| 摘 要： | 为解决秸秆沼气工程中存在的原料转化率低、消化时间长等问题,选取吸附型添加剂(麦饭石、沸石)作为厌氧消化调节剂,研究比较不同比例的添加剂对消化原料的降解率、产气率等方面的影响.结果表明,吸附型添加剂在消化过程中起到了微生物载体的作用,有利于菌种的富集.添加麦饭石有利于日产气峰值的提前出现,添加10％麦饭石比添加15％麦饭石的日产气效果好,其最高的日产气峰值为1212 mL.添加沸石有利于累计产气量的增加,添加15％沸石比添加10％沸石的累计产气量高50.74％,其最高的净累计产气量为19519 mL.

| Abstract: | In order to solve the problems of low biogas production rate and long fermentation time in straw anaerobic fermentation,medical stone and zeolite were experimented as adsorption-type additives for anaerobic fermentation of cornstalk.The degradation rate,biogas production rate and material energy conversion rate of cornstalk were determined and analyzed.The results showed that the adsorption-type additives could be the carrier of the microorganism during the anaerobic fermentation,which was conducive to the ... |
