| 摘 要： | 垃圾渗滤液为难处理的高浓度有机废水，上流式厌氧污泥床（UASB）工艺被证明是处理该类废水的有效手段。为此，以一系列不同渗滤液浓度的模拟废水作为进水，对逐步启动UASB反应器进行了动态小试，得出了UASB工艺处理垃圾渗滤液的较快速启动方法。结果显示：接种普通厌氧污泥，逐步增加反应器负荷，经过95d的运行，完成启动。此时进水COD质量浓度为5250mg／L，COD去除率为85％，容积COD负荷达8．4kg／（m^3·d），容积产气率为5．0m^3／（m^3·d），反应器底部形成少量颗粒污泥。

| Abstract: | Landfill leachate, a kind of high organic wastewater, has been proved to be treated by UASB effectively. Research on the rapid start-up of UASB is studied using the different concentration of landfill leachate as influent. It shows that the start-up can be completed in 95 days by increasing the loading of the reactor step by step with common anaerobic sludge as the seed sludge. Meantime, the influent COD concentration is 5 250 mg/L, the COD removal rate is 85%, the organic loading COD is 8.4 kg/（m^3 · d）, the net gas yield is 5.0 m^3/（m^3 · d） and some granular sludge is formed at the bottom of UASB. |
