摘　　要：提出了一种产氢和产甲烷的两相厌氧工艺,并在35℃中温条件下进行了实验研究。在分析了20gC0D/L反应器最佳系统有机负荷率(0LR)的条件下,氢反应器的产氢效率最高,为2.0±0.21L/L反应器d;在产甲烷反应器中,剩余有机物和VFAs也可产甲烷,产氢率为1.9±0.3L/L反应器d。最后,能量转换效率可从12.1%(仅氢气生产)提高到91.2%(氢气和甲烷联产)。A two-phase anaerobic process combing hydrogen and methane production was proposed and investigated at laboratoiy-scale at a mesophilic temperature of 35T1.At analyzed optimum system organic loading rate(OLR)of 20 g COD/L reactor·d,hydrogen could be efficiently produced from the hydrogenic reactor with the highest production rate of 2.0±0.21 L/L reactor·d and in the methanogenic reactor,methane could be also prwluced from residual organic matters an(J VFAs with a pmduclion rale of 1.9±0.3 L/L reactor·d.Finally,the energy conversion efficiency can be increased from 12.1%(hydrogen only production)to 91.2%(hydrogen and methane coproduction).
