摘    要:臭氧化技术可以实现对有机污染物的有效去除,同时兼具绿色环保、工艺流程简单等特点而被广泛应用,而臭氧化模型的构建可以实现对污染物减排的有效预测,对于臭氧化处理污水的工程应用意义重大。本文介绍了臭氧化技术的基本原理,并着重综述了臭氧氧化的动力学模型和反应器建模的研究进展。在臭氧氧化模型的建立中,臭氧的传质和反应是两个最重要的因素。本文首先讨论了臭氧的传质过程,并对其气液两相模型进行了阐述。然后针对忽略臭氧传质的液-液或液-固体系,并根据反应机理,分别总结了常规臭氧氧化、均相催化臭氧氧化和非均相催化臭氧氧化的动力学模型。在充分研究了臭氧氧化的动力学模型后,将其应用到具体反应器的建模中,并总结出模型建立的基本假设。最后指出现有模型存在的一些问题并给出相关的建议,提出臭氧化模型构建的出处是优化工业反应器,实现工程应用。

关 键 词:臭氧  传质过程  动力学  模型预测控制  化学反应器

Abstract:Ozonation can effectively remove organic pollutants, and thus has been widely used because of its environmental protection and simple process. Ozonation model can effectively predict the pollutant emission reduction, which is of great significance to the engineering application of ozonation in wastewater treatment. This article introduced the basic principle of ozonation, and emphatically reviewed the latest research progress of the kinetics model and reactor modeling of ozonation. The mass transfer and reaction of ozone are the two most important factors in the establishment of ozone oxidation model. The article first introduced the mass transfer process of ozone between gas and liquid phase and expounded the associated models. Then, according to the reaction mechanism, the kinetics models of common ozonation, homogeneous catalytic ozonation, and heterogeneous catalytic ozonation were summarized respectively for liquid-liquid or liquid-solid systems without considering ozone mass transfer. Subsequently, the models were applied to model specific reactors, and the basic assumptions of the models were summarized. Finally, the article pointed out some problems in the existing models and gave some relevant suggestions. It is suggested that the construction of ozonation model should always aim at optimizing the industrial reactors and realizing its engineering applications.
Keywords:ozone  mass transfer process  kinetics  model-predictive control  chemical reactors
