Diseño de un Sistema de Tratamiento de aguas servidas de los pozos de captación en la parroquia rural Matus del cantón Penipe.

Abstract

In this research the design of waste water treatment system of collection wells was carried out in the Rural Parish Matus of canton Penipe comes from sewage system thus minimizing environmental impacts produced to the river Matus. In order to perform this research it was used the experimental method, and water samples were realized for their physical- chemical and microbiological characterization, which were analyzed in the analytical chemical microbiological service laboratory (SAQMIC), Technical Analysis of ESPOCH and Environmental Services of UNACH determining the variables that are outside the permissible limits based on Unified Text of the Secondary Legislation of the Ministry of Environment (TULAS). Standardized Methods APHA, AWWA, WPCF 17-21 ed. and HACH, were employed in studies of characterization of waste water, the same that identify five physical-chemical- microbiological parameters outside the permissible limits, being the following: chemical oxygen demand (COD), biochemical oxygen demand in five days (BOD5), phosphates, settleable solids, fecal coliforms, the research variables for the design of the treatment system. To diminish the variables outside the permissible limit, the sizing was performed by engineering calculation of waste water treatment system, whose design and area constitute: screening (channel with grids) with 0,77 m2, coagulator-flocculator with stirring with 28,33 m2, rectangular sedimentation tank with 31,47 m2, sludge drying bed with 3,33 m2 and disinfection tank with 10,5 m2. The proposed waste water treatment system in Parish Matus will ensure no contamination of the river Matus and comply the rules of the Unified Text of the Secondary Legislation of the Ministry of Environment (TULAS) of Ecuador. It would be important to implement this system of wastewater treatment system with a trained technician to prevent sources of pollution.
