好氧颗粒膜生物污水处理技术研究进展

Research progress of aerobic granular membrane bio-reactor technologies for wastewater treatment

  • 摘要: 随着更为严格的污染物排放标准的出台,开发紧凑、高效和耗能较少的污水处理技术成为水处理领域迫切的需求。综述了近年来国内外好氧颗粒膜生物(AGMBR)法在水处理方面的技术现状,简要介绍了各类AGMBR反应系统的组成和污染物去除性能;系统总结了AGMBR法的膜污染特征,提出AGMBR法相较传统MBR法在缓减膜污染方面具有较大的优势,但也存在不可逆污染问题;分别从底物基质与进料方式、群体感应、胞外聚合物和金属离子4个方面分析了影响好氧颗粒稳定性的原因;并对AGMBR法的应用前景进行了展望。

     

    Abstract: With the introduction of stricter pollutant discharge standards, the development of compact, efficient and less energy-consuming wastewater treatment technologies has become an urgent need in the field of water treatment. The present status of aerobic granular membrane bioreactor (AGMBR) technology in water treatment at home and abroad in recent years was reviewed. The compositions and pollutant removal performances of various AGMBR reaction systems were briefly introduced. The characteristics of membrane fouling of aerobic particles in membrane biofilm were systematically summarized, and AGMBR method was superior to the traditional MBR method in reducing membrane fouling, but it also had the problem of irreversible pollution. The factors affecting the stability of aerobic particles were analyzed from four aspects, i.e. substrate and feeding mode, quorum sensing, extracellular polymer substances and metal ions. The application prospect of AGMBR method was also prospected.
