Abstract

Chicken manure wastewaters are increasingly being considered a valuable resource of organic compounds. Screened chicken manure was evaluated as a representative solid organic waste. In this study, electricity generation from livestock wastewater (chicken manure) was investigated in a continuous mediator-less horizontal flow microbial fuel cell with graphite electrodes and a selective type of membrane separating the anodic and cathodic compartments of MFC from each other. The performance of MFC was evaluated to livestock wastewater using aged anaerobic sludge. Results revealed that COD and BOD removal efficiencies were up to 88% and 82%, respectively. At an external resistance value of 150 Ω, a maximum power and current densities of 278 m.W/m2 and 683 mA/m2, respectively were obtained, hence MFC utilizing livestock wastewater would be a sustainable and reliable source of bio-energy generation .

تعتبر مياه الصرف الممزوجة بدَمْن الدجاج مصدرا قيما للمركبات العضوية. دَمْن الدجاج المغربل تم تقييمه كمصدر للنفايات الصلبة العضوية وتم استخدامه كمصدر لإنتاج الطاقة الكهربائية في خلية وقود بايلوجية تعمل بنظام الجريان الافقي وتحتوي على قطبي كاربون (موجب وسالب) يفصلهما غشاء انتقائي. تم تقييم أداء خلية الوقود البايلوجية في معالجتها لمياه صرف تحتوي على دَمْن الدجاج من خلال استخدام حمأة لا هوائية. نتائج الدراسة أظهرت نسب إزالة الاوكسجين الكيمياوي المستهلك والاوكسجين البايلوجي المستهلك بمقدار 88% و 82% على التوالي. بعد ربط حمل خارجي ثابت مقداره 150 اوم، كان مقدار كثافة القدرة القصوى 278 ملي واط لكل متر مربع وكثافة التيار القصوى 683 ملي امبير لكل متر مربع. وبالتالي فان مياه الصرف الصحي الحاوية على روث او دَمْن الدجاج ستكون مصدر مستدام وموثوق بها لتوليد الطاقة الحيوية في خلية الوقود البايلوجية.

Abstract

Present study was conducted at Tigris river, near Wasit Thermal Power Plant (WTPP) in Al Zubiadiyah city to evaluate the impact of discharging domestic sewage during construction period (2010-2016) on water quality of the river; to assess the level at which effluents discharged from WTPP affect the quality of Tigris river water; and to compare the quantity of pollutants in the water with the acceptable limits of Iraqi Standards. Observation recorded during the three months study depicted that the river is polluted in certain areas downstream the river as comparatively higher values of biological oxygen demand (BOD) and chemical oxygen demand (COD) were recorded. The level of total dissolved solids (TDS), dissolved oxygen (DO), chemical oxygen demand (COD), biological oxygen demand (BOD), total hardness, sodium ion, and sulfates (SO4) in the water sample were quite high. With the exception of pH, all other physical-chemical parameters measured are between 100% and 180% higher and have exceeded the maximum permissible limit given by the permissible Iraqi standards. The domestic wastewater is discharged directly to river without any treatment during this period (construction period), there is tendency of these pollutants to persist in the water and its uptake may cause long term health problems when the water is used as drinking water, especially in areas near the point16Thi-Qar University Journal for Engineering Sciences, Vol. 5, No.12014of discharge, since there is an intake of a water compact unit 1 km downstream from the point of discharge (Al-Bokhauder village ), as well as the adverse effects on plants when the contaminated water used for plant irrigation .
