Abstract

This study focuses on the parameter estimation of an industrial activated sludge model using hyperparameter-tuned metaheuristic techniques. The data used in this study were collected on-site from a textile industry wastewater treatment plant. A Modified Activated Sludge Model (M-ASM) was the 'first-principle model’ selected and implemented with suitable assumptions. Advanced metaheuristic techniques, as Adaptive Tunicate Swarm Optimization (ATSO), Whale Optimization Algorithm (WOA), Rao-3 Optimization (Rao-3) and Driving Training Based Optimization (DTBO) were implemented. The hyperparameter tuning was performed with Bayesian Optimization (BO). Optimized metaheuristic algorithms were implemented for model-parameter identification. The Bayesian optimized Rao-3(BO-Rao-3) algorithm provided the best validation results, with a Mean Absolute Percentage Error (MAPE) value of 7.0141 and Normalized Root Mean Square Error (NRMSE) value of 0.2629. It also had the least execution time. BO-Rao-3 is 0.93% to 4.7% better than the other implemented hyperparameter-tuned metaheuristic techniques.

利用超参数调整元搜索法识别工业活性污泥模型

本研究的重点是利用超参数调整元启发式技术对工业活性污泥模型进行参数估计。本研究使用的数据是从一家纺织工业污水处理厂现场收集的。修正的活性污泥模型（M-ASM）是 "第一原理模型"，并在适当的假设条件下实施。采用了先进的元启发式技术，如自适应调谐蜂群优化算法（ATSO）、鲸鱼优化算法（WOA）、Rao-3 优化算法（Rao-3）和基于驾驶训练的优化算法（DTBO）。超参数调整采用贝叶斯优化算法（BO）。优化的元启发式算法用于模型参数识别。贝叶斯优化 Rao-3（BO-Rao-3）算法提供了最佳验证结果，其平均绝对百分比误差（MAPE）值为 7.0141，归一化均方根误差（NRMSE）值为 0.2629。它的执行时间也最短。BO-Rao-3 比其他已实施的超参数调整元启发式技术好 0.93% 到 4.7%。
