| 摘 要： | 在进水不含磷条件下,对膜生物反应器(MBR)系统的运行情况进行了研究。结果表明:微生物充分利用体内储存的聚磷酸盐及死亡细胞和碎片中的磷进行生长,因此混合液悬浮固体(MLSS)仍能增加,最后稳定在8.5 g/L;化学需氧量(COD)处理效果一直较好;氨氮和总氮去除率可达90％及70％;系统经历了丝状菌膨胀和非丝状菌膨胀两个阶段。在缺磷的情况下,MBR系统的处理结果并未受到很大影响。 |

| Abstract: | The running of membrane bioreactor(MBR) without P in the influent was studied.The results show that the microorganisms cought grow up by using polyphosphate in their bodis, or the phosphor released from the dead-bodys; At the initial stage, MISS keeps on increasing, and remains at 8.5 g/L finally; During the experimental period, the chemical oxygen demand (COD) removal efficiency is always stable and excellent.The removals of the NH,+ -N and total nitrogen reach 90% and 70% , respectively after a period of running. Research on the property of MLSS indicates that filamentous bulking and non-filamentous bulking both occur in this system. According to the experimental results, it has no effect on the MBR system when there is no phosphor in the influent. |
