摘　　要：为了提高水质净化厂对氨氮的处理效果,形成良好的连续降解氨氮的目的,将原有的平流沉淀池尾端1/3区域改造成生物曝气区,填入生物悬浮填料并增加曝气,利用填料上附着的生物膜来降解氨氮,改造后两种工艺对氨氮的处理效果良好。在分批次填入填料的条件下,一个月左右即可达到稳定的去除氨氮效果,去除率达到90%以上。填料上成熟的生物膜生物相丰富,能形成轮虫、独缩虫、钟虫等良好的生态链,进一步保障填料上的生物膜活性,保证良好的氨氮去除效果,为类似的改造工程提供技术参考和借鉴。In order to improve the treatment effect of ammonia nitrogen in water purification plant and form a good continuous degradation of ammonia nitrogen,original horizontal flow sedimentation tank end 1/3 area is transformed into biological aeration area,biological filler is filled and aeration is increased.Biofilm attached on the filler is used to degrade ammonia nitrogen,and the treatment effect of two processes is good after transformation.Under the condition of packing in batches,stable ammonia nitrogen removal effect can be achieved in about one month,and the removal rate can reach more than 90%.Mature biofilm biofacies on the filler were rich,which can form a good ecological chain such as rotifer and vorticella,and further ensure the biofilm activity on the filler and good ammonia nitrogen removal effect,and provide technical reference for similar transformation projects.
