The continuous process was carried out both by each of the GAC and ozone processes alone and by the combination of the two in order to investigate the synergistic effects of the two modes on COD and color removal in the treatment of vinasse from laboratory ethanol production from cane molasses. The continuous processes were performed at an ozone generation rate of 240mg/h, GAC dose of 100g, and at room temperature (25°C). Color removal efficiency of O3 was higher than its COD removal from vinasse. The COD and color removal efficiencies of the O3 process were about 25% and 74%, respectively. Moreover, GAC/O3 process was found to negatively affect the synergy of COD and color removal efficiency from distillery vinasse. This negative effect decreased by increasing influent pH level. The results indicate that the initial pH has a considerable effect on the three processes investigated.}, keywords = {Vinasse,cane Molasses,Wastewater Treatment,pH,COD}, title_fa = {استفاده از ازن و کربن فعال گرانولی در تصفیه پساب صنایع الکل‌سازی}, abstract_fa = {هدف از این تحقیق، تصفیه پساب کارخانه‌های تولید الکل (ویناس) در فرایند ترکیبی ازن و کربن فعال گرانوله (GAC) در سیستم پیوسته بود. سیستم پیوسته توسط ازن و کربن فعال گرانولی به‌تنهایی و در فرایند توأم GAC/O3 برای تعیین میزان اثر هم‌افزایی GAC و ازن بر حذف رنگ و COD ویناس حاصل از فرایند تولید آزمایشگاهی اتانول از ملاس نیشکر بررسی گردید. آزمایش‌های پیوسته با میزان ازن 240 میلی‌گرم بر ساعت و در دمای محیط و میزان دز GAC معادل 100 گرم انجام گرفت. کارایی ازن در حذف رنگ (74 درصد) بیشتر از حذف COD (25درصد) در شرایط بهینه بود. فرایند  GAC/O3اثر هم‌افزایی بر حذف رنگ و COD ویناس نداشت، بلکه اثر منفی داشت که البته این اثر منفی با افزایش pH ویناس ورودی کاهش یافت. مطالعات نشان داد که تغییر pH اثر زیادی در هر سه فرایند تصفیه دارد.}, keywords_fa = {ویناس,ملاس نیشکر,تصفیه پساب,pH,COD}, url = {https://www.wwjournal.ir/article_1487.html}, eprint = {https://www.wwjournal.ir/article_1487_49dee2b3751efcebd5a4c3749b526f2f.pdf} }
