摘　　要：A^(2)O-BAF双污泥系统集A^(2)O和BAF各自优势于一体,通过A^(2)/O活性污泥系统和BAF生物膜系统串联组成,短污泥龄运行的A^(2)O主要完成除磷和反硝化,长污泥龄的BAF实现稳定的硝化过程。该工艺解决了传统A^(2)O中存在的固有污泥龄矛盾和碳源竞争问题,作为一种新型高效组合工艺,近年来受到广泛关注。以该组工艺为基础,通过合理控制运行参数、研究低温条件和低温菌植入对系统影响,对提高系统的脱氮除磷效率及最大限度发挥A^(2)O-BAF双污泥系统自身的优势具有重大现实意义。The A^(2)O-BAF dual sludge system integrates the respective advantages of A^(2)O and BAF.It is composed of the A^(2)Oactivated sludge system and the BAF biofilm system in series.The A^(2)O operating with short sludge age mainly completes phosphorus removal and denitrification,and the BAF with long sludge age realizes a stable nitrification process.This process has solved the inherent sludge age contradiction and carbon source competition problems existing in traditional A^(2)O.As a new and efficient combination process,it has attracted wide attention in recent years.Based on the combined process,it is of great practical significance to improve the nitrogen and phosphorus removal efficiency and maximize the advantages of the A^(2)O-BAF dual sludge system by reasonably controlling operating parameters,studying the effects of low-temperature conditions and low-temperature bacteria implantation on the system.
