Resumen

The wide use of municipal sanitary landfills has drawn attention to the leaching effluent generated, this may be problematic to the site's environment, whether by infiltration or other contaminating modes. Anaerobic digestion has been shown to be one of the most efficient systems with which to treat this type of effluent. This article reviews the techniques used by different authors for leachate characterization, specifically related to refractory and toxic components and their effect on anaerobic treatability. In addition, it covers the treatment of refractory organics, organic and inorganic toxic materials and the nutrient balance for adequate system operation. The main conclusions are that there is ample availability of methods by which to identify the different components present in leachates as well as for their toxicity assessment and that nutrients are in general available in sufficient amounts. Treatability studies are presented which are shown to be of general value and can be used in a straightforward manner.
