    摘要:

    在中溫（35℃）條件下，分析了不同預(yù)處理方式對(duì)水稻秸稈厭氧發(fā)酵過(guò)程中產(chǎn)氣特性的影響，比較了厭氧發(fā)酵前、后水稻秸稈組分變化的情況，結(jié)果表明：氨化預(yù)處理的秸稈產(chǎn)氣量最大，VS(揮發(fā)性固體)產(chǎn)氣量達(dá)到356.80mL/g，比對(duì)照組高11.70%；各組甲烷質(zhì)量分?jǐn)?shù)的最大值均達(dá)到了70%以上，甲烷含量差異不顯著；水稻秸稈厭氧發(fā)酵后的木質(zhì)纖維素含量均呈現(xiàn)下降的趨勢(shì)，木質(zhì)纖維素的降解率與產(chǎn)氣量成正比，氨化后的水稻秸稈與原水稻秸稈相比，纖維素、半纖維素和木質(zhì)素的降解率分別為28.49%、51.73%和7.13%。

    Abstract:

    Under mesophilic temperature (35℃), the component changes of rice straw before and after anaerobic fermentation were compared. Results show that gas production of amination pretreatment straw is the largest, and VS gas production is 356.80mL/g, 11.70% higher than the control group; the maximum of methane is achieved 70% above, which shows no significant difference between each group. Lignocellulose content presented down trend after anaerobic fermentation, and degradation rate is proportional to the gas production. Compared with the original rice straw, cellulose, hemicellulose and lignin degradation rates of amination pretreatment straw are 28.49%, 51.73% and 7.13% respectively.
