Abstract
Bu çalışmada Bursa ilinde faaliyet gösteren ve sürekli yönteme göre zeytin ve zeytinyağı üretimi yapan bir tesisten kaynaklanan karasuyun asit kraking+fenton prosesiyle arıtılabilirliği araştırılmıştır. Yapılan Jar Testleri sonucunda optimum pH değerinin 3 ve optimum koagülant dozlarının 6000 mg/L FeSO4 ve 5000 mg/L H2O2 olduğu belirlenmiştir. Bu dozlarda KOİ 112000 mg/L’den 4800 mg/L’ye, fenol ise 7360 mg/L’den 29 mg/L’ye indirilmiş, bu değerlerdeki giderme verimleri ham suya göre sırasıyla %96 ve %99,6 oranlarında elde edilmiştir. Zeytin karasuyunun asit kraking+fenton prosesi yardımıyla arıtılabilirliğine yönelik maliyet analizinin de yapıldığı bu çalışmada, oldukça yüksek giderim verimliliğinin elde edilmesine rağmen, SKKY’nde verilen kanalizasyona deşarj kriterine (KOİ=4000 mg/L) ulaşılamamıştır. Bu nedenle fenton prosesinden çıkan karasuyun evsel atıksularla birlikte arıtılabilirliğine yönelik deneysel çalışmaların yapılması gereklidir.
In this study, treatability of olive mill wastewater from a plant which produces olive and olive oil according to continuous method in Bursa has been investigated by acid cracking&fenton process. It has been determined that optimum pH is 3, optimum FeSO4 and H2O2 doses are 6000 mg L-1 and 5000 mg L-1, respectively after the Jar Tests. In these doses, KOI and phenol have been reduced from 112000 mg L-1 to 4800 mg L-1and from 7360 mg L-1 to 29 mg L-1, respectively and removal efficiencies of COD and phenol have been obtained according to raw wastewater 96% and 99,6%, respectively. Also, the cost analysis has been calculated for olive mill wastewater treatability by acid cracking&fenton process in this study. Although olive mill wastewater could be treated quite efficiently by acid cracking+fenton process, it hasn’t been reached to discharge criteria for environment (COD=4000 mg L-1) given in Water Pollution Control Regulations. Therefore, it has been thought that application of treatment with domestic wastewater after fenton process can be quite suitable for olive mill wastewater treatment.
