摘　　要：为对比2种旋转式生物膜法反应器生物转盘和生物转笼处理含盐工业废水的效能,以榨菜厂综合排放废水为处理对象,通过监测现场小试规模的2种反应器的启动和运行,对比了两者的挂膜特点和对污染物去除的效果;以COD和NH_3-N去除率均超过80%,且生物膜厚度超过2 mm作为反应器启动成功的标准。结果表明,在启动阶段两者挂膜速度差异不大,分别为35 d和31 d;在运行阶段,生物转笼在相同面积负荷下,对NH_3-N和有机物的去除效果更佳,且抗冲击负荷能力更强。因而,生物转笼是一种比生物转盘更具潜力的生物膜反应器。In order to compare the effectiveness of two rotating biofilm reactors for salty industrial wastewater treatment, the wastewater from mustard tuber factory was used as process object. The features and pollutant removal efficiency of two reactors at starting phase and operation phase were measured and compared. When the removal rates of organic matter and NH3-N were both more than 80%, and the thickness of biofilm was more than 2 mm, it was the metrics of starting phase success. The results showed that, there was no significant difference of biofilm culturing rate between the two reactors at the starting phase（35 d and 31 d, respectively）, but the rotating biological cage had higher removal efficiency of organic matter and NH3-N under same area load at the operation phase. Moreover, it also had stronger shock resistance capacity. Therefore rotating biological cage had a greater advantage over the rotating biological contactor.
