Abstract    Recently developed man-made structures have caused environmental pollutions, and unfortunately, in spite of the deteriorating affairs and repeated warnings by scientists and experts, the degree of contamination is increasing considerably. One of the natural sources undergoing changes is the coasts. It is mainly due to human activities which have led to a change in the quality and quantity of sediments. These regions can be contaminated by a variety of hazardous pollutants such as heavy metals and hydrocarbons. In this work, a combination of electrokinetic and MFC process was used for Cr removal from contaminated sediments. According to the obtained results, a maximum power density and current of 1.06 W/m3 and 52.05 A/m3 were achieved during the process. Given the presence of chromium in the catholyte, it can be concluded that the chromium migration from sediment sample to the cathode chamber has been taken. In addition, the maximum Cr measured in catholyte was 0.056 mg/l. Overall, the results confirmed the high efficiency of the proposed cell for contaminant removal from sediments.

چکیده   

توسعه اخیر ساخته های دست بشر، موجبات آلودگی محیط زیست را فراهم آورده است و متاسفانه علیرغم هشدارهای کارشناسان و دانشمندان این حوزه میزان آلودگی به شکل چشمگیری افزایش یافته است. یکی از این منابع طبیعی دستخوش تغییرات سواحل است که عمدتا به دلیل فعالیتهای انسانی منجر به تغییر کیفیت و کمیت رسوبات گردیده است. این مناطق توسط انواع آلاینده های خطرناک همچون فلزات سنگین و هیدروکربنهای نفتی آلوده شود. در تحقیق حاضر از فرآیند ترکیبی الکتروکینتیک و پیل سوختی میکروبی برای حذف کروم از رسوبات استفاده شده است. با توجه به نتایج به دست آمده بیشترین چگالی توان 06/1 وات برمترمکعب و بیشترین چگالی جریان 05/52 آمپر بر مترمکعب در طی فرآیند حاصل گردید. با توجه به حضور کروم در محلول کاتولیت، می-توان نتیجه گرفت که مهاجرت فلز کروم از نمونه رسوب به درون محفظه کاتد انجام شده است. علاوه بر آن حداثر میزان کروم بدست آمده در نمونه کاتولیت 056/0 میلی گرم بر لیتر بوده است که حاکی از کارایی بالای سلول پیشنهادی برای حذف آلودگی از رسوب می باشد.
