This paper introduces a new general methodology for incorporating physico-chemical and chemical transformations into multi-phase wastewater treatment process models in a systematic and rigorous way under a Plant-Wide modelling (PWM) framework. The methodology presented in this paper requires the selection of the relevant biochemical, chemical and physico-chemical transformations taking place and the definition of the mass transport for the co-existing phases. As an example a mathematical model has been constructed to describe a system for biological COD, nitrogen and phosphorus removal, liquid-gas transfer, precipitation processes, and chemical reactions. The capability of the model has been tested by comparing simulated and experimental results for a nutrient removal system with sludge digestion. Finally, a scenario analysis has been undertaken to show the potential of the obtained mathematical model to study phosphorus recovery.
本文提出了一种新的通用方法，可在工厂范围建模 (PWM) 框架下系统而严格地将物理化学和化学转化纳入多相废水处理过程模型中。本文提出的方法需要选择发生的相关生化、化学和物理化学转化，并为共存相定义质量传递。作为一个示例，构建了一个数学模型来描述用于生物 COD、氮和磷去除、液-气传递、沉淀过程和化学反应的系统。通过将具有污泥消化的营养物去除系统的模拟和实验结果进行比较，测试了模型的能力。最后，进行了情景分析，以展示所获得的数学模型研究磷回收的潜力。
