Özet:

 

Biological treatment of pickling industry wastewaters  usually result in low COD removal efficiencies because of plasmolysis  of cells due to high salt content (%3-5) of the wastewater.   Utilization of salt tolerant, halophilic organisms ( e.g, Halobacter  halobium) along with activated sludge culture usually results in  better treatment performances.  Biological treatability of high strength, saline wastewater of  pickling industry was investigated in this study.  Biological  treatment studies were realized in single and two stage activated  sludge systems.  Halobacter added activated sludge culture was used  throughout the studies.  In the single stage activated sludge process, when sludge age was ten  days and the hydraulic residence time was 30h, nearly 97% COD removal  efficiencies were obtained.  In the two stage activated sludge  process, nearly 95% COD removal efficiency was obtained when  hydraulic residence times were qH=20 h in each stage and  sludge ages were qC=10 d.  Kinetic parameters of the system  were determined by using the experimental data obtained with single  stage activated sludge process.
