Manejo y tratamiento de lixiviados provenientes de residuos sólidos urbanos

Abstract

The combination of solid waste generates a liquid mixture between organic and inorganic components, which is called leachate, there are several methods for the handling and treatment of them. This literature review paper focuses on the critical description of the different treatment technologies leachates from landfills identifying advantages and limitations. The review begins with topics related to the generation and composition of leachates aimed at identifying the type of treatment available, as well as including a critical description of the different leachate treatment technologies from landfills and the environmental impacts associated with leachates. The literature review allowed identifying that the leachates are characterized by high levels of COD to 60,000 mg / l and that the technology used in Colombia is leachate recirculation, followed by technologies such as evaporation, aerobic lagoons, anaerobic and natural systems, UASB, activated sludge and membrane system lesser percentage
