| 摘 要： | 论文研究了溶解氧(DO)对同步硝化反硝化膜生物反应器(SNdNMBR)处理生活污水过程脱氮除磷的影响.在一定的条件下控制DO浓度于不同的范围,考察MBR内同步硝化反硝化过程及对COD的去除效果.试验结果表明:当水力停留时间(HRT)在6 h左右、C/N(浓度比)约为8和pH在微碱性范围内时,反应器进行低氧曝气且将DO控制在1.0 mg/L左右,系统表现出良好的SNdNMBR过程脱氮除磷效果,膜生物反应器系统对COD、NH3-N、TN和TP的去除率分别达到89.43%、80.5%、75.72%和76.37%.

| Abstract: | The dissolved oxygen（DO） was studied for nitrogen and phosphorus removal of Domestic Sewage by simultaneous nitrification and denitrification membrane bioreactor （ SNdNMBR ） process . Under the certain conditions, the process of SNdN and removal of COD are investigated in MBR with different DO concentration. The results showed that when the operating conditions were the HRT at about 6 h, C/N of about 8, and pH of slightly alkaline , the oxygen concentration in the reactor was low and DO was 1.0 mg/L, the SNdNMBR had a good simultaneous nitrification and denitrification effect on the nitrogen and phosphorus removal, the removal efficiencies of COD,NH3-N,TN and TP are 89.43%,80.5%, 75.72%and 76.37%, respectively. |
