Title Proper : TREATMENT OF THE OIL REFINERY WASTEWATER USING PHOTOCATALYSIS
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Treatment of synthetic oil refinery wastewater employing Ti02 assisted photocatalyticdegradation (PCD) process was studied. Phenol was used as the model pollutant in all theexperiments. Both UV light and Ti02 were required for effective removal of phenol fromthe aqueous phase. For phenol-only studies, near complete phenol degradation was notedwithin 360 min. The removal of phenol in presence of oil, ammonia, lead, cyanide, sulfate,thiosulfate, and mercury, was also studied in order to assess their effect on the phenol PCD.Presence of these species showed varying effects on the PCD trend of phenol. The presenceof oil was generally noted to reduce the overall phenol removal from the contaminatedwater. Similarly, the time required for overall phenol PCD also increased in presence ofboth lead and thiosulfate. However opposite was noted for mercury. For mixed phenol andammonia PCD systems at 10 and 5 ppm concentrations respectively, significant phenolremoval was observed at pH 5, but with insignificant ammonia removal. However at pH 11large ammonia removal was noted with insignificant phenol removal. Overall with anincrease in pH reduced phenol and increased ammonia PCD was noted. Nevertheless theoverall ammonia removal at pH 11 generally decreased with an increase in the ammonia.
