Bu çaly?mada, asetat ve glikozla beslenen iki anaerobik/anoksik ardy?yk kesikli reaktörde (AKR) anaerobik fosfor salynymyna pH'yn kontrol edilmesinin (6.5, 7.0, 7.5 ve 8.0) ve kontrol edilmemesinin etkisi ara?tyrylmy?tyr. Anaerobik fosfor salynymy, klasik anaerobik/aerobik çamurdakine benzer bir davrany? göstererek pH'yn artmasyyla artmy?tyr. pH kontrol edilmedi?inde, asetat ve glikozla elde adilen anaerobik fosfor salynymy syrasyyla pH 7.5 ve 7.0'den daha çoktur. Elde edilen sonuçlar, pH'yn kontrol edilmemesinin daha uygun olaca?yny göstermektedir.

EFFECT OF pH CONTROL ON ANAEROBIC PHOSPHORUS RELEASE IN ANAEROBIC/ANOXIC SEQUENCING BATCH REACTOR

Öz

In this study, it was investigated to effect of uncontrolled and controlled pH values (6.5, 7.0, 7.5 and 8.0) on anaerobic phosphorus release in two anaerobic/anoxic sequencing batch reactor (SBR) fed with acetate and glucose. It was observed that anaerobic phosphorus release increased with increasing of pH which showed a similar behavior the conventional anaerobic/aerobic sludge. At uncontrolled pH, the anaerobic phosphorus release in acetate and glucose was higher than at pH 7.5 and 7.0, respectively. Obtained results suggest that uncontrolled pH will be more favourable.
