摘　　要：生物流化床技术应用于废水处理领域具有广阔的发展前景。生物流化床反应器对污染物的降解主要依赖于活性生物膜 ,研究生物膜的特性是提高反应器效率的重要手段。本文对描述生物膜特性的主要参数进行了综述 ,其中 ,生物膜种群构成的差异是影响反应器效率的最重要因素 ,本文重点探讨了生物膜中微生物的种群分布特征、种群的生态演替过程与反应器性能的关系。在此基础上 。Biological fluidized bed (BFB) will be greatly developed in wastewater treatment. The biodegradation process depends upon the active biofilm. It is an important approach to study the biofilm characteristics to improve the biodegradable ability of BFB reactor. Several key parameters of the biofilm characteristics are reviewed in this paper. The microbial community structure is the most important factor effecting the efficiency of BFB. Therefore, the relation between the microbial community distribution, ecological succession and the BFB efficiency is specially discussed in this review. Besides, several measures have been put forward to enhance the biofilm characteristics of BFB reactor.
