| 摘 要： | 能耗高和膜污染是限制膜生物反应器(MBR)广泛应用的重要因素.为降低工艺运行能耗和延缓膜污染,以厌氧折流板反应器(ABR)-MBR工艺处理生活污水为例,对工艺结构和脱氮除磷运行条件进行优化.结果表明,通过优化ABR-MBR工艺结构,可降低43%的运行能耗,同时可保持较高的COD、NH+4-N、TN和TP去除效果,平均去除率分别为91%、85%、76%和86%.另外,添加颗粒填料可有效延缓膜污染,不过也改变了膜污染的形成过程,膜内部污染物含量显著增多,碳水化合物含量增加,而蛋白质含量减少,碳水化合物/蛋白质比明显增大.最终,增强了MBR反应器的实际应用性能. |

| Abstract: | High energy consumption and membrane fouling are important factors that limit the wide use of membrane bioreactor (MBR). In order to reduce energy consumption and delay the process of membrane fouling, the process of anaerobic baffled reactor (ABR)-MBR was used to treat domestic sewage. The structure of the process and conditions of nitrogen and phosphorus removal were optimized in this study. The results showed that energy consumption was reduced by 43% through optimizing the structure of ABR-MBR process. Meanwhile, the process achieved a high level of COD, NH4+-N, TN and TP removal, with the average removal efficiencies of 91%, 85%, 76% and 86%, respectively. In addition, the added particulate media could effectively delay membrane fouling, while the formation process of membrane fouling was changed. The extracted amount of carbohydrates increased while the amount of proteins decreased. Finally, the potential was enhanced for the practical application of MBR. |
| Keywords: | anaerobic baffled reactor membrane bioreactor domestic sewage nitrogen and phosphorus removal energy saving and consumption reducing |
