AB  - This study was aimed to investigate the performance ofsequential anoxic moving bed bioreactor (AnoxMBBR) and aerobic continuous stirredtank reactor (AeCSTR) to remove chemical oxygen demand (COD) andammonium-nitrogen from landfill leachate. The sequential AnoxMBBR /AeCSTRsystem was tested at constant hydraulic retention time (HRT) of 48. Theperformance of this system was evaluated in terms of chemical oxygen demand(COD), ammonium (NH4+), nitrite (NO2-)and nitrate (NO3-) parameters. In AnoxMBBR, nitrateremoval (40%) was limited due to low COD removal efficiency. In AeCSTR, COD andammonium removal efficiencies were obtained as 46% and 71%. Also, partialnitrification in AeCSTR was simultaneously achieved with nitrite accumulationof 1660 mg/L. The results indicated that the AnoxMBBR/AeCSTR system is quiteefficient to remove COD and ammonium from landfill leachate, however, theeffluent COD and ammonium concentration still did not meet the dischargecriteria.

N2  - Bu çalışmada, çöpsızıntı sularından kimyasal oksijen ihtiyacını(KOİ) ve amonyum-azotu gidermekiçin ardışık anoksik hareketli yatak biyoreaktörün (AnoxHYBR) ve aerobiksürekli karışımlı tank reaktörün (AeSKTR) performansını araştırmak amaçlandı.Ardışık AnoxMBBR/AeCSTR sistemi, 48'lik sabit hidrolik bekletme süresinde (HRT)test edildi. Bu sistemin performansı, kimyasal oksijen ihtiyacı (KOİ), amonyum(NH4+), nitrit (NO2-) ve nitrat (NO3-)parametreleriaçısından değerlendirildi. AnoxHYBR’de, düşük KOİ giderim verimi nedeniylenitrat giderimi (% 40) sınırlıydı. AeSKTR’de KOİ ve amonyum giderim verimlerisırasıyla % 46 ve% 71 olarak elde edildi. Ayrıca, AeSKTR’de 1660 mg / L nitritbirikimi ile kısmi nitrifikasyon sağlandı. Sonuçlar, AnoxHYBR / AeSKTR sistemininçöp sızıntı sularından KOİ ve amonyum giderimi için oldukça verimli olduğunu,ancak çıkış KOİ ve amonyum konsantrasyonunun hala deşarj kriterlerinikarşılamadığını göstermiştir..
