摘　　要：采用竹丝填料生物反应器处理某大学实验室废液处理系统尾水。实验结果表明,竹丝填料生物反应器对废液处理系统尾水中COD、TN和NH4^＋-N去除率分别为84.00%-88.00%、15.47%-28.00%和37.96%-56.55%,其出水COD和NH4^＋-N的含量远低于GB 18918-2002的一级A标准。通过扫描电子显微镜和体式显微镜的观察发现,竹丝填料表面容易被分解和形成较多的微小孔洞,并形成复杂的生物膜系统和提供碳源以及孔洞对生物膜的保护可能是该生物反应器良好效果保证的主要原因。Effluent of lab wastewater treatment system was treated by a bioreactor containing filamentous bamboo （BCFB）. The experimental results showed that the COD, TN and NH4^＋-N removal rates were 84.00%-88.00%, 15.47%-28% and 37.96%-56.55% respectively by using BCFB, and the concent of the effluent COD and NH4^＋-N was much lower than that of first grade （A） GB 18918-2002. Some tiny holes on the surface of filamentous bamboo padding formed by decomposition were readily observed by a scanning electron microscope and a stereomicroscope, and the complex biofilm system and carbon source supplied as well as the biofilm in the micro-holes were key causes of effective treatment for effluent of lab wastewater treatment system by using BCFB.
