Azot gideriminde kullanılan biyo reaktörlerde heterotrofik, ototrofik ve miksotrofik proseslerin değerlendirilmesi
Abstract
Bu çalışmada metanol bazlı heterotrofik, tiyosülfat
bazlı ototrofik ve miksotrofik denitrifikasyon proseslerinin nitrat giderme verimleri
karşılaştırılmıştır. Üç biyofilm reaktör kayseri evsel atıksu arıtma tesisinden
alınan aktif çamur ile aşılandı. Başlangıçta, heterotrofik denitrifikasyonun
performansı, artan nitrat konsantrasyonu (50 ila 400mgNO3- / L) altında
değerlendirildi ve reaksiyon süresi sonunda nitrat tamamen tüketildi. Daha
sonra, kükürt/azot (S / N) oranının denitrifikasyon üzerindeki etkilerini
belirlemek için elektron verici olarak tiosülfat kullanılarak ototrofik denitrifikasyon
gerçekleştirilmiştir. Ototrofik koşullar altında maksimum nitrat giderim
verimi, 150mgNO3-/L nitrat konsantrasyonunda S/N oranı
0.63 olduğunda elde edilmiştir. Son olarak, C/N oranlarının (15'ten 3,88'e)
mikstrofik denitrifikasyon performansı üzerindeki etkisi değerlendirildi.
Metanol eklenerek nitrat giderim oranının arttığı ve nitratın tamamen tüketildiği
gözlenmiştir. Optimum C/N oranı % 96 KOİ giderimi ve yaklaşık 3.0 mgNO3-/L.min
nitrat tüketim hızına karşılık gelen 3.88 bulunmuştur. Sonuç olarak heterotrofik
denitrifikasyonun nitrat ve karbon giderim verimleri ototrofik ve mikstrofik
denitrifikasyona göre daha yüksekti.
