چکیده مقاله :
در این مطالعه، فرآیند بیولوژیکی هوازی به روش بیوراکتور بستر محترک (MBBR) جهت تصفیه فاضلاب صنایع شوینده مورد بررسی قرار گرفت. میانگین COD و LAS در فاضلاب خام به ترتیب mg/L 10231 و mg/L 210 بود. در این مطالعه، سه غلظت مختلف LAS ( mg/L 210، 500 و 1000 ) به منظور تعیین کارایی کل سیستم در حذف COD و LAS استفاده شد. نسبت BOD5/COD پس از پیش تصفیه از 2/0 در فاضلاب خام به 45/0 افزایش یافت. در سیستم MBBR در راکتور 1 با 36 ساعت زمان ماند هیدرولیکی (HRT) بالاترین راندمان حذف به ترتیب برابر 41/93 % و 95 % برای COD و LAS بدست آمد. در راکتور 2 نیز با شرایط مشابه با HRT برابر 36 ساعت، بالاترین راندمان حذف برای COD و LAS به ترتیب برابر 20/94 % و 99/99 % حاصل شد. با تغییرات مقدار هوای تزریقی از L/min 30 به L/min 50 و سپس L/min 70، راندمان حذف در مقدار تزریق هوا به L/min 50 افزایش یافت. بررسی‌های سرعت بارگذاری بار آلی (OUR) نیز کاهش مقدار ویژه مصرف اکسیژن از حدود mg O2/gr MLSS .hr 11 در ابتدای دوره بهره برداری به حدود mg O2/gr MLSS .hr2 در انتهای دوره را نشان داد. این مطالعه نشان داد که با فرآیند MBBR می تواند استانداردهای خروجی محیط زیست برای صنایع شوینده را تامین کرده و به عنوان روشی کارآمد در تصفیه پساب صنایع شوینده بکار رود.
Abstract In this study, the aerobic biological process was investigated by the moving bed bioreactor (MBBR) method for wastewater treatment of detergent industries. The mean of COD and LAS in raw wastewater were 10231 mg/L and 210 mg/L, respectively. In this study, three different concentrations of LAS (210, 500, and 1000 mg/L) were used to determine the efficiency of the whole system in removing COD and LAS. The BOD5/COD ratio increased from 0.2 in raw wastewater to 0.45 after pretreatment. In the MBBR system in reactor 1 with 36 hours of hydraulic rate time (HRT), the highest removal efficiencies of 93.41% and 95% were obtained for COD and LAS, respectively. In Reactor 2 with similar conditions to HRT of 36 hours, the highest removal efficiencies for COD and LAS were 94.20% and 99.99%, respectively. By changing the amount of injected air from 30 L/min to 50 L/min and then 70 L/min, the removal efficiency in the amount of air injected about 50 L/min was increased. Organic charge loading (OUR) studies also showed a reduction in specific oxygen consumption from about 11 mg O2/gr MLSS.hr at the beginning of the operation period to about 2 mg O2/gr MLSS.hr at the end of the period. This study showed that the MBBR process, can meet the environmental output standards for the treatment of detergent industry wastewater and be used as an efficient method in detergent industry wastewater treatment.
