In order to discuss the ability of H2-production and wastewater treatment, a up-flow anaerobic sludge bed (UASB) using a synthesized substrate with brown sugar wastewater was conducted to investigate the hydrogen yield, hydrogen producing rate, fermentation type of biohydrogen production, and the chemical oxygen demand (COD) removal rate, respectively. The results show that when the biomass of inoculants...
The performance and the characteristics of a laboratory scale hybrid anaerobic baffled reactor (HABR) were investigated using synthetic brewery wastewater. The reactor had been operated continuously at 35°C for 109d, with organic loading rate (OLR) increased from 1.2 to 5.6 kg COD/(m3 · d). The results demonstrated that the system was very effective in the treatment of the high-strength wastewater,...
The paper reviewed hydrogen production biotechnology on reactor development and design aspects. Biological hydrogen-producing reactor as acid-producing phase of two-phase anaerobic organism treatment system plays an important role in the following aspects: Reactor was developed as the follow ideas: a. CSTR-type anaerobic fermentation reactor is selected to reduce the substrate concentration in reactor...
Hydrogen is a clean energy carrier which has a great potential to be an alternative fuel. Abundant biomass from various industries could be a source for biohydrogen production where combination of waste treatment and energy production would be an advantage. A study of biohydrogen production using aerobic-pretreated sludge and molasses by anaerobic fermentation in continuous stirred-tank reactor (CSTR)...
Since the effluent from anaerobic reactor of traditional Chinese medicine has high COD and large fluctuate, we took the MBR reactor to treat them at the condition of HRT of 5 h. We investigated the relationship of influent COD, MLSS and COD removal. The results were show as follows: when HRT was 5 h and influent COD less than 3000 mg/L, the effluent COD was less than 30 mg/L which met the need of...
As a new clean energy source and important material, the use and demand of hydrogen are increasing-rapidly. So that bio-hydrogen producing technology moves toward cutting down the operation costs in recent years. Bio-hydrogen production capacity improvement and cost reduction are two key points for industrialization of the process. The paper focuses on: Mixed fermentative bio hydrogen production system;...
