Procédé à boues activées pour le traitement d'effluents papetiers : de la conception d'un pilote à la validation de modèles

Abstract : Activated sludge processes monitoring is difficult to manage altogether because of their slow dynamics, their complex behavior but especially because of the lack of available information regarding the process state. This assessment is even more real for papermill effluents, because of the few means available for instrumentation. Human operators need efficient tools to assist them for taking decisions to enhance treatment quality. A four steps approach is therefore proposed to develop a relevant tool for decision aid: modelling, estimation, behavior prediction, and action proposal. Bases of this tool have been developed in this work: a paper mill model has been validated on experimental data obtained with industrial papermill effluent. In order to avoid specificities and constraints linked to industrial processes, a modular, semi-industrial scale and supervised pilot plant has been carried out in order to perform a large range of experimental studies. Model design has been realised by reduction of the ASM1 biological model, thanks to the choice of the reaction scheme. The need of disposing of a specific papermill model has been pointed out. Validation of the papermill model has been carried out on data collected from the pilot plant, fed with a real papermill wastewater. As the results are really satisfying, the model can be now included in the other steps of the decision aid tool, leading to an actual control of the quality of the treated water issued from the activated sludge biological treatment process with papermill effluent.
