Abstract

The paper presented an economic and efficient method of "anaerobic SBR - UASB - SBR " for disposal mature landfill leachate with high COD, ammonia nitrogen concentration but low B/C ratio . Started up the unified process under 500% reflux ratio whose inflow of water maintained 3L/d . Improved the reflux ratio gradually and determined COD NO3-N NO2-N TN NH4-N of the effluent. Under the optimal reflux ratio of 2200%, the removal rates of COD, NH4-N and TN by the system reached 96.30%, 92.12% and 90.57% respectively,the mass concentration of COD,NH4-N and TN in effluent water were 49.52, 2.14, 38.71mg/L respectively. Under the optimal technical parameters,the effluent quality met the specification for emission standard in water quality meets emission standard in Stander for pollution control on the landfill site of municipal solid waste(GB16889-2008).
