Biofilters are biological air-phase packed-bed reactors used for the removal of industrial air pollutants such as volatile organic compounds (VOCs) and odors. Because of the economic and environmental benefits, biofilter technology is preferred in applications such as wastewater treatment plants, waste recycling facilities, and several chemical industries over conventional treatment methods such as adsorption, absorption, and thermal oxidation processes. In order to predict the performance of biofilters, mathematical models under steady-state and transient conditions are needed. The transient biofilter models for gas-phase bioreactors are highly complex, as they involve several parameters that are not easily determined for industrial applications. In this work, a practical transient biofilter model is developed and an analytical solution for the transient model is obtained. When this model is compared with the published but more complex model, this new transient model produces almost the same level of prediction with equal comparisons of experimental data for VOCs, benzene, and toluene. This simple model has fewer parameters and will be very useful and practical for industrial applications for the analysis of transient biofilter performance.
生物滤池是用于去除挥发性有机化合物(VOCs)和异味等工业空气污染物的生物气相填充床反应器。由于具有经济和环境效益,与吸附、吸收和热氧化等传统处理方法相比,生物滤池技术在污水处理厂、废物回收设施和一些化学工业等应用中更受青睐。为了预测生物滤池的性能,需要稳态和瞬态条件下的数学模型。气相生物反应器的瞬态生物滤池模型非常复杂,因为它们涉及几个在工业应用中不易确定的参数。在这项工作中,开发了一个实用的瞬态生物滤池模型,并获得了该瞬态模型的解析解。当将该模型与已发表但更复杂的模型进行比较时,这个新的瞬态模型在对VOCs、苯和甲苯的实验数据进行同等比较时,产生了几乎相同水平的预测。这个简单的模型参数较少,对于工业应用中分析瞬态生物滤池性能将非常有用且实用。
