摘　　要：采用自制柑橘皮活性炭构建生物活性炭反应器(BAC),并以重庆某垃圾焚烧厂渗滤液生化尾水为处理对象,通过考察柑橘皮BAC反应器在不同水力负荷下对污染物的去除效果,得到反应器运行的最佳水力负荷。当控制进水COD为300～400 mg/L、色度为110～200倍、氨氮为40～60 mg/L、总氮为45～80 mg/L时,柑橘皮BAC反应器在水力负荷为2.25 m3/(m2.d)的情况下能够稳定运行,对COD、色度、NH3-N和TN的平均去除率分别达到75.3%、78.7%、90.6%和48.9%,处理出水水质能够满足垃圾渗滤液排放新标准——《生活垃圾填埋场污染控制标准》(GB 16889—2008)的要求。Biological activated carbon reactor filled with self-made citrus peel carbon was used to treat the biochemical effluent of landfill leachate from a waste incineration plant in Chongqing City. The removal effect of pollutants in the reactor was investigated under different hydraulic loads, and the optimal hydraulic load of the reactor was obtained. When the influent concentrations of COD, color, NH3 - N and TN were controlled at 300 to 400 rag/L, 110 to 200 times, 40 to 60 mg/L and 45 to 80 mg/L respectively, the reactor could achieve steady operation under the hydraulic load of 2.25 m^3/（ m^2 .d）. The corresponding average removal rates were 75.3% , 78.7% , 90.6% and 48.9% respectively. The effluent quality met the Standard for Pollution Control on the Landfill Site for Domestic Waste （GB 16889 - 2008）.
