The COST/IWA Benchmark Simulation Model No 1 (BSM1) has been available for almost a decade. Its primary purpose has been to create a platform for control strategy benchmarking of activated sludge processes. The fact that the research work related to the benchmark simulation models has resulted in more than 300 publications worldwide demonstrates the interest in and need of such tools within the research community. Recent efforts within the IWA Task Group on "Benchmarking of control strategies for WWTPs" have focused on an extension of the benchmark simulation model. This extension aims at facilitating control strategy development and performance evaluation at a plant-wide level and, consequently, includes both pretreatment of wastewater as well as the processes describing sludge treatment. The motivation for the extension is the increasing interest and need to operate and control wastewater treatment systems not only at an individual process level but also on a plant-wide basis. To facilitate the changes, the evaluation period has been extended to one year. A prolonged evaluation period allows for long-term control strategies to be assessed and enables the use of control handles that cannot be evaluated in a realistic fashion in the one week BSM1 evaluation period. In this paper, the finalised plant layout is summarised and, as was done for BSM1, a default control strategy is proposed. A demonstration of how BSM2 can be used to evaluate control strategies is also given.
COST/IWA 基准模拟模型 1（BSM1）已经存在了将近十年。它的主要目的是为活性污泥工艺的控制策略基准测试创建一个平台。事实上，与基准模拟模型相关的研究工作已经在全球范围内产生了 300 多篇出版物，这表明研究界对这类工具的兴趣和需求。最近，IWA 污水处理厂控制策略基准测试工作组的工作重点是扩展基准模拟模型。这种扩展旨在促进在全厂范围内的控制策略开发和性能评估，因此包括废水的预处理以及描述污泥处理的过程。扩展的动机是越来越有兴趣和需要不仅在单个工艺水平上，而且在全厂范围内运行和控制废水处理系统。为了便于进行更改，评估期已延长至一年。延长评估期可以评估长期控制策略，并允许使用在 BSM1 一周评估期内无法以实际方式评估的控制手柄。本文总结了最终确定的工厂布局，并像为 BSM1 所做的那样，提出了默认控制策略。还给出了如何使用 BSM2 来评估控制策略的演示。
