Abstract (2. Language): 
In this study, coagulation/flocculation-sequencing batch reactor (SBR) method was applied to a strong slaughterhouse wastewater. The raw slaughterhouse wastewater was first allowed to settle. The optimum removal efficiency in coagulation/flocculation process was obtained at 6 for pH, 600 mg/l for coagulant (aluminium sulphate) and 20 mg/l for anionic polyelectrolyte. Effluent concentrations after the coagulation/flocculation treatment were 35 mg/l for TSS (removal efficiency, %95) and 9 mg/l for oil-grease (removal efficiency, %90) and the discharge standard values were obtained. SBR was operated at three hydraulic retention times (HRTs) of 1, 2 and 3 days and effluent COD concentration was 150 mg/l (removal efficiency, %87), 120 mg/l (removal efficiency, %90) and 80 mg/l (removal efficiency, %93), respectively. A 1-day HRT was found sufficient to get discharge standard value for COD. The results show that coagulation/flocculation-sequencing batch reactor (SBR) method is an effective method for strong slaughterhouse wastewater and its effluent concentration values were lower from discharge standard values.

Abstract (Original Language): 
Bu çalışmada, yüksek organik kirliliğe sahip mezbaha atıksuyunun arıtımında koagülasyon/flokülasyonardışık kesikli reaktör (AKR) yönteminin etkinliği araştırılmıştır. Ham mezbaha atıksuyu öncelikle basit olarak çökeltilmiştir. Çökeltilmiş mezbaha atıksuyuna uygulanan koagülasyon/flokülasyon yönteminde optimum değerler pH değeri için 6, koagülant (alüminyum sülfat) dozu için 600 mg/l ve anyonik polielektrolit için 20 mg/l olarak bulunmuştur. Koagülasyon/flokülasyon prosesi sonunda AKM konsantrasyonu 35 mg/l (giderme verimi, %95) ve yağ-gres konsantrasyonu 9 mg/l’ye (giderme verimi, %90) azaldığından deşarj standart değerleri sağlanmıştır. Biyolojik arıtım için kullanılan ardışık kesikli reaktör (AKR) ise; 1, 2 ve 3 günlük hidrolik bekleme zamanın (HRT)’da işletilmiştir ve çıkışında KOİ değerleri sırasıyla 150 mg/l (giderme verimi, %87), 120 mg/l (giderme verimi, %90) ve 80 mg/l (giderme verimi, %93) olarak bulunmuştur. 1 günlük hidrolik bekleme zamanının KOİ parametresi bakımından deşarj standart değerini sağlamaya yeterli olduğu bulunmuştur. Bu çalışmanın sonunda, koagülasyon/flokülasyon-ardışık kesikli reaktör (AKR) yönteminin kuvvetli karakteristiğe sahip mezbaha atıksularının arıtımında etkili olduğu ve mevcut deşarj standartlarını sağladığı bulunmuştur.
