Dimensionamiento de una Planta de tratamiento de Aguas Residuales para la Cabecera Parroquial de Juan de Velasco

Abstract

A Sewage Treatment Plant was built in Juan de Velasco Parish, Colta Canton, Chimbor azo determined during seven days by using volumetric methods resulting in a desing flow of 2.98 L/min. go t the physical, chemi ca l and microbiological characterizations some samples were taken during 3 days using a 12 - hour interval full sampling resulting i n the following values: pH(7,40 Und.); temperature (10.1ºC); and nitrates (0,3 mg/L), these are under the permissible limits; while DQO, DBO 5, phosphates, total solids, oil, fat, fecal a nd total coliforms are not under TULSMA permissible limits. The result s of the analysis were used to design the Sewage Treatment Plant with the use of AUTOCAD, which contains input channel, grids, septic tank, fat and oil trap, artificial humidity, disinfection tank and drying beds. The septic tank theoretical removal is: oi l and fat 60 mg/L, DBO 5 14. 035 mg/L, Suspended solids 28 7 mg/L, Artificial Humidity: DBO 5 4.91 mg/L, DQO 23.6 mg/L, Suspended solids 100 mg/L. Artificial Humidity: DBO 5 . For building the plant, it was necessary a relatively flat place which UTM coordinates are: 735705, 9797604, at a height of 3104 meters above sea level in Pangor river bank and 3230 meteres above sea level in the community, its area is 356,51 m 2 , The implementation of the Sewage Treatment Plant in rural areas decontaminate the environment and improve the quality of life of living being, that is why it is recommended to implement the Plant in Juan de Velasco Parish and other rural communities.
