Programa de manejo integral para la disposición final de lodos generados en la Planta de Tratamiento de aguas residuales domésticas del sector Miriumi, Cantón Sucúa.

Abstract

The objective of this technical focus work was to carry out a comprehensive management program for the final disposal of sludge generated in the domestic wastewater plant (PTARD) of the Miriumi Sector, Sucúa Canton. The initial environmental review was prepared where the processes and activities of the PTARD were characterized, to quantitatively and qualitatively determine the sludge generated, with this information an environmental impact assessment was carried out, applying the Leopold Matrix, finding 8 positive impacts and 16 negative impacts on the generation and management of the PTARD - Miriumi Sector and at the same time the importance and magnitude to the relationship between the components and environmental categories was valued. This mud was then subjected to physical-chemical and microbiological analyzes (Arsenic, Chromium, Cadmium, Copper, Nickel, Lead, Zinc, Mercury, Fecal Coliforms, Salmonella SP, Helminth Eggs, Oils and fats, Organic Matter, Nitrogen, Phosphorus , Potassium) necessary for the classification, treatment, and final disposal of waste sludge established in NOM-004-SEMANART-2002. The results obtained showed that the sludge generated in the PTARD did not contain heavy metals of importance, so according to the methodology of ISO 14001, proposals were established focused on the objectives, goals and activities for the final disposal of sludge in management in conjunction with the landfill processes summarized in waste management and occupational safety programs.
