| 中文摘要: |
| 膜生物反应器(membrane bioreactor, MBR)作为一种新型的污水处理技术,近些年来备受关注。然而,膜污染问题成为了该工艺广泛应用的最大障碍。现已证明,向MBR中投加铁系混凝剂能够减缓膜污染。本文首先综述了不同价态铁离子对MBR污染物去除的影响,进而对铁离子在污泥混合液中分布及迁移转化进行了分析；文中归纳了铁离子不同价态对膜污染的影响,最后对该领域的研究进行了展望。 |
| 英文摘要: |
| Membrane bioreactor (MBR) has received great attention in wastewater treatment for several years. However, the application of MBR is hindered by the membrane fouling which brings the decrease of permeation flux. It has been reported that membrane fouling can be reduced by iron-based coagulant. The article firstly summarized the effects of iron ion with different valence on the quality of MBR effluent. Then, the distribution and transformation of iron in sludge mixed liquor were analyzed. Moreover, the mechanisms of membrane fouling under the presence of iron ion with different valence were clarified. Finally, the future perspectives regarding the influence of iron ion on the performance of MBR were proposed. |
