| 中文摘要 |
| 将微孔炭管曝气膜置于厌氧折流板反应器（ABR）隔室内，构建一种新型复合式生物反应器（HMABR），通过MABR与ABR的耦合作用强化ABR处理污水的功能，降解其中COD、NH+4-N和TN.结果表明，将驯化好生物膜的炭管曝气膜加入反应器第3隔室后，在膜内腔气压0.025 MPa，HRT=24 h，进水COD为2?000 mg/L，NH+4-N为50 mg/L的条件下，系统发生同时硝化反硝化，出水COD、 NH+4-N分别从加膜前的156 mg/L、 36 mg/L左右下降到45 mg/L、 6 mg/L左右，TN去除率达到87.66%，第3隔室挥发性脂肪酸（VFA）减少77.12%，总产气量减少30%. |
| 英文摘要 |
| New type hybrid biological reactor was developed by initiating the carbon membrane aeration in ABR which was augmented with carbon aerated membranes to improve wastewater treatment by removing COD, NH+4-N and TN.The results showed that on the conditions of intra-membrane pressure of 0.025 MPa, HRT 24 h, influent COD 2 000 mg/L, NH+4-N 50 mg/L, simultaneous nitrification and denitrification was happened, and COD and NH+4-N decreased from 156 mg/L，36 mg/L to 45 mg/L，6 mg/L respectively after the membrane aeration with biofilm was initiated in the third compartment of ABR.TN removal reached 87.66%, and VFA and biogas was decreased by 77.12% and 30%, respectively. |
