Abstract

The activated sludge models (ASMs) commonly used by the International Water Association (IWA) task group are based on chemical oxygen demand (COD) fractionations. However, the proper evaluation of COD fractions, which is crucial for modelling and especially oxygen uptake rate (OUR) predictions, is still under debate. The biodegradation of particulate COD is initiated by the hydrolysis process, which is an integral part of an ASM. This concept has remained in use for over 30 years. The aim of this study was to verify an alternative, more complex, modified (Activated Sludge Model No 2d) ASM2d for modelling the OUR variations and novel procedure for the estimation of a particulate COD fraction through the implementation of the GPS-X software (Hydromantis Environmental Software Solutions, Inc., Hamilton, ON, Canada) in advanced computer simulations. In comparison to the original ASM2d, the modified model more accurately predicted the OUR behavior of real settled wastewater (SWW) samples and SWW after coagulation-flocculation (C-F). The mean absolute relative deviations (MARDs) in OUR were 11.3-29.5% and 18.9-45.8% (original ASM2d) vs. 9.7-15.8% and 11.8-30.3% (modified ASM2d) for the SWW and the C-F samples, respectively. Moreover, the impact of the COD fraction forms and molecules size on the hydrolysis process rate was developed by integrated OUR batch tests in activated sludge modelling.

摘要

国际水协（IWA）任务组常用的活性污泥模型（ASMs）基于化学需氧量（COD）分数。然而，COD 分数的正确评估对于建模，尤其是耗氧速率（OUR）预测至关重要，目前仍存在争议。颗粒态 COD 的生物降解是由水解过程引发的，水解过程是 ASM 的一个组成部分。这一概念已经使用了 30 多年。本研究旨在验证一个替代的、更复杂的、改良的（活性污泥模型 2d 号）ASM2d 模型，用于 OUR 变化的建模，并通过实施 GPS-X 软件（Hydromantis Environmental Software Solutions，Inc.，安大略省汉密尔顿）开发一种新的颗粒态 COD 分数估算方法，在高级计算机模拟中。与原始 ASM2d 相比，改良模型更准确地预测了实际沉淀废水（SWW）样本和混凝-絮凝（C-F）后的 OUR 行为。OUR 的平均绝对相对偏差（MARD）分别为 11.3-29.5%和 18.9-45.8%（原始 ASM2d）与 9.7-15.8%和 11.8-30.3%（改良 ASM2d），用于 SWW 和 C-F 样本。此外，通过在活性污泥建模中进行 OUR 批量测试，开发了 COD 分数形式和分子大小对水解过程速率的影响。
