摘　　要：膜生物反应器(MBR)曾被认为是一项成熟并代表未来的污水处理技术,在21世纪初的十年中获得空前应用,并一度有取代传统活性污泥工艺(CAS)之趋势。然而,MBR工程应用数量近年在全球市场骤降,与其在中国市场不断升温的"热像"形成鲜明对比。究其原因,高能耗和膜污染等诟病使其在技术、经济与管理等方面综合比较远不如CAS,有悖可持续发展的全球理念。基于MBR发展历程,分析衰落原因,展望未来应用。MBR工程应用在全球范围内已理性回归,对过热的中国市场应是一种启示,特别是对中国目前兴起的地下式MBR。Membrane bioreactors （MBR） were once recognized a mature and future wastewater treatment technology, which were extensively applied in the first decade of the century, and had a tend- ency to replace the conventional activated sludge process （CAS）. However, MBR did not become the hot favorite technology as expected ten years ago; their engineering applications were in sharp contrast to the rising ＂overheated＂ phenomena in China. The reason for the decline is attributed to the drawbacks on en- ergy consumption and membrane fouling, which makes MBR inferior to CAS in sustainability evaluated comprehensively by technology, economy and management. Based on the developed process of MBR, the reason of the decline is analyzed, and the further application of MBR is prospected. The rational return of MBR applications should be an inspiration to the MBR market in China, especially to underground MBR that are emerging at present in China.
