Abstract

Bu çalışmada, ardışık kesikli reaktör (AKR) ve ardışık kesikli biyofilm reaktörün (AKBR) birlikte nitrifikasyon denitrifikasyon (BND) performansına farklı C/N oranlarının (5, 10 ve 15) etkisi karşılaştırılmıştır. Her iki reaktörde % 90’nın üzerinde KOİ giderme verimleri elde edilmiş olup, KOİ giderimi farklı C/N oranlarından etkilenmemiştir. Farklı C/N oranlarının reaktörlerin NH4+-N giderme verimine etkisi az olmasına karşın TN giderme verimine etkisinin daha büyük olduğu belirlenmiştir. Her iki reaktörde C/N oranı arttıkça TN giderme verimi ve birlikte nitrifikasyon denitrifikasyon verimi artmıştır. AKBR’de birlikte nitrifikasyon denitrifikasyon verimi AKR’den daha yüksek bulunmuştur. Sonuçlar, her iki reaktörde farklı C/N oranlarının etkisinin aynı olduğunu ve AKBR’de daha yüksek azot giderimi ile daha etkili birlikte nitrifikasyon denitrifikasyonun elde edildiğini göstermiştir.
