摘　　要：本文主要介绍了厌氧膨胀颗粒污泥床 (EGSB)反应器的特性及研究进展。EGSB反应器是在UASB反应器的基础上发展起来的第三代厌氧生物反应器 ,与UASB反应器相比 ,它增加了出水再循环部分 ,使得反应器内的液体上升流速远远高于UASB反应器 ,污水和微生物之间的接触加强了 ,正是由于这种独特的技术优势 ,使得它可以用于多种有机污水的处理 ,并且获得较高的处理效率。本文还展望了EGSB反应器今后的发展前景。In this paper,the characteristics of Expanded Granular Sludge Bed(EGSB) reactor and its recent research achicvements were reviewed.EGSB reactor is the third generation of anaerobic biological reactor developed on the base of UASB reactor.Compared with UASB reactor,effluent circulation is applied in EGSB reactor,so that the liquid upfolw velocity is much higher,and the contact between wastewater and microorganisms are much more strengthened.Relying on this unique technical advantage,it could be applied to treat many kinds of organic wastewater and high COD removal efficiencies could be obtained.The future development of EGSB reactor was also prospected in this paper.
