Diseño y construcción de una micro planta de tratamiento de aguas residuales, con tecnologías de lodos activados en sistema biológico secundario (SBR), en el Centro de Experimentación Ayora, ubicado en el cantón Cayambe

Abstract

The proposed research work has the goal of building and designing a Micro-Wastewater Treatment Plant through an Activated Sludge System in the Secondary Biological System (SBR), these waters come from the Ayora research center, the purpose is that these wastewater is spilled into the sewerage network complying with the maximum permissible limit determined by Ministerial Agreement 097, Book VI. The procedures carried out for the design and construction of the Micro wastewater treatment plant for the Ayora Research Center are presented below. To obtain the results, it was calculated: COD, BOD, pH, sedimentary solids, conductivity, ORP. Next, the micro wastewater treatment plant was built, which has: aeration system, secondary settler. When carrying out the activated sludge treatment test, the sludge rate was known, which was aerated for 5 days 24 hours, obtaining an initial COD parameter of 2360 [mg/L] and final COD of 310 [mg/ L] verifying that it meets the maximum allowable limit to be able to be discharged into the sewage system.
