Farklı organik ve hidrolik yüklemelerde hareketli yatak biyofilm reaktörlerin (HYBR) performansı

Öz:
Hareketli Yatak Biyofilm Reaktör (HYBR)’ler aktif çamur prosesinin bir modifikasyonudur. Proses, sentetik taşıyıcı malzeme ilave edilmiş havalandırma havuzu ve geri devirsiz çökeltme havuzundan oluşmaktadır. Bu çalışma kapsamında, HYBR prosesi tanımlanmış, prosesin farklı hidrolik ve organik yüklemelerdeki performansı organik madde ve azot giderimi ile çamur üretimi açısından incelenmiştir. 2 L’lik havalandırma havuzunun boş hacminin % 50’si Kaldnes K1 ile doldurulmuş ve sentetik atıksu ile beslenmiştir. HYBR performansı üzerine hidrolik yüklemenin etkisi 4, 8 ve 12 saat hidrolik alıkonma sürelerinde 500 mg/L KOİ içeren sentetik atıksuyun reaktöre beslenmesi ile, organik yüklemenin etkisi ise 8 saat hidrolik alıkonma süresinde 500, 1000, 2000, 4000, 8000 mg/L KOİ içeren sentetik atıksuyun reaktöre beslenmesi ile izlenmiştir. Hidrolik yüklemelerde, 500 mg/L KOİ içeren sentetik atıksuyun arıtımında 4 saat hidrolik alıkonma süresinin ortalama % 94.6 KOİ giderim verimi ile yeterli olduğu tespit edilmiştir. Bununla birlikte, artan hidrolik alıkonma ile nitrifikasyonda artış gözlenmiştir. Çıkış nitrat azotu sırasıyla 6,12 mg/L, 10,99 mg/L ve 16,6 mg/L olarak ölçülmüştür. Organik yüklemelerde, organik yükleme arttıkça organik madde giderimi azalmış, 6 g KOİ/$m^2$.gün ‘ün üzerinde nitrifikasyon gözlenmemiştir. Ortalama KOİ giderim verimleri organik artan yüklemelerde sırasıyla % 95.1, % 94.9, % 89.3, % 68.7, % 45.2 olarak hesaplanmıştır. Çamur oluşumu, 500 mg/L KOİ girişinde 0.12 kg AKM/kg KOİ olarak elde edilmiş ve artan organik yükleme ile artmıştır.

Performance of Moving Bed Biofilm Reactors (MBBR) at Different Organic and Hydraulic Loadings

Öz:
Moving Bed Biofilm Reactor (MBBR) is a modification of activated sludge process. The process has an aeration tank with synthetic carrier element and no sludge recycling from the clarifier. In this study, MBBR process is defined and its performance under different hydraulic and organic loadings was revealed as organic matter removal, nitrogen removal and sludge production. Aeration tank with 2 L volume was filled with the Kaldnes biomedia K1 at 50% of the volume of empty reactor and fed continuously with synthetic wastewater. The effect of hydraulic loadings on MBBR was studied with feeding synthetic wastewater that consist of 500 mgCOD/L at 4, 8 and 12 hours hydraulic retention times whereas the effect of organic loadings on MBBR was studied by feeding synthetic wastewater containing 500, 1000, 2000, 4000 and 5000 mgCOD/L as a function of organic load at 8 hour hydraulic retention time. At the hydraulic loads, 4 hour hydraulic retention time was founded enough for treating wastewater that consist 500 mgCOD/L with 94.6 % average COD removal. However, by increasing hydraulic retention time nitrification increased. Effluent nitrate‐nitrogen was measured 6.12 mg/L, 10.99 mg/L ve 16.6 mg/L at 4, 8 and 12 hours, respectively. At the organic loads, when organic loading was increased from 6 to 96 g COD/$m^2$.d, organic matter removal decreased. Nitrification became insignificant at organic loading rate of 6 g COD/m2.d. Average COD removal at the organic loadings were calculated as 95.1 %, 94.9 %, 89.3 %, 68.7 %, 45.2 % at 6, 12, 24, 48, 96 g COD/$m^2$.d organic loadings, respectively. Resultant sludge production was equal to 0.12 kg TSS/kg totalCOD for influent totalCOD of 500 mg/L and increased when organic loading was increased.
