摘　　要：借助于Li^+阶跃示踪实验建立了上流式厌氧污泥床-滤层(UBF)反应器的液体流态多参数模型.该模型将UBF反应器中的污泥床、污泥层、填料层描述为三个含有死区的、通过活塞流、返混流及短路流相连的全混流反应区,进而利用该模型和比基质降解Monod方程建立了UBF反应器基质降解动力学模型,并通过实验取得了精对苯二甲酸废水基质动力学常数.By means of stimulus-response experiments with a Li+ tracer, a multiparametermodel of fluid flow was established for upflow sludge bed-filter (UBF) reactor. It appearedthat the sludge bed, the sludge blanket and the filter can be described as three ideal mixingregions containing dead space, and joined together by plug flow, teturn flow and short circuiting. Furthermore, a model of substrate conversion kinetics for UBF reactors was proposedon the basis of the multiparameter fluid flowing model and the Monod equation of substratebiodegradation. The substrate conversion kinetic constants of pure terephthalic acid wastewa-ter was obtained from the experiments.
