Abstract:
ان هدف الدراسة الحالية هو ازالة البنزين والفينول والباراكلوروفينول من مياه الصرف الصناعية في مصفى بيجي بعملية الامتزاز بواسطة الكاربون المنشط الحبيبي وامكانية تمثيل العملية بنموذج رياضي.وقد صمم وصنع جهاز مختبري لغرض انجاز الدراسة اخذين بالاعتبار امكاني | The aim of the present study is to remove phenol, parachlorophenol and Benzene from waste water of Baiji refinery by using granular activated carbon. Moreover using the present models to represents the experimental data.A Laboratory scale apparatus is designed and constructed taking into account the most important parameters effecting adsorption. In performing the present study Actual wastewater of Baiji refinery is taken to perform the experimental work.The results indicated that phenol, parachlorophenol and Benzene can be removed completely using granular activated carbon. Also the results indicated that breakthrough and exhaustion time are inversely proportional with the concentration of pollutants and liquid hourly space velocity, while they are directly proportional with the thickness of granular activated carbon. Its found that the Adsorption capacity is directly proportional with the concentration of pollutants and liquid hourly space velocity. The results of this work indicated also the thickness of adsorption zone, which is calculated depending on the result of this study, is directly proportional with liquid hourly space velocity.Application of the most famous available models that are used to represent adsorption phenomena on our experimental data show that only Freundlich model gives excellent agreement.In order to find mathematical model for breakthrough and exhaustion time as a function the most important parameters, an advanced computer program is used.We found two mathematical model for breakthrough and exhaustion time as a function of granular activated carbon thickness, liquid hourly space velocity and the concentration of pollutants. These two models give acceptable agreement with the experimental results.The adsorption capacity for the three pollutants are calculated and found to be directly proportional with liquid hourly space velocity and pollutants concentration.
