LANDFILL LEACHATE TREATMEANT USING SEQUENTIAL ANOXIC MOVING BED BIORECTOR/AEROBİC CONTINUOUS STIRRED TANK REACTOR
Abstract
This study was aimed to investigate the performance of sequential anoxic moving bed bioreactor (AnoxMBBR) and aerobic continuous stirred tank reactor (AeCSTR) to remove chemical oxygen demand (COD) and ammonium-nitrogen from landfill leachate. The sequential AnoxMBBR /AeCSTR system was tested at constant hydraulic retention time (HRT) of 48. The performance of this system was evaluated in terms of chemical oxygen demand (COD), ammonium (NH4+), nitrite (NO2-) and nitrate (NO3-) parameters. In AnoxMBBR, nitrate removal (40%) was limited due to low COD removal efficiency. In AeCSTR, COD and ammonium removal efficiencies were obtained as 46% and 71%. Also, partial nitrification in AeCSTR was simultaneously achieved with nitrite accumulation of 1660 mg/L. The results indicated that the AnoxMBBR/AeCSTR system is quite efficient to remove COD and ammonium from landfill leachate, however, the effluent COD and ammonium concentration still did not meet the discharge criteria.
