蜀葵发酵产沼气潜力研究
|
摘要
为解决蜀葵废弃物浪费及污染环境问题,以蜀葵叶子、蜀葵秸秆、蜀葵花籽为原料,分别进行中温(35℃±1℃)条件批量式沼气发酵实验;发酵料液的TS浓度均为6%,沼气发酵实验的运行时间为22 d。实验结果表明:蜀葵叶子、蜀葵秸秆、蜀葵花籽发酵产沼气的潜力分别为397 mL·g~(-1)TS,481 mL·g~(-1)VS; 264 mL·g~(-1)TS,280 mL·g~(-1)VS; 290 mL·g~(-1)TS,314 mL·g~(-1)VS;池容产气率分别为0.39 mL·mL~(-1)d~(-1),0.26 mL·mL~(-1)d~(-1),0.28 mL·mL~(-1)d~(-1),蜀葵叶子的产气潜力明显大于蜀葵花籽和蜀葵秸秆的产气潜力,且蜀葵叶子的甲烷含量也较后两者高,说明蜀葵叶子产出的沼气品位较后两者好。与其他原料相比表明:蜀葵适合用作发酵产沼气的原料,且蜀葵叶子发酵产出的沼气品质较好。
In order to solve the waste and pollution problems of Althaea rosea, biogas fermentation of Althaea rosea's straw, leaves and seed were carried out respectively at(35℃±1℃) adopting batch fermentation. With the TS concentration of 6%, the experiment operated for 22 days. The results showed that the biogas production potential of Althaea rosea's straw, leaf and seed was 397 mL·g~(-1) TS, 264 mL·g~(-1)TS, 290 mL·g~(-1)TS,or 481 mL·g~(-1) VS, 280 mL·g~(-1)VS,314 mL·g~(-1)VS,respectively. The volumetric biogas production rate was 0.39 mL·mL~(-1)d~(-1),0.26 mL·mL~(-1)d~(-1), and 0.28 mL·mL~(-1)d~(-1),respectively. The biogas production potential of Althaea rosea leaf was significantly higher than that of seed and straw, and the methane content of Althaea rosea leaf was also higher than that of the other two, indicating that Althaea rosea leaf had better biogas production quality, could be used as raw material for producing biogas.
