A two-stage lab scale anaerobic digester was used for treatment of a high-strength young leachate from shiraz municipal landfill site . Leachate characteristics varied considerably during 8 months of study COD concentration of 48552-62150 mg/l it was found that the system could reduce the COD of the leahate by 92% AT A LOADING RATE OF 2.25Gcod/l/d and 90% at loading rate of 3.37 g COD/L/d . in the next stage a two -stage anaerobic digester was used for treatment of the old leachate from shiraz landfill for comparison . the study was conducted for a period of 7 month as with the case of young leachate characteristics varied considerabley COD concentration of 64350-91308 gCOD/L/d.
