悬浮填料同时生物脱氮除磷研究进展

Research Progress of Simultaneous Biological Nitrogen and Phosphorus Removal by Suspension Packing

悬浮填料由于具有较大比表面积和吸附性,易于在其表面形成生物膜,有利于微生物生长繁殖,具有同时脱氮除磷性能,成为目前研究热点。本文阐述了悬浮填料表面生物膜脱氮除磷机理,不同条件对悬浮填料脱氮除磷效果的影响,以及当前悬浮填料应用于脱氮除磷的研究进展,和对悬浮填料同时生物脱氮除磷工艺的展望。

As the result of the large specific surface area and adsoption it is easy for suspension packing to form a biofihn which is conducive to the growth and reproduction of microbials on the surface. The suspension packing with the performance of simultaneous nitrogen and phosphorus removal become a hot topic. This paper expounds that the mechanism of nitrogen and phosphorus removal on the surface of suspension packing, the effect on nitrogen and phosphorus removal performance of suspension packing by different conditions, the research progress of suspension packing applied to nitrogen and phosphorus removal, and the expectation of the process of simultaneous nitrogen and phosphorus removal by suspension packing.
