Abstract

Bu çalışmada, ardışık
kesikli bir reaktör ile sentetik atıksudan nutrient giderimi farklı çamur
yaşlarında çalışılmıştır.  Ardışık
kesikli reaktör anaerobik (130 dakika), aerobik (330 dakika) ve anoksik (210
dakika) fazlar şeklinde işletilmiştir. Anoksik fazdan sonra 45 dakika çökelme
ve 5 dakika boşaltma fazı uygulanmıştır. Reaktör 6 gün çamur yaşında
işletildiğinde, ortalama olarak %92 KOİ, %81 NH₄-N ve %26 PO₄-P
giderimi gözlenmiştir. Çamur yaşı 10 günde sabit tutulduğunda ortalama olarak
%93 KOİ, %90 NH₄-N ve %13 PO₄-P giderimi sağlanmıştır. 15
günlük çamur yaşında ise ortalama olarak %92 KOİ, %79 NH₄-N ve %17
PO₄-P giderimi elde edilmiştir. En yüksek KOİ (%93) ve NH₄-N
(%90) giderimi 10 günlük çamur yaşında belirlenirken en iyi PO₄-P
giderimi 6 günlük çamur yaşında sağlanmıştır. KOİ ve NH₄-N giderim
verimi ile karşılaştırıldığında PO₄-P için oldukça düşük giderim
verimi gözlenmiştir.

Nutrient Removal in Anaerobic/Aerobic/Anoxic Sequencing Batch Reactor at Different Sludge Ages

Abstract

In this study,
nutrient removal from synthetic wastewater by a sequencing batch reactor was
studied at different sludge ages. The sequencing batch reactor was operated in
anaerobic (130 minutes), aerobic (330 minutes) and anoxic (210 minutes) phases.
After the anoxic phase, settling phase of 45 minutes and discharge phase of 5
minutes were applied. When the reactor was operated at sludge age of 6 days,
average 92% COD, 81% NH₄-N and 26% PO₄-P removal were
observed. When the sludge age was kept constant at 10 days, COD, NH₄-N
and PO₄-P removal were achieved to be average 93%, 90% and 13%,
respectively. At sludge age of 15 days, average 92% COD, 79% NH₄-N
and 17% PO₄-P removal were obtained. The highest COD (93%) and NH₄-N
(90%) removal was determined at the sludge age of 10 days, while the best PO₄-P
removal was achieved at the sludge age of 6 days. Compared with COD and NH₄-N
removal efficiency, PO₄-P removal efficiency was appeared very low.
