摘　　要：试验以树脂为载体,用自行设计的旋转流厌氧附着膜膨胀床处理高浓度有机废水。经过启动、中等负荷稳定运行及高负荷稳定运行等阶段,成功地培养出高效生物膜颗粒,最高有机负荷达46.4 kg/(m3.d),相应的COD去除率大于80%。在反应器运行过程中采用脉冲示踪法,以LiCl作示踪剂,对反应器的水力流态规律进行了系统的试验研究。研究表明,水力上升流速及气体负荷是影响反应器容积利用率及反应器内固液两相混合程度的重要因素。An innovative swirling flow anaerobic attached growth film expanded bed bioreactor （AAFEB）, using resin particles （20～60 mesh） as the biofilm carrier, was employed for treating a concentrate organic wastewater. The experimen tal program consisted of three phases： start-up, normal loading operation, and high loading operation. The successful start-up resulted in the development of highly effective anaerobic biofilm particles capable of achieving a COD removal efficiency of up to 80% at a high volumetric loading rate （OLR） of up to 46.4 kg/（m^3 · d）. The hydraulic flow pattern in the bioreactor was defined by the pulse input method using LiCl as the tracer. The hydraulic loading and the gaseous loading both affect the utilization of the rector volume and the degree of solid-fluid mixing in the reactor.
