Abstract：
In this study, two methods for wastewater treatment plant (WWTP) dimensioning were compared: (1) a traditional guideline-based approach, and (2) a mechanistic model-based approach. The design outputs depended on uncertainties in correlated influent concentrations, which emphasises the importance of uncertainty analysis. The results showed that model-based design could simplify and reduce the time required for uncertainty and sensitivity analysis compared to a conventional design approach, in which the equations are solved manually and iteratively. A benefit of the conventional design approach was the simple interpretation of which factors limited the design capacity. In the end, this study shows the potential, as well as the need for, model-based design of WWTPs.
摘要：
在这项研究中,对污水处理厂(WWTP)尺寸标注的两种方法进行了比较：(1)传统的基于指南的方法，(2)基于机械模型的方法。设计输出取决于相关进水浓度的不确定性，这强调了不确定性分析的重要性。结果表明，与传统的设计方法相比，基于模型的设计可以简化和减少不确定性和灵敏度分析所需的时间。其中方程是手动和迭代求解的。传统设计方法的一个好处是简单地解释了哪些因素限制了设计能力。最后,这项研究显示了潜力，以及需要，基于模型的污水处理厂设计。
