%X treating leachate is one of the most important challenges in designing and operating a sanitary landfill. anaerobic treatment u-sing a mixture of leachate and domestic sewage represents a suitable treatment option having good potential applicability in developing countries. the influence of adding leachate from a domestic sanitary landfill on the anaerobic biodegradability of domestic sewage has been evaluated in this paper. five samples were evaluated for the study: 100% domestic sewage (ds), 100% leachate (l) and three leachate mixtures (l) with domestic sewage (ds) as follows: 10%(l):90%(ds), 20%(l):80%(ds) and 30%(l):70%(ds). the samples¡ä anaerobic biodegradability was monitored for 30 days using methane production accumulation and variation in volatile fatty acid (vfa) concentration and composition. a detailed analysis of chemical oxygen demand (cod) composition was performed at the end of the monitoring period. the results of the study showed that a 10%(l):90%(ds) mixture provided the maximum leachate (l) domestic sewage (ds) combination mixture which could be anaerobically biodegradable with no significantly inhibitory effects. mixtures using a higher percentage of leachate showed significantly potential inhibition effects on the anaerobic biodegradation of domestic sewage.
