  • Description: The present invention relates to a system and equipment for treating sewage comprising the steps of primary, secondary and tertiary treatment. The primary treatment comprises the bar screen (2), grit chamber (3), Parshall flume (4) and grease trap (5) steps. The secondary treatment comprises the biological treatment step, which occurs in part (A) of the reactor (8). The tertiary treatment comprises the steps of hydro cavitation (13), which occurs in the second part (B) of the reactor (8), followed by settling (15), filtration (16), disinfection (17) and hydraulic mixing (17). The biological sewage treatment system in question contemplates an advanced oxidation system with or without media (MBBR) to accomodate various flows, and is capable of treating sewage with industrial and domestic characteristics in an efficient and low-cost manner. La présente invention concerne un système et un équipement de traitement d'eaux usées, comprenant les étapes de traitement primaire, secondaire et tertiaire. Le traitement primaire comprend les étapes de criblage (2), filtre à sable (3), canal Parshall (4) et collecteur de graisse (5). Le traitement secondaire comprend l'étape de traitement biologique, qui se produit dans la partie (A) du réacteur (8). Le traitement teertiaire comprend les étapes d'hydrocavitation (13), qui se produit dans la seconde partie (B) du réacteur, puis la décantation (15), la filtration (16), la désinfection (17) et le mélange hydraulique. Le système biologique de traitement d'eaux usées en question fait intervenir un système du type à oxydation avancée avec ou sans supports (MBBR) pour obtenir des flux variés, et présente la capacité de traiter des eaux usées avec des caractéristiques industrielles et domestiques, de manière efficace et à moindres frais. A presente invenção refere-se a um sistema e equipamento de tratamento de esgoto compreendendo as etapas de tratamento primário, secundário e terciário. O tratamento primário compreende as etapas de gradeamento (2), caixa de areia (3), a calha parshall (4) e caixa de gordura (5). O tratamento secundário compreende a etapa de tratamento biológico, que ocorre na parte (A) do reator (8). O tratamento terciário compreende as etapas de hidrocavitação (13), que ocorre na segunda parte (B) do reator (8), seguido por decantação (15), filtração (16), desinfecção (17) e mistura hidráulica (17). O sistema biológico de tratamento de esgoto em questão contempla um sistema do tipo Oxidação avançada com ou sem mídias (MBBR) para atender a vazões variadas, e com capacidade de tratar esgotos com características industriais e domesticas, de forma eficaz e de baixo custo.
