Abstract
In this study, the treatment of landfill leachate (LFL) and domestic wastewater using an aerobic moving bed biofilm reactor (AeMBBR) was investigated. AeMBBR was filled with 30 % (v:v) biocarrier material (Kaldnes K1). The tested volumetric ratio of landfill leachate was 10%. The impact of varying hydraulic retention times (HRTs) (24-12-6 h) at a constant dissolved oxygen (DO) of 3.2 mg/L was investigated for system optimization. AeMBBR was successfully operated (HRT: 6h) for LFL and domestic wastewater treatment corresponding to 94 %, and 78 % ammonium nitrogen (NH4-N) and total organic carbon (TOC) removals, respectively. Additionally, Proteobacteria (66%) have been identified as the predominant culture in the biofilm layer, which plays a significant role in the co-treatment of domestic wastewater and LFL. Considering the results obtained; it was found that a significant amount of ammonium nitrogen was successfully removed.
