牛粪高温干式厌氧发酵产沼气性能试验
Dry Thermophilic Anaerobic Digestion Performance Test of Dairy Manure for Biogas Producing
摘要
Abstract
Dry anaerobic digestion of dairy manure under thermophilic temperature (55℃) for biogas producing was investigated, including the effect of different inoculation ratios on biogas producing, and the changes of biogas and methane producing, pH value, concentrations of ammonia, volatile fatty acid and total alkalinity during digestion. Inoculated dairy manure (the ratio of inoculums and dairy manure was 3: 10) was anaerobic digested 15 days under continuous mechanized mixing (8 r/min) , and total solid biogas production, average daily biogas production, the maximum daily production and the average content of methane reached to 311 mL/g, 2. 73 L/( L · d ) , 5. 23 L/( L · d) (3rd day) and 57.1%, respectively.关键词
