摘要: The aim of the study presented was to implement a process model simulate dynamic behaviour pilot-scale for anaerobic two-stage digestion sewage sludge. implemented initiated support experimental investigations process. concept in simulation software package MATLAB(TM)/Simulink(R) is derivative IWA Anaerobic Digestion Model No.1 (ADM1) that has been developed by task group mathematical modelling processes. In present original adapted and applied replicate Testing procedures, including balance checks 'benchmarking' tests were carried out verify accuracy implementation. These combined measures ensured faultless implementation without numerical inconsistencies. Parameters both, thermophilic mesophilic stage, have estimated successfully using data from lab-scale experiments described literature. Due high number parameters structured model, it necessary develop customised procedure limited range be estimated. optimised parameter sets assessed against experiments. Under these conditions, predicted reasonably well pilot scale. (C) 2004 Elsevier Ltd. All rights reserved.
