Description
Bu çalışmada, anoksik-aerobik ardışık kesiklireaktörde azot giderme performansına farklı asetik asit/propiyonik asitoranlarının etkisi araştırılmıştır. KOİ ve NH4+-Ngiderimi tüm asetik asit/propiyonik asit oranlarında hemen hemen tamamlanmışolup, asetik asit/propiyonik asit oranından etkilenmemiştir. Ancak, NO3--Ngiderimi asetik asit/propiyonik asit oranı azaldıkça azalmıştır. Buna bağlıolarak; R1, R2, R3, R4 ve R5’de toplam inorganik azot (TIN) giderme verimlerisırasıyla % 55, %52, % 49, % 45 ve % 43 olarak bulunmuştur. Deneysel sonuçlar,asetik asit ile daha yüksek azot giderme verimi elde edildiğini ve karbonkaynağında propiyonik asit oranı arttıkça azot giderme veriminin azaldığınıgöstermiştir.
In this study, the effect of different ratiosacetic acid to propionic acid on nitrogen removal performance in anoxic-aerobicsequencing batch reactor was investigated. COD and NH4+-Nremoval were almost complete at all acetic acid/propionic acid ratios and werenot affected by the acetic acid / propionic acid ratio. However, NO3--Nremoval decreased with decrease in acetic acid/propionic acid ratios. Consequently;the total inorganic nitrogen (TIN) removal efficiencies in R1, R2, R3, R4 andR5 were 55%, 52%, 49%, 45% and 43%, respectively. Experimental results showthat higher nitrogen removal efficiency is obtained with acetic acid and thatthe nitrogen removal efficiency decreases as the propionic acid ratio increasesin the carbon source.
