为了研究不同填料滤池对生活污水的净化效果和特性,构建了平行的竹丝填料曝气生物滤池和陶粒/竹丝复合填料曝气生物滤池,通过连续流对比实验研究2个滤池对污染物的去除效果.结果表明,陶粒/竹丝填料曝气池净化效果更好,在污水氨氮浓度变化时,抗冲击负荷能力更强,并能增强反硝化性能,有效去除污水中的氮盐和磷盐.相比于竹丝填料滤池而言,陶粒/竹丝填料滤池对氨氮、总氮、总磷的平均去除率高出10.9％、10.0％和15.4％.“,”To investigate the purification efficiency and performance of biological filters with difference fillers,two parallel biological filters were established involoved biological aerated filter with filamentous bamboo and biological aerated filter with filamentous bamboo as well as palygorskite ceramistite,purification efficacy of two biological filters were studied under a continuous-flow condition.The experiment results indicated that biological aerated filter with filamentous bamboo as well as palygorskite ceramistite obtained higher removal rate for nutriuent compared to biological aerated filter with filamentous bamboo,and stronger shock load ability as well as denitrification performance.Compared with biological aerated filter with filamentous bamboo,the biological aerated filter with filamentous bamboo as well as palygorskite ceramistite has more 10.9％,10.0％ and 15.4％ for ammounia nitrogen,total nitrogen and total phosphorus.
