Researchers have studied the effects of biofilm accumulation on the terminal settling velocity (Ut) and the expansion coeffi- cient (n) in fluidized bed reactors [15–21].Most of themreported their results from correlations originally derived for rigid par- ticles that were modified for biofilm system applications. In a previous work [22], a sensitivity analysis of correlations pro- posed by these authors for estimation of parameters Ut and n was presented. The aim was to show the dispersion of results using the most quoted correlations. However, they have been mainly applied to aerobic biofilm systems, and seem to be less appropriate for anaerobic systems than the original equation of Richardson and Zaki [23], quite used to calculate n in most works focused on anaerobic fluidized bed reactors (Eq. (4)), and the equation provided by Foscolo et al. [24] to calculate Ut (Eq. (3)). These correlations are valid for the range of Reynolds number (Ret) investigated, and are here used to calculate Ut and n: |

| 研究人员研究了生物膜积累对最终沉降速度（UT）和流化床反应器的膨胀系数（n）的影响。他们大多报道的结果源于最初的生物膜系统应用修改的刚性粒子。在以前的工作[22]，这些作者提出的估计参数UT和N的相关性的灵敏度分析。的目的是为了显示分散使用最引述相关的结果。但是，他们一直主要应用于好氧生物膜系统，似乎要少一些适当的厌氧系统比原来的方程理查森和扎基[23]，相当用来计算在厌氧流化床反应器（式（4）），和Foscolo酒店等提供的公式集中的大部分作品ñ。 [24]来计算UT（式（3））。这些相关的有效期为雷诺数（RET）调查的范围，并在这里用来计算UT和N |
