摘　　要：采用外循环生物流化床工艺处理垃圾渗滤液,研究了流化床反应器的启动和连续运行时操作参数改变对出水水质的影响。结果表明,启动阶段历时近1个月,COD去除率在80%左右。系统连续运行时适宜的工艺参数:曝气体积流量为80 L/h,HRT为8 h,进水p H为7.5,在此条件下,COD和NH4+-N去除率分别达89.5%和79.3%左右。The treatment of landfill leachate by using an external biological circulating fluidized bed were studied. The results indicate that during one month of starting, the removal rate of chemical oxygen demand （COD） is about 80%. The optimum operating conditions are achieved： aeration volume flow rate is 80 L/h, HRT is 8 h, pH is 7.5. Under such conditions, the removal rate of COD and NH4^＋-N in leathate is 89.5% and 79.3%.
