Abstract
The aim of this study was to assess the efficiency of leachate treatment by microbial oxidation in four connected on-site aerated lagoons it a landfill site. The landfill site was found to be in an ageing methanogenic state, producing leachate with relatively low COD (mean value 1740 mg l(-1)) and relatively high ammonium concentrations (mean value 1241 mg l(-1)). Removal of COD averaged 75%, with retention times varying from 11 to 254 days. Overall 80% of the N load was removed within the plant, some by volatilisation of ammonium. Microbial community profiling of the water from each lagoon showed a divergent community profile, presumably a reflection of the nutrient status in each lagoon. In municipal solid waste landfills under similar conditions, leachate treatment through a facultative aerobic system in which sequential aerobic and anaerobic microbial oxidations occurred can readily be achieved using a simple two-lagoon system. suggesting this technology can be economic to install and simple to run.
