چکیده

دراین پژوهش، پارامترهای موثر در تولید بیوگاز از پسماند های غذایی به همراه کود دامی موجود در منطقه و افزودنی‌های ارگانیک بررسی شده است. پسماند‌های غذایی از رستوران دانشگاه جمع آوری و با کود دامی(گاوی) با نسبت های مختلف 1:1، 1:2، 1:3، 3:1 درمقیاس آزمایشگاهی‌ در محدوده دمایی ترموفیلی(55-60 درجه سانتی گراد) به مدت 15روز قرار داده و حجم گاز تولیدی اندازه‌گیری شد. نتایج حاصل از تولید گاز نسبت 1:1 کود دامی و پسماند غذایی، بالاترین میزان گاز تجمعی با حجم 5لیتر را نشان داد. با افزودن 10 گرم افزودنی شیمیایی سیلیکا ژل و گیاه رزماری ، ،پوست گردو،پوست موز و گوجه به مخلوط فوق به ترتیب میزان گاز تجمعی با 4/24%،7/2 %،3/2 %،9/1 %، 6/ % درصد حجمی افزایش را نشان داد. در طول دوره هضم، تغییرات pHنشان داد که بالاترین میزان حجم گاز در pH خنثی تولید شد.و ‌‌استفاده از پوست گردو باعث تثبیت pH در فرایند شد. همچنین با اندازه‌گیری خواص ترموفیزیکی(مواد جامد،مواد فرار،رطوبت، درصد خاکستر) مخلوط پسماند غذایی با کود دامی ظرفیت تولید بیوگاز 43/0 درصد برآورد شدکه نشان دهنده ظرفیت بالای پسماند غذایی برای تولید بیوگاز می‌باشد. بر اساس نتایج بدست آمده ازراکتور پرتابل آزمایشگاهی برروی مخلوط بهینه پسماند های غذایی وکود دامی آنالیز انرژی در آن بررسی شد.

چکیده [English]

An experimental investigation has been done on the effective parameters of biogas production from the mixture of food waste (FW), cow manure and organic additives. The samples of FW were collected from the university restaurant and they have mixed with the cow manure (CM) with different ratios of (FW/CM) 1:1, 1:2, 1:3, and 3:1 in a one liter polymeric bottle. These bottles embedded in a hot water bath at a thermophilic temperature of 55-60 °C in the period of 15 days and the volume of produced biogas was measured. The results were shown that with the ratio of 1: 1 the highest volume of gas was collected (5 liters). Then 10 grams of chemical additive of silica gel and organic additives like rosemary plant, walnut shells, and banana and tomato skin were added to the optimum selected ratio of digester. The produced biogas was increased 24.4%, 7.2%, 2.3%, 1.9% and 6.6% by volume respectively in compare with that of optimum based mixture. During the digestion process, it was found the highest volume of biogas was collected when the pH of the mixture was in neutral range (7) and the use of walnut shells resulted to pH stabilization in the process. Measuring physical properties (total solids, volatile matter, moisture content, and ash content), for the mixture of food waste and manure were shown the high capacity of food waste to convert to biogas based on the laboratory experiments.
