Abstract

Generation of solid waste is directly allied with the population growth, for this reason it will require proper management [1]. A sanitary landfill is a form of final disposal of municipal solid waste that must be designed and managed to reduce possible impacts on the environment. One of the problems associated with the use of this technique is the generation of leached from the decomposition of organic matter, since it is a polluting liquid, its handling and adequate treatment is essential. In this work the operation of the Romerillos Sanitary Landfill in Mejía was evaluated from its infrastructure to the generation and management of leachate prior to entering the primary treatment plant and its recirculation to the closed stages. To do this, a study of the site and an investigation of the component selected for analysis were carried out: topography, effluents, pumping system and leachate recirculation. The results obtained include maps of the landfill and its analyzed components, database of leachate flows and behavior over time; an estimated of the amount of leachate generated of approximately 73 m3/day was obtained. It was also found that the current pumping system can be improved by modifying the diameter of pipes or changing the pump potency and that the recirculation that is currently taking place in the landfill can be used as a pretreatment.
