| 摘 要： | 膜生物反应器(membrane bioreactor, MBR)作为一种高效的污水处理及回用工艺,比传统的活性污泥法具有更多优势。然而,膜污染问题是限制其广泛应用的关键性问题。众多研究者已证实Fe3+能有效的改善MBR中混合液的可滤性及减缓膜污染。本文简述了MBR污泥混合液中主要污染物—胞外聚合物(extracellular polymeric substances, EPSs),并总结Fe3 在去除混合液中污染物、减缓膜污染方面的效能及其对污泥混合液的影响。最后,对Fe3 在减缓MBR膜污染的未来研究方向进行展望。

| Abstract: | The membrane bioreactor (MBR) has been considered as one of the most promising processes for wastewater treatment and reclamation with many outstanding advantages over the conventional activated sludge systems. However, membrane fouling is a key problem blocking its wide application. Fe3 has been proved effective for improving membrane filterability and retarding the membrane fouling of the mixed liquor in the membrane bioreactor(MBR) by previous investigations. This review summarizes the extracellular polymeric substances, (EPSs) of mixed liquor in MBR, and Investigate the effect of Fe3 on pollutants removal, membrane fouling and the mixed liquid of MBR. Finally, Prospects for the future trends in mitigating MBR membrane fouling by Fe3 are proposed. |
