| 摘 要： | 采用单级A/O程序复合膜生物反应器(HSMBR)处理高氨氮废水,研究在低DO浓度下系统对有机物、氨氮和总氮的去除效率。研究结果表明:在低DO浓度下,CODCr、氨氮的平均去除率分别为94.4%和92.8%。由于进水CODCr/TN值仅为2.01,则使得总氮平均去除率仅为69.4%,但是当系统亚硝化累积率从60.5%～67.1%提高到83.5%～86.4%时,系统总氮去除率提高了17.7%。另外,维持低DO浓度可以实现亚硝酸型同时硝化反硝化反应。

| Abstract: | The removal rates of COD_ Cr ,ammonia and total nitrogen(TN) were studied at low DO concentration in single-stage anoxic/aerobic hybrid submerged membrane bioreactor treating wastewater with high ammonia concentration.The experimental results showed that the COD_ Cr and ammonia average removal rate reach 94.4% and 92.8%,respectively.Because of the low influent COD_ Cr /TN ratio(=2.01),the TN average removal rate was only 69.4%,while TN removal rate could be increased by 17.7% with the nitrite accumulation ratio increasing from 60.5%～67.1% to 83.5%～86.4%.Moreover,simultaneous nitrification and denitrification (SND) via nitrite at low DO level could be realized. |
