预处理茄子秸秆与粪便共消化产甲烷性能

研究了猪粪（PM）和鸡粪（CM）分别与碱性过氧化氢预处理茄子秸秆（PES）在不同比例下共消化产甲烷性能，结果表明：共消化可以缩短反应迟滞期和甲烷日产高峰到达时间，提高累积甲烷产量；当m_PES：m_PM为1：1、1：2和1：4时，累积甲烷产量（基于挥发性固体含量，VS）分别为283.4、338.8 mg/L和359.2 mL/g，较PES单独消化提升了24.7%、49.1%和58.0%，较茄子秸秆（ES）单独消化提升了187.7%、243.9%和264.6%；在m_PES：m_CM为2：1~1：4时，累积甲烷产量较PES单独消化提升3.1%~26.5%，较ES单独消化提升了137.9%~192.0%。

Anaerobic co-digestion of pretreated eggplant stalks and manure

Anaerobic co-digestion has been carried out using eggplant stalks pretreated with alkaline hydrogen peroxide (PES) and two types of manure (pig manure, PM and chicken manure, CM) in varying proportions in order to investigate the effect on methanation performance. The results showed that co-digestion shortened the lag phase and peak times of the daily methane yield and the cumulative methane yield (CMY) increased with higher proportions of PM and CM. At PES/PM mass ratios of 1:1, 1:2, and 1:4 (volatile solid, VS basis), the CMYs were 283.4 mL/g, 338.8 mL/g, and 359.2 mL/g (VS basis), respectively. Compared to the CMY of PES alone, the CMY of the co-digested PES and PM increased by 24.7%, 49.1%, and 58.0% at PES/PM ratios of 1:1, 1:2, and 1:4, respectively. Similarly, in comparison with eggplant stalk (ES) alone, the CMY of the co-digested PES and PM increased by 187.7%, 243.9%, and 264.6% at PES/PM ratios of 1:1, 1:2, and 1:4, respectively. Moreover, co-digestion of PES and CM resulted in increases in CMY of 3.1%-26.5% and 137.9%-192.0%, respectively, compared to PES and ES alone.
