| 摘 要： | 通过连续运行MBR研究了DO、HRT、C／N对膜生物反应器处理效果的影响。试验结果表明：当CODMn在2．1—12．8mg／L范围内，C／N为10：1，HRT为5h时，当DO为1mg／L时，TN的去除率达到最大值56．43％，而DO过高或过低都会影响同步硝化反硝化的进行；控制DO为1mg／L，其余操作条件不变，当HRT为4h，TN的去除率达到最大值57．29％；C／N为20：1时，MBR对水中的CODMn、NH3-N和TN等的去除率均达到较好的处理效果；因此，膜生物反应器的最佳操作条件是DO为1mg／L，HRT为4h,C／N为20：1。

| Abstract: | Through eontinons rurming of MBR, irdlunenees of DO, HRT and C/N on treatment efficiency of membrane bioreactor were studied. The results showed： CODMn is 2.1 - 12.8 mg/L, C/N is 10： 1, HRT is 5 h, when DO is 1 mg/L, the removing rate of TN is the highest and reaches 56.43%, but higher DO or lower DO is able to affeet simultaneous nitrifieation and denitrification process; DO is 1 mg,/L, other operation conditions are invariable, when HRT is 4 h, removing rate of TN is the highest and reaches 57.29% ; when C/N is 20：1 ,treatment efficiency of MBR for CODMn, NH3 - N and TN is well. The best operation conditions of MBR is as follows： DO is 1 mg/L HRT is 4 h. C/N is 20： 1. |
