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,...
Anaerobic hydrogen fermentation converting carbohydrate-rich wastewater to clean hydrogen energy is a renewable technology for hydrogen production. Applying immobilization technology on biohydrogen production could make the biohydrogen producing system durable and stable in response to organic load impacting and low pH value. This study investigated granular activated carbon to immobilize hydrogen...
A continuous stirred-tank reactor (CSTR) for biohydrogen production using Biohybacterium R3 which is a new anaerobic hydrogenogens bacteria. The point was to assess the start-up and continuous operation characteristics. It was found that at pH of about 4.5, the COD concentration of 6000 mg·L-1, and a hydraulic retention time (HRT) of 8h, a hydrogen producing microbial community could be adapt on the...
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...
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...
