| 摘 要： | 对厌氧附着膜膨胀床反应器中活性污泥的特性进行了研究。结果表明，载体上生物膜的形成和发展经历吸附、局部挂膜和完全挂膜３个阶段，在此过程中，微生物群演变由以球菌占优势，逐步过渡到丝状菌占优势，厌氧污泥的活性随之提高。酸化状态下的活性污泥表面有许多链球菌和大量的胞外聚物，污泥活性较低。

| Abstract: | The characteristics of activated sludge in the anaerobic attached microbial film expanded bed (AAFEB)reactor were studied. The results showed that there were three consecutive phases in the course of biofilm formation and development,namely,adsorbtion phase, partly coating phase and fully coating phase. ln this process,the predominant microorganisms were changed gradually from coccus to filamentous organisms,which caused anaerobic sludge activity increasing.Under the acidification condition,there were a lot of streptococcus and extracellular polymer on the surface of activated sludge,and the sludge activity was low. |
