺氧-闲置的运行模式处理实际生活污水,比较了不同曝气时间（2、3和4h）条件下的处理效果,结果表明,在R2（2 h）反应器中成功实现了单级好氧除磷和内聚物驱动的短程硝化反硝化。采用此反应器运行模式,对实际生活污水进行长期处理,反应器的COD、TN和TP的平均去除率分别为85.29%、74.09%和87.97%。本研究表明,在好氧-缺氧-闲置的运行模式下处理生活污水,能成功地实现单级好氧除磷与内聚物驱动的短程硝化反硝化的结合,并且在长期运行的过程中,能稳定地取得较好的脱氮、除磷效率。

| Abstract: | The practical municipal sewage was treated by three sequencing batch reactors applying aerobicanoxic-idle operational method.The results showed that single stage aerobic phosphorous removal and storage compounds driving denitrificaition via nitrite were successfully achieved.The average removal efficiencies of COD,total nitrogen and total phosphorous were 85.29%,74.09% and 87.97%,respectively after long-term treatment.The study demonstrated that aerobic-anoxic-idle operational method could be successfully achieved by the combination of single stage aerobic phosphorous removal and storage compounds driving denitrificaition via nitrite.Additionally,it could achieve a desirable and steady nitrogen and phosphorous removal performance in long-term operation. |
