摘要：

我国污水处理厂面临着升级改造强化脱氮除磷的需求，A2/O-MBR由于其脱氮除磷效率高和出水水质好的特性在我国得到了广泛的关注和规模化应用。本文介绍了A2/O-MBR工艺研究及应用进展，对我国主要大型A2/O-MBR污水处理厂的运行参数、处理效果、影响因素及MBR单元运行稳定性进行了讨论分析。结果表明A2/O-MBR虽然在我国已得到工程化应用，但仍存在污泥脱水性能恶化、膜污染严重、水处理成本和能耗高等问题；A2/O-MBR适用于用地资源紧张的大城市污水处理厂的改造和建设，但需要十分重视其膜污染控制、降低处理能耗和成本问题的研究。

A2/O-MBRs are received extensive attention and applied commercially for the requirement of enhancing nutrient removal in China. In the current paper, the recent progress in development and application of A2/O-MBRs was reviewed. The operation parameters, treatment results, influencing factors and the operation stability of A2/O-MBRs were presented and discussed. The results showed that there were drawbacks such as deterioration of sludge dewatering, membrane fouling, high costs and energy consumption in A2/O-MBR applications for wastewater treatment. Based on the analysis of the advantages and limitations, it can be found that A2/O-MBRs are suitable to be used to the cities suffer from scarcity of land. However, the problems of membrane fouling, high energy consumption and high cost need to be paid great attention to investigate and to solve in their applications.
