  • 摘要: 采用上流式厌氧污泥床（UASB）反应器，以精对苯二甲酸（PTA）废水为处理对象，研究了中温条件下反应器的启动、颗粒污泥的形态和产甲烷活性及微生物群落结构。实验结果表明：采用逐渐提高进水负荷和减少水力停留时间的运行方法，历时近200 d，可实现UASB 反应器的启动。此时，反应器对COD的去除率保持在80%以上，对应的容积负荷也达到4.0 kg·（m3·d）-1以上。反应器内污泥实现颗粒化，颗粒污泥的体积平均粒径为416.53 μm，产甲烷活性为121.2 mL·（g·d）-1 （以VSS计）。颗粒污泥表面存在大量菌胶团，杆菌和丝状菌镶嵌其中。菌胶团有助于微生物的聚集，加速污泥颗粒化过程。Syntrophorhabdus是降解PTA废水中苯类污染物的重要微生物，占细菌量的27.4%，而Methanosaeta则是主要的产甲烷菌，占古细菌总量的67.3%。该研究可为UASB 处理PTA废水的启动提供依据。
    Abstract: The reactor start-up, granular sludge morphology, methane-producing activity and microbial community structure were studied at moderate temperature with pure terephthalic acid (PTA) wastewater as treatment object using up-flow anaerobic sludge bed (UASB) reactor. The result showed that it could realize the start-up of UASB reactor by gradually increasing the inflow load and reducing the hydraulic retention time through 200 d. At this time, the COD removal rate in the reactor remained above 80%, and the corresponding volume load reached higher than 4.0 kg·（m3·d）-1. The sludge in the reactor was achieved granulation, in which the average particle size of the granular sludge and methanogenic activity were 416.53 μm and 121.2 mL·（g·d）-1, respectively. The surface of granular sludge is covered with a large number of zoogloea, embedded with bacillus and filamentous bacteria. The zoogloea was helpful to gather the microorganisms and accelerate the granulation process. Syntrophorhabdus is an important microorganism in the degradation of benzene pollutants in PTA wastewater, accounting for 27.4% of the bacteria, while Methanosaeta is the main methane-producing bacteria, accounting for 67.3% of the total archaebacteria. This study could provide a basis for start-up of UASB treating PTA wastewater.
