摘　　要：以模拟的城镇生活垃圾为底物,在发酵试验起始阶段向反应体系通入不同浓度氧气(0,5,10,20 m L O2/g VS),探究微氧处理对两相发酵联产氢气甲烷的影响。研究表明,通入5 m L O2/g VS的试验组获得了最高的氢气产量(72.23 m L/g VS),较未处理组提高了45.51%;虽然通入5 m L O2/g VS的试验组也获得了最高的甲烷产量(380.35 m L/g VS),但相比其他试验组并无明显提高。从整体来看,通入5 m L O2/g VS的试验组获得了最高的VS降解率(75.66%)和最高的能量回收率(72.76%),较未处理组分别提高了5.70%和5.33%。试验表明,适量的微氧处理(5 m L O2/g VS)可以提高城镇生活垃圾两相发酵联产氢气甲烷的产能效果。In order to investigate the effect of micro-aeration on the co-production of hydrogen and methane from domestic organic waste, different concentrations of oxygen（0,5,10,20 m L O2/g VS） were supplied at the initial stage of the two-phase fermentation. Results showed that the maximum hydrogen yield（72.23 m L/g VS）was obtained at the oxygen load of 5 m L/g VS, which was 45.51% higher than that of sample without micro-aeration. Though the maximum methane yield（380.35 m L/g VS） was also obtained at the oxygen load of 5 m L/g VS, it had no significant difference with other groups. Overall, the highest VS degradation rate（75.66%） and energy recovery rate（72.76%） were simultaneously obtained at the oxygen load of 5 m L/g VS, which were5.70% and 5.33% higher than those of sample without oxygen, respectively. Micro-aeration（5 m L O2/g VS） at the initial stage of the two-phase fermentation was an effective approach to improve the performance of the co-production of hydrogen and methane by the two-phase fermentation.
