摘　　要：采用经驯化、碱处理后的活性污泥,分别以葡萄糖、蔗糖、壳寡糖、淀粉为基质,在不同初始pH值、不同温度条件下,采用厌氧发酵处理并获取氢气气体.结果表明,反应温度和初始pH值均对污泥厌氧产氢具有显著影响,最佳温度为35℃,最佳初始pH值为5.5.以壳寡糖、淀粉为基质时,累计产氢量较低;以蔗糖为基质时,可获得最大的产氢量为238.5mL,气体中氢气含量约为95%.This paper introduces the anaerobic fermentative production of hydrogen from active sludge domesticated and alkalized with glucose,sucrose,chitooligosaccharides,and starch as substrates at different temperatures and different initial pH values.The results showed that the optimal temperature was 35 ℃,and the optimal initial pH value was 5.5.With chitosan and starch as substrate,the total production of hydrogen was lower;with sucrose as substrate,the maximum of hydrogen was 238.5mL,and the hydrogen amount in the gas was about 95%.
