摘　　要：基于垃圾渗滤液浓度高成分复杂的特点,采用改进型上流式厌氧污泥床（Up Flow Anaerobic Sludge Blanket,简称UASB）反应器处理填埋场垃圾渗滤液,并探讨影响厌氧消化的相关因素.当进水原生渗滤液COD浓度在17000～33600 mg/L时,控制进水量,调节停留时间,控制反应器在高容积负荷运行,COD去除率稳定在85.0％～91.8％,去除率与容积负荷呈负相关性;出水COD平均浓度稳定,但是可生化性较差,在高负荷下厌氧反应器产气率较高,而且产气率与有机负荷呈正相关性.Based on the landfill leachate of high wastewater and concent complex＇s feature, the high-strength leachate was treated by the advanced outside circulation UASB （upflow anaerobic sludge blanket）, and the factors influencing the anaerobic digest were discussed. The experimental result showed; When COD of the influent was 17000-33600 mg/L, the COD removal had a negative relativity with volumetric loading rate; the average COD of the effluent was steady, but had a poor biodegradability, under the conditions of high loading rate, the reactor had a high gas producing rate, and it had a positive relativity with volumetric loading.
