摘　　要： 通过天然浮石和塑料多孔空心球而制成复合式多孔矿物载体应用于厌氧固定床反应器中,研究反应器挂膜性能,以及处理生活污水、啤酒废水效果,应用扫描电镜观察生物膜微生物相的形态结构。结果表明,反应器挂膜69 d后COD去除率稳定在70%以上,初次启动成功;处理生活污水中平均COD去除率为61.72%;处理啤酒废水中COD去除率高于88%,生物膜中微生物优势种群为杆菌和球菌。 A compound porous mineral carrier made from natural pumice and plastic porous hollow ball was applied in the anaerobic fixed bed reactor to study the performance of biofilm culturing,treat the domestic wastewater and beer-brewing wastewater,and observe the morphology and dominant species of microorganism in biofilm with scanning electron microscope（SEM）.The research showed that the system started successfully.The removal rate of COD was stabilized above 70% after 69 days in the course of biofilm culturing.The average removal rate of COD for the treatment of domestic wastewater and beer-brewing wastewater was 61.72% and above 88%,respectively.SEM pictures indicated that the dominant species in biofilm were bacillus and cocci.
