【 摘 要 】

Problem statement: Hydrogen is a clean energy source. Bio-conversion of biomass togenerate hydrogen has been achieved using anaerobic fermentation of some well-defined materials, inwastewater. No data available on hydrogen yielded from wastewater using inoculum extracted fromIraqi municipal wastewater treatment plant. Approach: This study investigated the effects of substrateconcentration, initial pH and process temperature on biohydrogen production from surgery wastewaterusing anaerobic batch reactor. Batch tests are carried out in a 2.0 L batch reactor under differenttemperatures of 34, 36, 38and 40°C, various initial pH of 4.5, 5.5 and 6.5 and substrate concentrationsof 5, 10 and 15%. The raw seed was compost sludge obtained from municipal wastewater treatmentplant in Baghdad (Al-Restomia plant). The volume of evolved gas was measured at room temperatureby the water displacement method. Results: The maximum hydrogen production 160 mL L^-1 isobtained at an optimum temperature of 38°C, optimum pH of 5.5 and substrate concentration 15%.Conclusion: The results indicated that the use of compost of Al-Restomia plant as a seed in anaerobicfermentation process has given excellent biogas production under applied conditions.
