    摘要
  • 摘要: 对水稻、小麦、玉米和高粱4种典型农作物的秸秆进行Ca(OH)2预处理,考察预处理时间和固液比对秸秆酶解产糖的影响,研究预处理秸秆作为固体碳源的反硝化性能。结果表明:与未预处理和水预处理相比,Ca(OH)2预处理秸秆酶解产糖量较高,最优预处理时间为3 d,固液比为1∶30;以Ca(OH)2预处理后的水稻秸秆、小麦秸秆、玉米秸秆和高粱秸秆作为反硝化固体碳源,其反硝化速率分别为0.074、0.056、0.055和0.077 mg/(g·h),是各自未预处理时的211%、215%、239%和197%。

     

    Abstract: Four typical agricultural straws (rice straw, wheat straw, corn straw and sorghum straw) were pretreated by calcium hydroxide, and the effects of pretreated time and solid-to-liquid ratio on enzymatic hydrolysis of straws studied. The denitrification performance was investigated in pretreated straws supported denitrification systems. The results indicated that the higher sugar production was received of calcium hydroxide pretreated straws comparing with raw straws and water pretreated straws. For pretreatment of straws by calcium hydroxide, the optimal pretreatment time was 3 d, and the best solid-to-liquid ratio was 1∶30. The denitrification rates of pretreated rice straw, wheat straw, corn straw and sorghum straw were 0.074, 0.056, 0.055 and 0.077 mg/(g·h), which account for 211%, 215%, 239% and 197% of the raw straws, respectively.
