香蕉皮中温厌氧发酵产沼气性能研究

Biogas Production from Banana Peel by Moderate Temperature Anaerobic Fermentation

摘要: 主要研究了以香蕉皮为原料在中温条件下批量厌氧发酵产沼气的可行性及性能，试验探究香蕉皮原料浓度和接种物浓度这两个因素在中温条件下对批量厌氧发酵产沼气的影响，分别记录产气情况，以及发酵完成后的pH值。结果表明，香蕉皮浓度3%和接种物浓度3%时，产气情况最好，加大接种物浓度会加重酸化，影响产气。

Abstract: Feasibility and performance of biogas production by batch anaerobic fermentation with banana peel as raw material under medium temperature conditions was studied.Effects of banana peel raw material concentration and inoculum concentration on biogas production by batch anaerobic fermentation under medium temperature conditions were investigated.The gas production and pH after fermentation were recorded respectively.Results showed that banana peel concentration of 3%，and inoculum concentration of 3% was the best，and increasing inoculum concentration would aggravate acidification and affect gas production.
