　　研究了不同水力停留时间（ HRT）对两相厌氧发酵产酸和产气特性的影响，结果表明：产酸相的最佳水力停留时间为3 d，挥发酸总量最高为13701．67mg/L，乙酸和丁酸之和的百分含量在80％以上，属于丁酸型发酵类型；产甲烷相的最佳水力停留时间为6d；37d的累积产气量为926．51 L，甲烷百分含量达到73％左右；对于连续补料发酵，在产酸相和产甲烷相反应器有效容积相同的情况下，产酸罐和产甲烷罐的个数比为1：2。

The influence of hydraulic retention time (HRT) on characteristics of two-phase anaerobic fermentation is studied.The results show that: the optimal HRT of acidification phase is 3d, and the highest volatile acid content is13 701.67mg/L, butyric acid type fermentation is observed because the percentage of acetic acid and butyric acid is more than 80%.The optimal HRT of methanogenic phase is 6d, the cumulative gas production of 37d is 926.51L, and the percentage of CH4 reaches around 73%.For continuous feeding fermentation, with the same effective volume of acidi-fication and methanogenic reactor , the number ratio of acidification and methanogenic reactor is 1:2.
