| 摘 要： | 在接种量20%和35℃条件下,采用2.5 L单相厌氧消化反应器对含固率(TS)为7%、10%、13%的三组高氮污泥进行厌氧消化实验,分析污泥在消化过程中各项指标的变化和产气情况。结果表明,15 d时系统顺利启动,污泥没有产生酸抑制现象,三组实验的单位挥发性固体(VS)产气量达到991 ml/g、1 354 ml/g和441 ml/g。TS 10%组运行较其他两组稳定。

| Abstract: | The anaerobic digestion experiments of high - nitrogen sludge with different total solid contents （7%, 10% and 13% ） were carried out at 35℃ with 20% of inoculation volume. The characteristics of sludge and biogas production were analyzed during the digestion process. The results showed that the digestion system started successfully in 15^th day, and no acid inhibition was observed. The potential capacity of gas production was 991 ml/gVS, 1 354 ml/gVS and 441 ml/gVS respectively for the three groups. The digestion process of the 10% group was more stable than that of other two groups. |
