Avaliação de desempenho da estação de tratamento de lixiviado da Central de Tratamento de Resíduos da Zona da Mata – Juiz de Fora/MG

Abstract

In Brazil, the generation of municipal solid waste has been increasing significantly, driven by strong population growth. Consequently, finding suitable areas for proper disposal of municipal solid waste has become an increasingly challenging task. Sanitary landfills are considered an environmentally correct solution for waste disposal. However, they generate biogas and leachate as by-products. Leachate is a liquid effluent characterized by high recalcitrance, low biodegradability, a dark color, and a strong odor. If discharged into the environment without prior treatment, it can cause severe damage to the environment and public health. Selecting the most technically and economically viable technology for its treatment is crucial, as the treated effluent must comply with the discharge parameters established by relevant legislation. This study evaluates the performance of the system used by the Zona da Mata Waste Treatment Center, located in Juiz de Fora/MG, in treating leachate. The results indicate that the leachate treatment plant at CTR Zona da Mata complies with the DN COPAM/CERH 01/2008 standards. Additionally, the study determined the leachate generation rate per inhabitant, which was 0.21 L/inhabitant/day.
