This work proposes a mathematical model as a basis for studying the combined adsorption–ozonation process (Ad/Ox) with the complexity involved in a three-phase system. The description of this operation involves several parameters that describe the system kinetics and adsorption phenomena. This paper analyses the Ad/Ox process compared with simple ozonation, investigating the benefits of activated carbon (AC) in ozonation, primary degradation and mineralization of phenol solutions. This study focuses on Ad/Ox with granular activated carbon (GAC) and analyses how the phenol degradation kinetics depend on the amount of AC. Thus, a priority order of relevance is established for the proposed mathematical model parameters. For example, the adsorption kinetic constant may vary meaningfully within the same process. Finally, this paper studies the GAC behaviour after a given number of cycles, followed by the regeneration process. The calculated kinetic coefficients relating to the liquid and solid media explain the changes in process efficiency.

颗粒活性炭吸附-臭氧混合工艺处理苯酚废水中操作条件的影响分析

这项工作提出了一个数学模型，作为研究吸附-臭氧化过程（Ad / Ox）的基础，该过程复杂且涉及三相系统。此操作的描述涉及描述系统动力学和吸附现象的几个参数。本文分析了与简单臭氧化相比的Ad / Ox工艺，研究了活性炭（AC）在酚溶液的臭氧化，一次降解和矿化中的益处。这项研究的重点是具有颗粒状活性炭（GAC）的Ad / Ox，并分析了苯酚降解动力学如何取决于AC量。因此，为提出的数学模型参数建立了相关的优先顺序。例如，吸附动力学常数在同一过程中可能发生有意义的变化。最后，本文研究了给定数量的循环后的GAC行为，然后进行了再生过程。计算出的与液体和固体介质有关的动力学系数解释了过程效率的变化。
