发酵底物和发酵工艺对沼液中挥发性有机酸的影响
Effects of Fermentation Raw Material and Process on Volatile Organic Acids in Biogas Slurry
摘要
Abstract
In order to reveal the fermentation mechanism of agricultural wastes,biogas slurry from different raw materials and different fermentation process was sampled in two different ecological zones in the cites of Beijing and Nanyang in November 2009. The type and concentration of volatile organic acid (VFA) were analyzed with GC-MS mass spectrometer. The results showed that the content of VFA in the digester of Luying village was lower than that in the digester of Liumi-nying village. The contents of acetic acid and propionic acid in the biogas slurry of Luying village were 1. 86 - 15.16 mg/L and 0. 61-10. 27 mg/L, respectively, which were 0. 35-172. 10 mg/L and 9. 22-11. 05 mg/L for Liuminying village, respectively. In addition, butanoic acid and pen-tanoic acid in the biogas slurry of Liuminying village could be detected, the contents of which were 0. 18-0. 88 mg/L and 0. 03 mg/L,respectively. Therefore, the type and content of VFA in biogas slurry were affected by both raw materials and fermentation process.关键词
