摘要
针对生物膜法在水环境治理中存在的不足,以生态碳纤维、醛化纤维(软性填料、组合填料)等材料为例,选取挂膜启动时间、挂膜量、氮磷去除效果等指标,比较不同材料的污水处理性能。结果表明,碳纤维的挂膜启动时间及挂膜量均优于其他两种材料,其对氨氮和总磷的去除率分别为73.8%、56.4%,组合填料与软性填料对氨氮的去除效果基本相同,对总磷的去除效果为组合填料高于软性填料,去除率分别为45.7%、41.8%。
Aiming at the shortcomings of biological membrane method for improving water conservancy environment, ecological carbon fiber and aldehyde fiber （soft filler, composite filler） were selected as the research objects for comparative study on sewage treatment performance of different materials. The results were compared from the three indexes of starting time, the amount of biofilm and the removal effect of nitrogen and phosphorus. The study indicates that the start-up time and biofilm amount of carbon fiber are better than the other two materials, and the removal rates of ammonia nitrogen and total phosphorus are 73.8 %, 56.4 % respectively. The composite filler and the soft filler have the same removal effect on the ammonia nitrogen, but the removal effect of the total phosphorus is that the composite filler is higher than the soft filler, which are 45.7% and 41.8%, respectively.
