| 中文摘要 |
| 利用膜曝气生物膜外层的厌氧状态与厌氧折流板反应器内部环境相融合的特性，分别启动驯化厌氧折流板反应器和膜曝气生物膜反应器，将驯化好的膜组件置入运行稳定的厌氧隔室内构成耦合反应器.当进水COD和NH+4-N浓度分别为1 600 mg/L和80 mg/L时，膜组件置入后反应器出水中的COD和VFA含量分别降低了59.5%和68.1%，对含氮污染物的去除率达到83.5%.当进水有机负荷提高50%时，耦合反应器出水COD浓度仍处于60 mg/L以下，具有良好的抗有机负荷冲击能力.因为流入液体中有机底物的减少和硝态氮的增加，使得3号隔室的沼气产量和甲烷含量均明显减少，但是取而代之的是更为稳定和优良的出水水质.此工艺实现了单一反应器处理中高浓度有机含氮废水的同时去碳脱氮功效. |
| 英文摘要 |
| Based on the consistent anaerobic status of outer layer of membrane-aerated biofilm reactor (MABR) and internal anaerobic baffled reactor (ABR),MABR and ABR were started up separately. The aerating membrane module was installed into a compartment of anaerobic baffled bioreactor to form the Hybrid MAB-ABR (HMABR). After the installation of membrane module,total COD and VFA concentrations in the HMABR effluent were deceased by 59.5% and 68.1% respectively,with increased nitrogenous pollutant remove efficiency by 83.5%,at influent COD concentration of 1 600 mg/L and NH+4-N concentration of 80 mg/L. When organic loading rate was increased by 50%,the effluent COD concentration was still below the level of 60 mg/L,indicating its good capability of counteracting influent organic loading fluctuation. Due to the decreased COD concentration and increased nitrate concentration in the third compartment after installing the membrane module,the biogas volume and methane contents in the third compartment were decreased,resulting in the steady and excellent effluent quality. In this hybrid process,the improved simultaneous removal of carbon and nitrogen for high-strength nitrogenous organic pollutants was realized in a single reactor. |
