摘要
研究了DO、C/N、pH等生态因子对膜生物反应器同步硝化反硝化的影响 .结果表明 ,只有在各生态因子保持得当的条件下 ,同步硝化反硝化才能顺利地进行 .DO为 1mg/L左右、C/N比为 3 0左右、进水 pH值约 7 2左右时COD、NH+4、TN的去除率分别为 96%、95%和 92 %
The influence of dissolved oxygen(DO), C/N and pH on simultaneous nitrification and denitrification in the membrane bioreactor was studied. The experimental results showed that only under condition that each ecological factor was maintained relative steady, simultaneous nitrification and denitrification might proceed smoothly. When DO, C/N and pH of feed water was 1mg/L, 30 and 7.2, the removal rate of COD, NH + 4, and TN were 96%, 95% and 92% respectively.
