| 摘 要： | 选用SBR反应器R1和R2接种污水处理厂活性污泥,以生活污水为进水,分别采用一次进水-曝气策略和多次进水-曝气策略运行,对运行过程中粒径变化及处理效果进行研究.实验表明,运行56和39 d后R1和R2成功实现污泥颗粒化;稳定运行后R1和R2中出水COD、 TN和TP浓度(mg·L~(-1))分别为29.7、 13.7、 0.31和19.2、 8.1、 0.37,去除率分别为87.7%、 75.6%、 95.1%和90.1%、 85.6%、 94.2%,其中颗粒平均粒径达到740μm和791μm.结果表明,相同运行时间下,R2中的出水NO~-_3-N浓度和出水TP浓度低于R1.运行后期,R1和R2中DPAO占全部PAOs的比值由最初11.17%分别增至25.47%和34.08%.与一次进水-曝气策略相比,采用多次进水-曝气策略运行在启动初期系统内NO~-_3-N浓度较低,PAOs受到的冲击更小,DPAO富集情况更好,除磷性能更好,利于AGS的形成.
