碱性过氧化氢预处理对醋渣厌氧消化性能的影响

利用单因素法研究了碱性过氧化氢预处理过程中的H₂O₂浓度、预处理温度以及预处理时间3个因素对醋渣厌氧消化性能的影响,结果表明,H₂O₂浓度、预处理温度和预处理时间的最优条件分别为4%、40℃和12 h。经实验验证,在最佳联合预处理条件下醋渣厌氧消化累积甲烷产量（基于挥发性固体含量）达302.0 mL/g,生物降解率为70.0%,较未预处理醋渣提升了54.4%。

Impact of alkaline hydrogen peroxide pretreatment on the anaerobic digestion of vinegar residues

The single factor method has been employed to investigate the impact of varying the H₂O₂ concentration, pretreatment temperature, and pretreatment time during alkaline hydrogen peroxide (AHP) pretreatment of vinegar residues prior to their anaerobic digestion. The optimal H₂O₂ concentration, pretreatment temperature, and pretreatment time were found to be 4%, 40 ℃, and 12 h, respectively. Under these optimal conditions, the highest cumulative methane yield was 302.0 mL/g (VS basis) and the biodegradation reached 70.0%, which was 54.4% higher than that for the untreated vinegar residue.
