Diseño del sistema de tratamiento para los residuos recolectados por el hidrosuccionador de la EP- EMAPAG del Cantón Guaranda año 2015.

Abstract

“Design of the treatment system for waste collected by the EP-EMAPAG hydro-suctioner, Guaranda canton”. Technical information or equipment was collected, then 7 samples were taken over a period of six months, considering the points where the hydro-suctioner operated. The last sample was used for specific analysis of flocculation, coagulation and sedimentation, because it showed more alterations in the organoleptic, aesthetic, physical, chemical and microbiological properties. In order to determine the volume of wastewater collected volume values obtained during the gauging period and the historical values between October 2014 and March 2015. Flow measurement of the Technical Management was considered weekly measure the flow. The results of the characterization made to the wastewater had the following concentration outside the permissible limits according to Table 12, Annex 1, Book VI of the TULSMA standard: Color 480NTU, 258 fecal coliforms Nmp/100ml, DOB 11580mg/L, chemical oxygen demand 5089mg/L, total nitrogen 18,54mg/L, suspended solids 228,38mg/L also considering some parameters that are not established in these regulations but are important for aesthetics and indicators in water quality as: 156,43NTU turbidity, total coliforms 760Nmp/100ml, dissolved oxygen 0,84mg/L. From the simulation of treatment processes and primary characterization it was determined to establish the following units: girds, conventional settler, storage and coagulation tank, upflow anaerobic filter, slow filter of sand and activated coal, chlorination tank. The design was performed using the software AutoCAD 2013. It is recommended that the company implement treatment plant to reduce environmental impact and spread of pathogens.
