稻草与牛粪混合连续厌氧消化制备生物燃气研究
Continuous Anaerobic Co-digestion of Rice Straw and Cow Manure for Biogas Production
摘要
Abstract
Using rice straw and cow manure ( volatile solid ration 1 : 1 ) as materials, continuous anaerobic co-digestions were carried out to investigate the effects of organic loading rate ( OLR) and temperature on stability and performance. The experimental results showed that, for thermophilic digestion, volumetric biogas production rate ( VBPR) increased with increasing of OLR and the maximum VBPR was 5. 26 m3/(m3'd). The maximum average specific biogas production (SBP) of 489. 6 L/kg was obtained at OLR of 3.6 kg/(m3-d). For mesophilic digestion, biogas production was seriously inhibited by volatile fatty acids (VFAs) at OLR of 12 kg/( m3 -d). During the OLR of 3 ~ 8 kg/( m3o d) , VBPR gradually increased with the maximum of 2. 57 m3/(m3 o d). The maximum average SBP of 440. 0 L/kg was obtained at OLR of 3. 6 kg/( m3od). When the OLR increased to 8 kg/(m3 od) , serious sludge expanding was observed both in thermophilic and mesophilic system.关键词
