Abstract

The paper focuses on the modelling of bromate formation. An axial dispersion model was proposed to integrate the non-ideal mixing, mass-transfer and a kinetic model that links ozone decomposition reactions from the Tomiyasu, Fukutomi and Gordon (TFG) ozone decay model with direct and indirect bromide oxidation reactions, oxidationofnatural organic matterandits reactions withaqueous bromine. To elucidate the role of ammonia an additional set of reactions leading to bromamine formation, oxidation and disproportionation was incorporated in the kinetic model. Sensitivity analysis was conducted to obtain information on reliability of the reaction rate constants used and to simplify the model.

臭氧化过程中溴酸盐形成的数值模拟。第一部分-模型开发

本文重点研究了溴酸盐地层的建模。提出了一个轴向分散模型，以整合非理想混合、传质和动力学模型，将富康、福米和戈登(TFG)臭氧衰变模型中的臭氧分解反应与直接和间接溴化物氧化反应、天然有机物的氧化及其与溴水溶液的反应联系起来。为了阐明氨的作用，在动力学模型中加入了一系列导致溴生成、氧化和歧化的反应。进行敏感性分析以获得所用反应速率常数的可靠性信息，并简化模型。

期刊介绍： The content, aim and scope of the proposals should comply with the main subject of the journal, i.e. they should deal with mathematical modelling and/or experimental investigations on momentum, heat and mass transfer, unit processes and operations, integrated processes, biochemical engineering, statics and kinetics of chemical reactions. The experiments and modelling may cover different scales and processes ranging from the molecular phenomena up to production systems. The journal language is grammatically correct British English. Chemical and Process Engineering publishes: i) full text research articles, ii) invited reviews, iii) letters to the editor and iv) short communications, aiming at important new results and/or applications. Each of the publication form is peer-reviewed by at least two independent referees.
