LANDFILL LEACHATE TREATMEANT USING SEQUENTIAL ANOXIC MOVING BED BIORECTOR/AEROBİC CONTINUOUS STIRRED TANK REACTOR
Öz
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.

ARDIŞIK ANOKSİK HAREKETLİ YATAK BİYOREAKTÖR / AEROBİK SÜREKLİ KARIŞIMLI TANK REAKTÖR KULLANILARAK ÇÖP SIZINTI SULARININ ARTITIMI
Öz
Bu çalışmada, çöp
sızıntı sularından kimyasal oksijen ihtiyacını(KOİ) ve amonyum-azotu gidermek
için ardışık anoksik hareketli yatak biyoreaktörün (AnoxHYBR) ve aerobik
sürekli 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-)parametreleri
açısından değerlendirildi. AnoxHYBR’de, düşük KOİ giderim verimi nedeniyle
nitrat giderimi (% 40) sınırlıydı. AeSKTR’de KOİ ve amonyum giderim verimleri
sırasıyla % 46 ve% 71 olarak elde edildi. Ayrıca, AeSKTR’de 1660 mg / L nitrit
birikimi ile kısmi nitrifikasyon sağlandı. Sonuçlar, AnoxHYBR / AeSKTR sisteminin
çöp sızıntı sularından KOİ ve amonyum giderimi için oldukça verimli olduğunu,
ancak çıkış KOİ ve amonyum konsantrasyonunun hala deşarj kriterlerini
karşılamadığını göstermiştir..
