چکیده

در این تحقیق از فرایند اکسایش الکتریکی در دو راکتور آزمایشگاهی و پایلوت برای حذف رنگ اسید قهوه‌ای 14 استفاده شد. راکتور آزمایشگاهی با حجم 5/0 لیتر مجهز به الکترود پلاتین به‌عنوان آند و الکترود استیل 304 به‌عنوان کاتد بوده و راکتور پایلوت با حجم 9 لیتر مجهز به الکترود استیل 304 به‌عنوان کاتد و آند بود. در این فرایند پارامترهای انرژی مصرفی و بازده آندی بررسی شدند. در راکتور آزمایشگاهی بعد از 18 دقیقه از انجام فرایند حذف رنگ و COD به‌ترتیب برابر 92 درصد و 36 درصد بوده و در راکتور پایلوت بعد از 60 دقیقه از انجام فرایند حذف رنگ و COD به ترتیب 87 درصد و 59 درصد به‌دست آمد. مطالعات سینتیکی بر اساس حذف رنگ و COD نشان داد که در هر دو راکتور آزمایشگاهی و پایلوت سینتیک فرایند از مرتبه صفر پیروی می‌کند.

چکیده [English]

The electrochemical oxidation process was used for the degradation of Acid Brown 14 in both bench and pilot scale reactors. The bench scale one with a working volume of 0.5 L was equipped with platinum plate used as the anode and stainless steel (SS-304) plates as the cathode. The pilot scale reactor had a volume of 9 L and was equipped with SS-304 plates used as both the anode and the cathode. Experiments were run using these reactors to investigate the two parameters of energy consumption and anode efficiency. The bench scale reactor was capable of removing 92% and 36% of the dye and COD, respectively, after 18 min of operation. The pilot scale reactor, however, was capable of removing 87% and 59% of the dye and the COD content, respectively, after 60 min of operation. The kinetic study of both the bench and pilot reactors for dye and COD removals showed that both processes followed a zero order kinetic.
