Abstract

In this study, the effect of dissolved oxygen control at the aerobic phase on nitrogen removal performance in anoxic-aerobic sequencing batch reactor was investigated. The study was completed in two sequencing batch reactor, without dissolved oxygen control at the aerobic phase (R1) and with dissolved oxygen control at 2 mg/L at the aerobic phase (R2). TIN removal efficiencies in R1 and R2 were % 46 and % 53, respectively. The results demonstrated that the higher nitrogen removal efficiency was achieved with dissolved oxygen control at 2 mg/L at the aerobic phase. Moreover, lower electricity consumption and saving in operation costs will be achieved by means of aeration control.

Özet

Bu çalışmada, anoksik-aerobik ardışık kesikli reaktörde azot giderme performansına aerobik fazdaki çözünmüş oksijen kontrolünün etkisi araştırılmıştır. Aerobik fazda çözünmüş oksijen kontrolünün yapılmadığı ardışık kesikli reaktör (R1) ve aerobik fazda çözünmüş oksijen konsantrasyonunun 2 mg/L’de kontrol edildiği ardışık kesikli reaktör (R2) olmak üzere iki ardışık kesikli reaktörde çalışma tamamlanmıştır. TIN (Toplam inorganik azot) giderme verimi R1’de % 46, R2’de % 53’dür. Sonuçlar; aerobik fazda çözünmüş oksijen konsantrasyonunun 2 mg/L’de kontrol edilmesiyle daha yüksek azot giderimi elde edildiğini göstermiştir. Ayrıca, havalandırma kontrolü ile daha az elektrik tüketimi ve işletme maliyetinde tasarruf elde edilecektir.
