摘　　要：填料性能对曝气生物滤池的处理效能、基建投资和运行费用等有着重要的影响 ,为了考察国产球形生物陶粒在污水深度处理中的应用效果 ,探讨其工程应用前景 ,对国产球形生物陶粒和进口专利填料BIOLITES在曝气生物滤池(BAF)处理城市污水厂二级出水的应用效果及反应器运行特征进行了对比研究。试验结果表明 ,国产球形生物陶粒与进口专利BIOLITES填料BAF对城市污水厂二级出水中COD、浊度和NH3 -N的去除效能基本相同 ,平均去除率与水力停留时间呈正相关关系 ,当水力停留时间为 2h时 ,两种填料BAF处理水水质均满足生活杂用水水质标准。国产球形生物陶粒BAF在运行周期和反冲洗等方面比进口专利BIO LITES填料稍具优势。The COD and NH_3-N removal effects for secondary effluent were approximately equivalent between domestic spherical bio-ceramic and imported patent media BIOLITES in this test. The removal effect and retention time were positively relative. When retention time was 2 hours, the effluent could reach the secondary treatment standard, COD≤30 mg·L-1 and NH_3-N≈1 mg·L-1. In operation, domestic spherical bio-ceramic took quite advantage over BIOLITES in longer running cycle and easier flushing. The result showed that domestic spherical bio-ceramic could replace imported patent media BIOLITES in secondary wastewater treatment.
