Performance of hydrogen production in anaerobic baffled reactor(ABR) treating soy protein wastewater

Anaerobic Baffled Reactor(ABR) is a class derived from multi-phase anaerobic reactor stages(Staged Multi-Phase Anaerobic Reactor,SMPA) theory of the third generation of a new anaerobic reactor.To study of anaerobic baffled reactor(ABR) soy protein wastewater treatment efficiency and operating characteristics of the 4 cell room operation of the system of ABR control measures were studied using the effective volume of 42 L four-room frame ABR,MLVSS in the sludge inoculum for the 18.0 g/ L,influent COD concentration of 2 000 mg/L,HRT 48 h,(35 ± 1) ℃ and other conditions(ie OLR1.0 kg/(m3·d)),running through a period of 80 d of the study based on the influent COD concentration was increased organic load(OLR) to change the impact of its processing power,can successfully started in 31 d and reached the initial ABR and stable operation.In addition,rate of 96%,studied different organic load,ABR reactor COD removal efficiency and gas production.On this basis,for the efficient development of ABR equipment,and successfully applied to fermentation technology and bio-hydrogen production of soy protein wastewater treatment under study was provided.
