| 摘 要： | 为了提高蓝藻的资源化利用效率,该研究利用玉米秸秆和蓝藻混合厌氧发酵制备沼气。结果表明,与单一的玉米秸秆或蓝藻发酵过程相比,玉米秸秆和蓝藻混合发酵能够有效促进沼气的生成。当玉米秸秆、蓝藻和接种污泥混合挥发性固体(volatile solid,VS)质量比是2:8:1,产气效果最佳,挥发性固体产气量为687.3mL/g,其中甲烷体积分数达到63.3%。同时该体系液相磷酸盐含量、总碳、总有机碳也最高,表明该系统内发生为了蓝藻的有效降解。研究结果对于农业废弃物和巢湖蓝藻的资源化利用具有一定的意义。

| Abstract: | To enhance the resourcelization of algae biomass, the corn stover was used as the co-digestion substrate for biogas productioin. Results showed that the biogas yield was improved significantly in the co-digestion process compared to that using only corn stalk or algae biomass. When the ratio of corn stalk, algae biomass and sludge was 2:8:1, a maximum value of 687.3 mL/g VS with methane content of 63.3% was achieved. Simultaneously in the aqueous phase, the concentration of phosphate, total carbon and total organic carbon were the highest. Results indicated that digestion efficiency of algae biomass was promoted significantly in this case. |
