本研究的目的是建立一个数学模型，用于预测臭氧泡扩散器接触器中微小隐孢子虫卵囊的失活。基于半批动力学数据对模型进行了失活率拟合，并用中试失活数据进行了验证。该模型是根据质量平衡原理建立的，结合了从示踪试验、实验测量的病原体灭活、臭氧分解和传质动力学中获得的流体动力学信息。假设ADR反应器内的轴向流体动力学条件接近ADR。ADR模型可用于逆流（水向下流动，气体向上流动），co- 电流（向上流动的水和气体）或反应流室配置。这些选项中的最后一个对应于多室臭氧接触器的一个室部分，该接触器接收存在臭氧残留但未施加臭氧气体的水。

The objective of this study was the development and application of a mathematical model for predicting the inactivation of Cryptosporidium parvum oocysts in ozone bubble-diffuser contactors. The model was fitted with inactivation rate terms based on semi-batch kinetic data, and verified with pilot-scale inactivation data. The model was formulated from mass balance principles incorporating contactor hydrodynamic information obtained from tracer tests, experimentally measured pathogen inactivation, ozone decomposition and mass transfer kinetics. The hydrodynamics inside the contactor chambers were assumed to approach ideal axial dispersion reactor (ADR) conditions. The ADR model could be used for counter-current flow (water flowing downward and gas flowing upward), co-current flow (both water and gas flowing in the upward direction) or reactive flow chamber configurations. The last of these options would correspond to a chamber part of a multi-chamber ozone contactor receiving water with ozone residual present but without ozone gas being applied.
