Improvement of Energy Conversion Efficiency and Material Utilization Ratio of Anaerobic Digestion of Eupatorium Adenophorum Spreng
摘要
Abstract
In order to get energy conversion efficiency & material utilization ratio of producing methane with Eupatorium adenophorum spreng,we reported a pretreatment of acidification of an-aerobic continuous fermentation for methane production at room temperature.The experimental results showed that the TS and VS of acidification pretreatment for methane production was 1 9 9 L·kg-1 and 240 L·kg-1 respectively,while TS and VS of normal fermentation was 1.72 times and 1.73 times of them.The degradation efficiency of COD of acidification pretreatment was 62.50%,while the other was 44.07%.The utilization of hemicellulose、cellulose and lignin was 18.18%,21.28% and 13.28% of acidification,while is the 1.61,2.00,and 3.16 times of non-acid-ification.The energy conversion efficiency of acidification pretreatment was 42.13%, while it was 1.78 times of normal fermentation,and 1.95 times of the literature value.关键词
