Özet
Ardışık kesikli işletme ile sentetik atıksudan nutrient giderimi farklı hidrolik alıkonma sürelerinde çalışıldı. Nutrient giderme prosesi anaerobik (An), anoksik (Anok), oksik (Ok), anoksik (Anok), oksik (Ok) ve çökeltme fazlarını içerir. Her bir basamağın hidrolik alıkonma zamanları değişirken çamur yaşı 10 günde sabit tutulmuştur. KOİ, azot (NH4-N, NO3-N) ve fosfat (PO4-P) gideriminde herbir basamağın hidrolik alıkonma sürelerinin etkileri araştırılmıştır. Maksimum nutrient giderimiyle sonuçlanan optimum alıkonma zamanı bulunmuştur. En yüksek gözlenen organik karbon, azot (NH4-N ve NO3-N) ve fosfat (PO4-P) giderme verimleri sırasıyla %96, %87, %81 ve %90 olup 2/1/4,5/1,5/1,5 saatlerde An/Anok/Ok/Anok/Ok işletimiyle sağlanmıştır.
Nutrient removal from synthetic wastewater by sequencing batch operation was studied at different hydraulic residence times. The nutrient removal process was consisted of anaerobic (An), anoxic (Ax), oxic (Ox), anoxic (Ax), oxic (Ox) and settling phases. Sludge age (SRT) was kept constant at 10 days, while hydraulic residence times (HRT) of each phase was varied. Effects of hydraulic residence time of each phase on COD, nitrogen (NH4-N, NO3-N) and phosphate (PO4-P) removal were investigated. Hydraulic residence time of each phase was varied at five different levels and the optimal residence time resulting in maximum overall nutrient removal was determined. The highest observed organic carbon, nitrogen (NH4-N and NO3-N) and phosphate (PO4-P) removal efficiencies were 96%, 87%, 81% and 90%, respectively which was obtained with An/Ax/Ox/Ax/Ox phase residence times of 2/ 1/ 4.5/ 1.5/ 1.5 hours.
