Abstract

La présente invention concerne un système de traitement des eaux usées et un procédé de traitement des eaux usées. Une cuve de traitement des eaux usées du système de traitement des eaux usés est pourvue d'un cadre de membrane de filtration et d'un dispositif autonettoyant de membrane de filtration dans celui-ci ; le cadre de membrane de filtration soutient une membrane de filtration formée par des contaminants et la membrane de filtration filtre les eaux usées ; le dispositif autonettoyant de membrane de filtration permet à la membrane de filtration de vibrer et de se détacher partiellement pour éviter le durcissement de la membrane de filtration. Le système de traitement des eaux usées de la présente invention permet aux contaminants dans les eaux usées de former la membrane de filtration sous l'effet du cadre de membrane de filtration, sans nécessiter la disposition additionnelle d'une membrane de filtration, de manière à réduire les coûts ; et le dispositif autonettoyant de membrane de filtration permet à la membrane de filtration formée par les contaminants de vibrer et de se détacher partiellement, de manière à prévenir efficacement le durcissement de la membrane filtration, de manière à réduire la fréquence de nettoyage et les coûts de maintenance d'une cuve de traitement des eaux usées, prolonger la durée de vie de la cuve de traitement des eaux usés, et améliorer la capacité de traitement des eaux usées.
