零价铁（ZVI）越来越多地被添加到厌氧反应器中，以提高各种生物降解性较差的污染物（LBP）的生物转化。本研究旨在建立一个新的结构模型的基础上的厌氧消化模型1（ADM1），以模拟这样的ZVI为基础的厌氧反应器。三种新工艺，即，从ZVI腐蚀的电子释放，从ZVI腐蚀的H2形成，和LBP的转化，被集成到ADM 1。所建立的模型进行了校准和测试使用的实验数据从一个已发表的研究，并验证使用的数据从另一个工作。预测结果与实测结果之间的良好关系表明，所提出的模型是适当的描述ZVI为基础的厌氧系统的性能。我们的模型可以为厌氧系统的设计，开发和应用提供更精确的策略，特别是用于处理各种含LBP的废水。
Zero-valent iron (ZVI) is increasingly being added into anaerobic reactors to enhance the biological conversion of various less biodegradable pollutants (LBPs). Our study aimed to establish a new structure model based on the Anaerobic Digestion Model No. 1 (ADM1) to simulate such a ZVI-based anaerobic reactor. Three new processes, i.e., electron release from ZVI corrosion, H2formation from ZVI corrosion,and transformation of LBPs, were integrated into ADM1. The established model was calibrated and tested using the experimental data from one published study, and validated using the data from another work. A good relationship between the predicted and measured results indicates that the proposed model was appropriate to describe the performance of the ZVI-based anaerobic system. Our model could provide more precise strategies for the design, development, and application of anaerobic systems especially for treating various LBPs-containing wastewaters.
