The aim of the present study was to determine the influence of solid filling on the effectiveness of removal of organic substances (as COD) and ammonium from leachate from municipal landfills in SBR and SBBR reactors. The reactors worked on a laboratory scale reactors working under aerobic conditions at constant hydraulic retention time (HRT) of 3 d.COD values in outflow were similar: on average 635 mg O2·dm-3 (SBR) and 646 mg O2·dm-3 (SBBR). Regardless of the presence or absence of filling, nitrate dominated in the effluent. The average concentration was 693 mg NNQ3·dm3·h-1 in SBR and 699 mg NNQ3·dm3 in SBBR. The concentrations of ammonium and nitrite were low, less than 2.9 mg NNH4·dm-3 and 0.5 mg NNO2·dm-3 (SBR), and 3.2 mg NNH4·dm-3 and 0.3 mg NNO2·dm-3 (SBBR). The results indicate that the presence of solid filling did not influence the effectiveness of nitrification in activated sludge.
