| 摘 要： | 采用氧化和接枝蛋白分子的方法对聚苯乙烯滤料进行表面改性处理,并将其用于曝气生物滤池(BAF)中以检验其对BAF处理性能的改善效果.结果表明:改性处理后的滤料无论是在挂膜速度上还是在生物量上都明显优于未改性滤料,其表面生物量约为未改性滤料的3倍;当COD容积负荷和氨氮负荷分别小于4、0.4 kg/(m3·d)时,采用改性聚苯乙烯滤料的BAF可有效去除COD和氨氮,去除率分别高达86.1%和57%.

| Abstract: | Oxidation and grafting protein method was used to modify polystyrene medium surface, and the modified polystyrene media were used in biological aerated filter (BAF) in order to test the per-formance improvement of BAF. The results show that the biofilm formation velocity and biomass on the modified media are increased evidently, and the biomass is about 3 times more than that on unmodified monia nitrogen effectively, with the removal rates of 86.1% and 57%. |
