A hybrid fluidized‐bed bioreactor for water purification was proposed and analyzed. It is a novel type of bioreactor characterized by hitherto unknown stationary and dynamic features. Steady‐state characteristics of this hybrid bioreactor with external liquid circulation are presented. A quantitative analysis of steady‐state properties of the bioreactor was performed with the aid of an original mathematical model developed for a double‐substrate aerobic microbiological process. A steady‐state analysis of aerobic processes characterized by different oxygen demand was performed. The effect of essential parameters was evaluated, including carbonaceous substrate concentration in the feed stream to the apparatus, aeration intensity, total residence time of a liquid in the bioreactor, and height of the bed of fine carrier particles.

混合流化床生物反应器进行生物水处理的理论研究
提出并分析了用于水净化的混合流化床生物反应器。它是一种新型的生物反应器,其特征是迄今为止未知的静止和动态特征。介绍了这种带有外部液体循环的混合生物反应器的稳态特性。借助于为双底物好氧微生物过程开发的原始数学模型,对生物反应器的稳态特性进行了定量分析。对以不同需氧量为特征的好氧过程进行了稳态分析。评估了基本参数的影响,包括设备进料流中的碳质底物浓度,曝气强度,液体在生物反应器中的总停留时间以及细载体颗粒床的高度。
