Diseño de una planta de tratamiento de lixiviados para la Empresa Publica Municipal Mancomunada de Aseo Integral de los cantones Patate y Pelileo EMMAIT-EP en el canton Pelileo, provincia Tungurahua.

Abstract

The objective of this project was to design a leachate treatment plant for the Empresa Pública Municipal Mancomunada de Aseo Integral Patate-Pelileo EMMAIT-EP, in order to reduce the pollutant load and comply with what the Unified Text of Legislation Secondary Environmental stipulates (TULSMA). Book VI, Annex 1, and Table 9. Standard Methods were followed for the examination of water and wastewater and physical, chemical and microbiological characterization was obtained. To determine the data of the flow of the sanitary landfill was used the volumetric method in base to the days that there is greater discharge of residues. It was identified that the parameters outside the permissible maximum limit for discharges to freshwater bodies are: chemical oxygen demand (DQO)3670mg/ l, biological oxygen demand (DBO5) 7060mg/l, total nitrogen 13600 mg / l, total solids 7080mg/1, sulfides 2,60mg / l, surfactants 3,45mg / l. The applied treatment was purely biological with the use of artificial wetlands and a process of evaporation with the use of solar radiation (solar distiller). Efficiency was determined of these treatments in removal the pollutant load, giving the following results in the analysis of the treated water: DQO125 mg / l, DBO5 71 mg / l, total nitrogen 40,2 mg / l, total solids 728 mg / l, sulfides <0,5 mg / l, and surfactants 0,47 mg / l; with a percentage of removal average of 91,4%. The research paper concluded that after the final characterization, the parameters are within the permissible limits and comply with what stipulates the TULSMA. It is recommended to use materials of good quality for the construction of the different equipment to increase the useful life of the equipment and the plant.
