Abstract

Cette invention permet l'asservissement dynamique de l'aération de la station d'épuration dans le but d'optimiser son fonctionnement en termes de qualité des eaux rejetées et de réduction des dépenses énergétiques et économiques, caractérisé en ce qu'il comprend les étapes suivantes : - Une première étape de nitritation commandant l'abaissement de la capacité d'aération de maximale à intermédiaire par un seuil intermédiaire de concentration en dioxygène. - Une deuxième étape de nitratation, aboutissant à l'arrêt de l'aération, asservie à un seuil haut en potentiel redox et ou un seuil bas de concentration en ammoniums. Une temporisation sécuritaire mise en place en cas de réaction trop rapide ou trop lente. - Une troisième étape de dénitrification, à la suite de la nitrification, se déroulant jusqu'à la remise en route du système d'aération commandé par l'intermédiaire d'un seuil haut de concentration en ammoniums ou d'un seuil bas de concentration en nitrates. Une deuxième temporisation sécuritaire mise en place en cas de réaction trop rapide ou trop lente. - La réitération des différentes étapes en continu.This invention allows the dynamic control of the aeration of the treatment plant with the aim of optimizing its operation in terms of the quality of the water discharged and the reduction of energy and economic expenditure, characterized in that it comprises the steps following: - A first stage of nitritation controlling the lowering of the aeration capacity from maximum to intermediate by an intermediate threshold of dioxygen concentration. - A second stage of nitration, resulting in the cessation of aeration, controlled by a high threshold in redox potential and/or a low threshold in ammonium concentration. A safety delay put in place in the event of a reaction that is too fast or too slow. - A third stage of denitrification, following the nitrification, taking place until the restarting of the aeration system controlled via a high threshold of ammonium concentration or a low threshold of concentration in nitrates. A second safety delay put in place in the event of a reaction that is too fast or too slow. - Continuous reiteration of the different steps.
