摘　　要：利用河底污泥,以葡萄糖为基质,在pH值为5.0～5.2,温度为35℃,水力停留时间为68h的条件下,实现了连续厌氧生物产氢。结果表明:当容积负荷为36kgCOD·m-3d-1时,产气中主要含有氢气和二氧化碳,其中H2约为52.3%,反应器的容积产氢率最高达6.7L·L-1d-1,基质产氢率为1.3～1.4mol·mol葡萄糖-1;液相中主要末端产物为乙醇、乙酸、丁酸,三者摩尔比约为1∶1∶0.6,另有少量丙酸。s: Using river sediments as seed sludge, at the condition of pH 5.0～5.2, temperature 35 ℃, HRT 6～8 h, and with glucose as substrate, a steady anaerobic bio-hydrogen production was obtained in a lab-scale reactor successfully. The results showed that: at organic loading rate of 36 kgCOD·m^(-3)d^(-1) , H_2 content in the product gas was about 52.3%, the highest hydrogen production was 6.7 L·L^(-1) d^(-1),the specific hydrogen prodution was 1.3～1.4 mol ·mol-glucose^(-1). The effluent mainly contained ethanol,acetate, butyrate and their molar proportion was 1∶1∶0.6.
