摘要

This paper aims at lowering the temperature for thermal pretreatment (TPT) of antibiotic mycelial residue (AMR) by alkali addition but without significantly worsening subsequent anaerobic digestion (AD) for biogas. Batch TPT and AD experiments were conducted in a bench-scale autoclave and several bench-scale anaerobic digesters, respectively. The results showed that the methane yield (<200 ml.(g VS)(-1)) was visibly lower with lowering pretreatment temperature, compared to that (290 ml.(g VS)(-1)) for TPT at the optimal temperature of 120 degrees C, while it rebounded to 231 ml.(g VS)(-1) when proper amounts of alkali were employed (to adjust the pH of the AMR to 12) for TPT at 80 degrees C. Further analysis indicated that low-temperature alkaline TPT was significantly less energy-consumption compared to only TPT, at cost of small amounts of alkali. It was more convenient and economical to implement AD of AMR in combination with alkaline TPT at mild temperatures for biogas. (C) 2016 Elsevier Ltd. All rights reserved.
