Conceptual approach for ADM1 application

摘要

This paper introduces a conceptual approach to apply the IWA Anaerobic Digestion Model no. 1 to simulate digester dynamics. The illustrated modelling approach avoids laborious measurements to characterise the influent according the extensive list of components defined in the model. It rather uses the model to make a better characterisation of the inflow. An update to the model is introduced to describe the effect of hydrodynamics on solids retention. The update is useful for the simulation of high rate reactors. The application of the approach to real wastewater treatment with high dynamics shows excellent simulation results.
