| Abstract | 通过中温半连续厌氧消化实验，考察了果蔬垃圾在不同食微比(0.5、0.75、1.0和1.5)及不同水力停留时间(2、3和4d)下的产氢性能.结果表明，当食微比较低(0.5和0.75)时，各水力停留时间下均不适宜连续产氢，且在水力停留时间为3 d和4 d时容易产生大量甲烷；当食微比较高(1.0和1.5)时，可以实现稳定连续产氢，发酵过程中几乎无甲烷产生.当食微比及水力停留时间分别为1.0及3 d时可获得最佳连续产氢效率，其最高容积产氢量和平均容积产氢量分别为451m L·(L·d)^-1和(186±29)m L·(L·d)^-1，最高挥发性固体产氢率和平均挥发性固体产氢率(以VS计)分别为133 m L·g^-1和(27±5)m L·g^-1，氢气含量可达20%~30%. |
| Other Abstract | Semi-continuous biogas production from fruit and vegetable waste by medium temperature anaerobic fermentation was conducted.Hydrogen production under different food-microorganism ratios(F/M 0.5,0.75,1.0,1.5) and hydraulic retention times(HRT)(2,3,4 d) were investigated.The results show that in the case of a smaller F/M values(0.5 and 0.75),not all HRT stages were conducive to the continuous production of hydrogen,however,they were conducive to producing methane,especially when HRT was 3 or 4 d.Continuous hydrogen production was viable when the F/M ration was relatively higher(1.0 and 1.5),however,this was not conducive to the production of methane,with almost no methane production detected in this process.A F/M of 1.0 and a HRT of 3 d provided the best conditions for continuous hydrogen production from fruit and vegetable waste.Meanwhile,the highest and average daily volume of hydrogen production were 451.2 m L·(L·d)^-1 and(186 ± 29) m L·(L·d)^-1 respectively,whereas the highest and average hydrogen production rate of volatile solids were 133 m L·g^-1 and(27 ± 5) m L·g^-1 respectively.The hydrogen content was 20%-30%. |
