In this paper, biochemical hydrogen potential (BHP) tests were conducted to investigate H production from different substrate with acid-treated anaerobic digested sludge at the mesophilic range. The sludge was collected from an anaerobic digester and was subjected to sulfuric acid pretreatments at pH 3 for 24 h. The effects of substrate type (glucose, fructose, and sucrose as carbon source) were investigated in batch experiments. Results showed that substrate degradation rate for all of the substrates was up 95 % and the electron equivalent balance showed good closure for glucose and sucrose. Batch experiments showed that the maximum molar hydrogen yield with glucose, fructose, and sucrose was 3.27, 3.16, and 6.46 mol H/mol of substrate. The maximum cumulative biohydrogen production was 1552, 1487, and 1366 mL and maximum hydrogen production rate was 308, 279, and 275 mL/h for glucose, sucrose, and fructose, respectively. The experimental results suggest that the formation of hydrogen associates with the main aqueous products, i.e., acetate butyrate.
本文进行了生化氢潜力（BHP）测试，以研究在中温范围内经酸处理的厌氧消化污泥利用不同底物产氢的情况。污泥取自一个厌氧消化池，并在pH值为3的条件下用硫酸预处理24小时。在批次实验中研究了底物类型（葡萄糖、果糖和蔗糖作为碳源）的影响。结果表明，所有底物的降解率均高达95%，且电子当量平衡显示葡萄糖和蔗糖的平衡良好。批次实验表明，以葡萄糖、果糖和蔗糖为底物时，最大摩尔产氢量分别为3.27、3.16和6.46摩尔氢气/摩尔底物。葡萄糖、蔗糖和果糖的最大累积生物产氢量分别为1552、1487和1366毫升，最大产氢速率分别为308、279和275毫升/小时。实验结果表明，氢气的形成与主要的水性产物即乙酸盐和丁酸盐有关。
