Diseño de un sistema de tratamiento de aguas residuales domesticas para la ciudad de Quinindé, provincia de Esmeraldas.

Abstract

The objective of this research was to design a wastewater treatment system in Quinindé city, Esmeraldas province. The city currently has a lack of an adequate wastewater treatment system; the design of the system was according to the physicochemical and microbiological parameters required by TULSMA regulation. After the analysis, the without norm parameters were identified: Tensoactives, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Suspended Solids, therefore, the syringe test was treated with the use of the Polychloride Aluminum and using a filter with sand-gravel and zeolite granular media, all this procedure focused to put into operation a domestic wastewater treatment system that consists of: catchment waterway and grid system; followed by a sedimentation process using a conventional sand trap, mixing thank, then a settler and a sand-gravel and zeolite granular media filter and finality a drying bed, this is a suitable and convenient system at economic cost, for wastewater treatment for Quinindé city. The design is a function of the final characterization of the treatment water: BOD 43 mg /l, COD 82 mg/l, Surfactants 0.47 mg/l Suspended Solids 150 mg/l which achieve all the parameters established within the limits of permissible discharges established in TULSMA, for the care of Esmeraldas river and its surroundings, its design reduces considerably the pollution in the water resources and its ecosystem. It is recommended that after the implementation of the system, collect an enough quantity of sludge for its analysis (CREBIT) based on the Standard, Environmentally Sound Management of Sludge from Treatment Plants (RPAMAR).
