摘要
为在一个生物充气过滤器(BAF ) 的货到付款移动的一个实验模型面对 2,4,6-trinitrophenol (TNP ) 被开发，它沿着床高度联系了自河货到付款到流入的货到付款或水力的装载率。为底层简历降级的全面反应率能首先被描述为假顺序。对反应堆高度的货到付款移动的试验性的数据被用来在实验模型计算参数。在不同反应堆高度的货到付款集中被表示为流入的货到付款集中和水力的装载率的功能， ln (C <sub>0</sub>/C)= 0.124H/Q <sup>0.77</sup><sub>0</sub> 和 ln (C/<sub>0</sub>)=−； 5.63H/L <sup>0.94}</sup>, 分别地，在试验性的条件下面。模型可以被用来为设计以不同的水力的装载率和流入的货到付款集中沿着反应堆高度预言 COD 移动侧面，选择并且 BAF 缩放。
An empirical model for COD removal in a biological aerated filter （BAF） in the presence of 2,4,6-trinitrophenol （TNP） was developed, which related effluent COD to influent COD or hydraulic loading rate along the bed height. The overall reaction rate for substrate biodegradation could be described as pseudo first order. The experimental data of COD removal against reactor height were used to calculate the parameters in the empirical model. The COD concentration at different reactor height was expressed as a function of influent COD concentration and hydraulic loading rate, ln（C0/C）=0.124H/QC0^0.77 and ln（C/C0）=-5.63H/L^0.94, respectively, under the experimental condition. The models may be used to predict the COD removal profiles along the reactor height at different hydraulic loading rates and influent COD concentration for design, selection and sizing of BAF.
