  • 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,研究不同浓度老龄(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20 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60～70 L/d,甲烷含量在50%～70%之间,COD去除率保持在90%左右,污泥层最底部MLSS为50 g/L。逐步提高进水中渗滤液的含量考察其对处理效果的影响,当进水为100%渗滤液时日产气量为500 mL/d、COD去除率仅为10%,表明渗滤液中多为难降解性有机物质。
    Abstract: Treatment of 13 years old of municipal landfill leachate was investigated using UASB reactor which was inoculated with activited sludge as the seed material,1～3 mm anaerobic granular sludge were obtained at volumetric loading rate of 20 g COD/(L·d) by keeping the influent COD concentration unchanged and a gradual reduction of the HRT. The final biogas production are 60～70 L/d with methane content of 50%～70%, COD removal rate remains about 90%, the MLSS of bottom of the sludge layer is 50 g/L. Comparing treatment efficiency with different concentrations of leachate, COD removal rate is only 10%, biogas production is only 500 mL/d when the influent is completely landfill leachate,indicating that most organic matters in the leachate are recalcitrant.
