Abstract:With the energy conversion efficiency of 2-CSTRs (continuous stirred tank reactor) anaerobic digestion system as the study objectives, hydrogen, ethanol and methane as the target products, at different organic loading rates (OLRs), the ethanol-type fermentation was provided by controlling the available reaction parameters in hydrogen production phase, the treatment water of hydrogen production phase which was recovered ethanol served as the feed of methane production phase, and the energy conversion efficiency of the 2-CSTRs system were dug with different ethanol recovery rates (ERRs). The survey results indicated that energy conversion rate (εT), energy conversion yield (εY) and SDR essentially increased with increasing ERR of 0~50%. Compared with the regular anaerobic digestion system, εT, εY and SDR of the system with ethanol recovery have increased by 32.63%, 17.53% and 12.85% , respectively, with the ERR of 50%.
