Abstract

L'invention concerne un procédé et un dispositif de gestion de la surveillance des eaux usées, le procédé comprenant les étapes consistant : à acquérir, pour chaque point de rejet d'eaux usées, une valeur de paramètre d'eaux usées courante et le degré d'ouverture de vanne courant d'une vanne correspondant à un point de rejet d'eaux usées (110) ; à analyser le niveau de contamination en fonction de la valeur de paramètre d'eaux usées courante de chaque point de rejet d'eaux usées, et à ajuster le degré d'ouverture de vanne des vannes correspondant aux points de rejet d'eaux usées selon ledit niveau de contamination de façon à commander le rejet d'eaux usées par les points de rejet d'eaux usées (120). Au moyen du procédé et du dispositif de gestion de la surveillance des eaux usées ci-décrits, une commande efficace et précise du rejet d'eaux usées par des points de rejet d'eaux usées peut être mise en œuvre afin d'éviter la pollution environnementale et la dégradation de l'alimentation en eau en raison d'un rejet aléatoire, tandis que l'intensité du travail manuel et les coûts de gestion de la surveillance peuvent être réduits au moyen d'une surveillance automatique.
