چکیده مقاله :
زمینه و هدف: حذف هیدروکربنهای سنگین و پسابهای بیولوژیکی عموماً پیچیده و دشوار است. هدف از این تحقیق تصفیه پسابهای پالایشگاهی با استفاده از فرآیند ترکیبی فنتون - ماوراءبنفش میباشد.روش بررسی: فرآیندهای اکسیداسیون پیشرفته میتوانند ضمن کاهش بار شیمیایی پساب به کاهش بار بیولوژیکی نیز منجر شوند. در این تحقیق، مطالعه آزمایشگاهی کاهش اکسیژن مورد نیاز شیمیایی(COD) ، اکسیژن خواهی بیولوژیکی(BOD) و روغن و گریس(O & G) با روش فنتون و تابش اشعه ماوراءبنفش انجام شده و اثر شرایط عملیاتی مانند pH، میزان آباکسیژنه، دما و زمان پرتو دهی اشعه ماوراءبنفش بررسی شد.یافتهها: نمونه پساب صنعتی از یکی از شرکتهای پالایشگاهی تهیه شد. مطابق نتایج بدست آمده، شرایط بهینه جهت حذف COD شامل زمان پرتودهی30 دقیقه،pH برابر 3، دمای 35 درجه سانتیگراد، میزان آب اکسیژنه محلول 85 میلیلیتر نسبت به250 میلیلیتر و حذف COD تا 45/74% بدست آمد. همچنین شرایط بهینه جهت حذف روغن و گریس شامل زمان پرتودهی20دقیقه،pH برابر3، دمای 35 درجه سانتیگراد، میزان آب اکسیژنه محلول 85 میلیلیتر نسبت به 250 میلیلیتر و حذف روغن و گریس تا 8/89% بدست آمد. همچنین شرایط بهینه جهت حذف BOD شامل زمان پرتودهی20 دقیقه،pH برابر4، دمای 25 درجه سانتیگراد و میزان آب اکسیژنه محلول 65 میلیلیتر نسبت به 250میلیلیتر از محلول بوده و تحت این شرایط حذف BOD تا 49/82% بدست آمد.بحث و نتیجه گیری: مطالعه آزمایشگاهی کاهش COD ، BOD و O & G با استفاده از واکنش فنتون با آباکسیژنه مورد تحقیق قرار گرفت و اثر شرایط عملیاتی مانند pH ، آباکسیژنه، دما و زمان پرتو دهی اشعه ماوراءبنفش بررسی و در نهایت مشخص گردید که روش فنتون همراه با تابش اشعه ماوراءبنفش برای حذف یا کاهش این مواد آلاینده در پساب پالایشگاهی موثر میباشد.
چکیده انگلیسی:
Background and Objective: The removal of heavy hydrocarbons and biological wastewater is generally difficult. Finding a suitable way to eliminate or reduce these factors is one of the goals of this research.Materials and Methodology: Although there are special processes for removing or reducing the hydrocarbon and biological load of water, but in industrial wastewater containing hydrocarbon, the evaluation of advanced oxidation processes can reduce not only the burden of the wastewater but also reduce the Biological bad effects. Therefore, in the present study, an experimental study of COD, BOD and O & G reduction using Fenton reaction with ultra-violet irridiation has been investigated.Results: A sample of industrial waste from one of the refineries was prepared. According to the results, the optimal conditions for COD removal was observed as follow: irradiation time 30 minutes, pH=3, temperature=35°C, water content=85 ml of oxygen dissolved in water than 250 ml of wastewater and COD removal was observed up to 45.44%. The optimal conditions for removing O&G were: 23 min, pH=3, temperature 35°C, dissolved oxygen content of 85 ml, compared to 250 ml of wastewater. Also O&G was eliminated to 89.8%. The optimal conditions for removing BOD were: the irradiation time is 20 minutes, pH=4, the temperature is 25°C, the soluble oxygen content is 65 ml, compared to 250 ml of the wastewater and the removal of BOD was observed to be 49.82%.Discussion and Conclusion: Laboratory study of COD, BOD and O&G reduction in wastewater was investigated by using Fenton reaction with ultraviolet irridiation. It was found that the Fenton method with ultraviolet irridiation is a suitable method for the removal or reduction of COD, BOD and O&G in refinery wastewater.
