| 摘 要： | 针对蓝藻厌氧发酵过程中极易上浮分层影响产沼气效率的问题,采用批量发酵工艺,研究悬浮载体对蓝藻厌氧发酵产沼气过程的影响.结果表明,添加聚乙烯(PE)载体,使累积产气量提高13.7%(P<0.01),蛋白酶活性分别提高8.6%(P<0.05),叶绿素a消减率从21.4%提高到29.8%(P<0.05),COD消减率从41.2%提高到46.2%,挥发性脂肪酸含量也有明显提升.说明使用悬浮载体可显著提高蓝藻的厌氧发酵效率.

| Abstract: | According to the fact that blue algae are easily up-floating and stratified during anaerobic fermentation,thereby decreasing biogas-producing efficiency,suspended carrier was applied and its influence on anaerobic digestion process of blue algae was studied using the batch fermentation technology.After addition of suspended PE earriem,eumula-tive biogas production was increased by 13.7%,proteinase activity Was increased by 8.6%,eliminating rate of chloro-phyll-a rose from 21.4% to 29.8%,eliminating rate of COD was enhanced from 41.2% to 46.2%,and total volatile fatty acids was also increased obviously.The results indicated the addition of suspended carrier promoted the anaerobic digestion of blue algae. |
