چکیده

پساب رنگی صنایع نساجی در ردیف ترکیبات سمی طبقه‌بندی می‌شود و رهاسازی آنها به طبیعت آسیب‌های شدیدی را به محیط‌زیست وارد می‌سازد. یکی از فناوری‌های جدید جهت تصفیه پساب نساجی، استفاده از پیل سوختی میکروبی می‌باشد. در این پژوهش، سازوکار رنگزدایی پساب حاوی مخلوط دوتایی از رنگزاهای ری‌اکتیو آبی 4 و اسید قرمز 88 در پیل سوختی میکروبی توسط روش‌های طیف‌سنجی چونUV-Vis ، FTIR وCOD بررسی شد. نتایج نشان داد که در روز اول فرآیند رنگ‌زدایی سریع انجام شد که می‌تواند به جذب سطحی زیستی توسط سلول‌های مخمر و سازوکار تجمع زیستی نسبت داده شود. همچنین با بررسی طیفFTIR ، نشانه‌هایی از رنگ‌زدایی از طریق سازوکار تجزیه زیستی در روزهای چهارم و پنجم نیز مشاهده گردید. درصد رنگ‌زدایی نهایی پس از 5 روز بین دو رنگ متفاوت بود و برای اسید قرمز 88، 96 و برای ری‌اکتیو آبی 4 ،85 گزارش شد. درصد حذفCOD  نهایی پساب نیز 87 به دست آمد.

چکیده [English]

The textile dyeing industries' wastewater is classified as a highly toxic composition of toxic compounds, and their release into the environment causes a severe biotic risk to the ecosystem. Microbial fuel cell (MFC) is a promising technology for treating textile wastewater and corresponding electricity generation. This work studied the decolorization mechanism of Reactive Blue 4 (RB4) and acid Red 88 (AR88) dyes in the binary mixture in an MFC using baker's yeast. The decolorization of dyes was analyzed using spectrophotometry methods: UV-Vis, FTIR, and COD measurements. The results showed that the decolorization on the first day was taken place very fast, which can be attributed to biosorption and bioaccumulation mechanisms. Analyzing the FTIR spectrum revealed that the decolorization was also caused by biological decomposition on the fourth and fifth days. The decolorization efficiency for the two dyes differed after the fifth day, and the final decolorization of AR88 and RB4 was 96 % and 85 %. The COD removal of synthetic wastewater from treatment was 87 %.
