摘　　要：作为研究不规则物体与非线性系统的一种有效工具,分形理论在厌氧氨氧化(anaerobic ammo-nium oxidation,ANAMMOX)颗粒污泥床反应器性能研究中具有广阔的应用前景。采用分形理论,可以描述ANAMMOX颗粒污泥的粒径、密度、渗透性等特征,从而预测其沉降性能。在ANAMMOX颗粒污泥床中,孔隙是传质的主要通道,以分形维数描述ANAMMOX颗粒污泥床的孔隙分布特征,建立孔隙结构与水分运动的关联方程,对于ANAMMOX颗粒污泥床反应器的过程控制和操作优化具有重要的理论指导意义。As an effective tool in exploring irregular objects and nonlinear systems, fractal theory demonstrates wide prospects in the researches of ANAMMOX granule sludge blanket bioreactor. The particle size, density and permeability of ANAMMOX granule sludge can be described by fractal theory,thus predicting its settling performance. Pores are main passages of mass transfer in ANAMMOX granule sludge blanket. The establishment of water moving equations based on the fractal theory that depicted the characteristics and distribution of pores in ANAMMOX granule sludge is of great significance in guiding process control and optimization of operation of ANAMMOX granule sludge blanket bioreactor.
