  • 摘要: 在UASB反应器中接种好氧污泥培养厌氧颗粒污泥进行启动,研究不同HRT对老龄(13年)垃圾渗滤液对处理效果的影响情况。通过保持进水COD浓度不变、逐步缩短HRT从而提高容积负荷到40 g COD/(L·d)的方法,可以培育出直径为1~3 mm颗粒污泥,最终产气量稳定在100 L/d,甲烷含量在60%~70%之间,COD去除率保持在90%左右,污泥层最底部MLSS为81 g/L。逐步提高HRT依次为6、12、24、48和72 h考察其对处理效果的影响,当HRT为24 h时处理效果最好,COD去除率最高达到35%左右。
    Abstract: Inoculating with activited sludge as the seed material in UASB reactor, the treatment efficiency of municipal landfill leachate (13 years old) was investigated. Keeping the influent COD concentration unchanged as well as a gradual reduction of the HRT,1~3 mm anaerobic granular sludge can be obtained at volumetric loading rate of 40 g COD/(L·d). The final biogas production was 100 L/d and methane content were between 60%~70%, COD removal efficiency remained at 90%, the MLSS of bottom of the sludge layer was 81 g/L. The best treatment effect was at HRT of 48 h comparing the HRT at 6, 12, 24, 48 and 72 h , COD removal rate reached a maximum of 35%.
