Diseño de una planta de tratamiento primario de lixiviados para el relleno sanitario Pelileo-Patate, provincia de Tungurahua.

Abstract

The pooling of resources for the treatment of solid waste is a viable alternative that decentralized autonomous governments (GADs) are currently adopting for the adequate management of this waste, as is the case of the Pelileo-Patate solid waste landfill. This landfill, in its quest to comply with the regulations, has the need to design a pretreatment plant for the leachate generated by the degradation of organic and inorganic matter and the infiltration of water from precipitation in the sector. Since Pelileo is a city of high textile production, the waste that arrives at the landfill is dyed fabrics. The dyes used to color the fabrics have elements such as heavy metals, which will give a special characteristic to the leachate produced in the landfill. The design of the pretreatment plant will be focused on the reduction of BOD, TSS and a percentage of heavy metals, so after this physical-chemical pretreatment and with the reduction of the concentration of heavy metals, the leachate can be discharged into the nearby oxidation ponds without increasing the toxicity levels of the wastewater treated in the oxidation pond. Thus, avoiding the inhibition of the microorganisms present in this biological treatment and improving the efficiency of the landfill and the oxidation ponds. This project is expected to remove up to 50% of BOD, 70% of TSS and 90% of heavy metals
