| پساب صنایع نوشابهسازی دارای ﻣﻘﺎﺩﯾﺮ ﺑﺎﻻﯼ ﺗﺮﮐﯿﺒﺎﺕ ﺁﻟﯽ است که ﺭﻭﺵﻫﺎﯼ ﺗﺼﻔﯿﻪ زیستی ﺩﺭ ﺍﯾﻦ ﺯﻣﯿﻨﻪ ﺑﺴﯿﺎﺭ ﻣﺘﺪﺍﻭﻝ است. با اعمال روشهای کارآمد جهت تصفیه پساب صنایع نوشابهسازی، میتوان زمینه مصرف پساب تصفیه شده را در جاهای دیگر فراهم نمود. هدف کلی از تحقیق حاضر بررسی کارایی فرآیند لجن فعال با هوادهی گسترده و برگشت لجن جهت کاهش میزان COD پساب صنایع نوشابهسازی است. جهت ارزیابی در ابتدا از یک مخزن 20 لیتری به صورت کاملا بیهوازی استفاده شده که پساب ساختگی از آن به پایلوت منتقل شده است. میزان بارگذاری آلی از مقدار kg COD/m3.day 1/03 تا kgCOD/m3.day 1/93 افزایش یافته است و در این تحقیق جهت سنجش میزان آلودگی پساب صنایع نوشابهسازی از پارامتر COD استفاده شده و سیکل کاری 24 ساعت بوده است. همچنین پارامترهای زمان ماند هیدرولیکی، دما و pH نیز مورد اندازهگیری قرار گرفتند. نتایج حاصل شده از فرآیند مذکور نشان داد که با بارگذاری آلی نهایی به میزان kg COD/m3.day 1/93 راندمان حذف برابر 90 درصد گردید، که بخشی از راندمان حذف (20 تا 30 درصد) مرتبط با مخزن بیهوازی استفاده شده در ابتدا پایلوت است. با بررسی زمان ماندهای هیدرولیکی 6، 12، 18 و 24 ساعت، بیشترین راندمان در زمان ماند 24 ساعت به دست آمده و در روند تحقیق میزان pH بین 7 تا 9 و دما در محدوده مزوفیلیک قرار داشته است. لذا میتوان نتیجه گرفت که فرآیند لجن فعال با هوادهی گسترده و برگشت لجن در تصفیه پساب صنایع نوشابهسازی با بار آلی متوسط موثر است. | ||

| The effluent of the beverage industry has a higher yield, which is biological. Locations The overall objective of this study is to evaluate the efficiency of the activated sludge process with extensive aeration and sludge return to reduce the COD of beverage industry effluents. For evaluation, a 20-liter tank was completely used anaerobically, from which the artificial effluent was transferred to the pilot. The organic load increased from 1.03 kgCOD/m3.day to 1.93 kgCOD/m3.day. In this study, the COD parameter was used to measure the pollution of the beverage industry effluent and its working cycle was 24 hours. Hydraulic retention time, temperature and pH were also measured. The results of this process showed that with a final organic load of kg COD/m3.day of 1.93, the removal efficiency was 90%, which is part of the removal efficiency (20 to 30%) of the anaerobic tank used in the first pilot. By examining the hydraulic retention times of 6, 12, 18 and 24 hours, the highest efficiency was obtained in the retention time of 24 hours and in the research process, the pH was between 7 and 9 and the temperature was in the mesophilic range. Therefore, it can be concluded that the process of activated sludge with extensive aeration and sludge return is effective in the treatment of effluents of beverage industries with medium organic load. | ||
