Evaluación de la planta de tratamiento de aguas residuales del sector condesan de la parroquia Quisapincha del cantón Ambato de la provincia de Tungurahua

Abstract

The treatment plant under study is designed for the treatment of domestic wastewater; however, despite the fact that the WWTP is operational, its operation causes inconvenience to the inhabitants of the surrounding areas and those who pass through the sector, since it emits bad odors, causing environmental pollution. This research was carried out in three stages: the first was a topographic survey of the plant area, which is 586.15 square meters, and data was collected on its components and system (distribution tank, valve box, revision boxes, septic tank, upflow anaerobic filter, sludge drying bed, outlet well). In the second, the maximum wastewater flows of the influent and effluent of the treatment plant for 30 days for 8 hours per day were estimated using a quantitative method, as well as the analysis of the composite sample that was tested in the Quality Control Laboratory of the Public Company EP-EMAPA-A, using qualitative methodology, in order to verify whether the pollutant load of the WWTP complies with the parameters of the TULSMA 2015 regulations, Book VI: Table 8. Discharge limits to the public sewage system and Table 9. Discharge limits to a freshwater body. As a result, an operation and maintenance plan was proposed for the WWTP. It is worth mentioning that the efficiency of the treatment plant is favorable, even though there is no adequate maintenance and cleaning of the area in question.
