Abstract
To solve the continuous-flow stirred tank reactor (CSTR) hydrogen system has low efficient and waste energy, a 3-compartment anaerobic baffled reactor (ABR), with an effective volume of 27.8L, was adapted and its performing characteristics and hydrogen production efficiency were investigated, using diluted molasses as the material. ABR had higher efficiency and lower energy consumption comparing with CSTR. ABR achieved stable ethanol type fermentation within 26d with 35°C and initial COD of 5000mg/L, and the specific hydrogen production rate was 0.13L/(gMLVSS·d) while that of CSTR under the same conditions was 0.06L/g MLVSS·d. Results showed that ABR was an ideal facility for hydrogen production from organic wastewater fermentation.
