摘　　要：进行了滇池新鲜蓝藻批量发酵产沼气的研究。研究结果表明,将直接从滇池打捞的蓝藻液静置分层除去60%(V V/)清水后,蓝藻TS为3.39%,V S为93.72%;在平均温度为20.2℃的发酵环境中,发酵66d,蓝藻TS产气潜力为487.3mlg/,VS产气潜力为491.0mlg/,甲烷的平均含量可达64.91%,蓝藻TS利用率为54.02%,VS利用率为57.33%。This paper reported an experiment in which the biogas was produced by the fresh blue algae from Dianchi Lake in batch fermentations for 66 days. The experiment results indicated that the potential of biogas production＇ with blue algae was 487.3 ml/g.TS or 491.0 ml/g.VS. The methane content was 64.91% by average. The TS decomposition rate of algae was 54.2% and the VS one was 57.33%.
