Abstract:

The quickest way of the starting-up of anaerobic fluidized bed reactor through the biofilm forming process has been studied profoundly. Reactor R1 starts up directly in anaerobic surroundings. While reactor R2 starts up indirectly after forming mold fungi under aerobic condition. The results show mold fungi can increase the rate of biofilm forming, shorten the cycle of starting, and complete in 35 d. In addition, the biofilm forming in such way possesses mechanical property and high-impact strength.

Key words: biofilm, mold fungi, anaerobic fluid bed

摘要：

从生物膜的形成过程,对厌氧流化床反应器的快速启动进行了深入的研究,反应器R1采用在厌氧条件下直接挂膜的方式启动;反应器R2采用先在好氧条件下生成丝状菌,然后在厌氧条件下进行挂膜。结果发现,丝状菌作为生物膜的骨架加速了生物膜的形成,缩短了反应器的启动时间,35d就可以完成启动,而且形成的生物膜具有较好的机械性能和抗冲击负荷能力。
