摘要
综述了好氧颗粒污泥颗粒化研究进展及好氧颗粒污泥处理技术在废水生物处理中的应用.着重讨论了好氧颗粒污泥的形成机理,分析了好氧颗粒污泥培养过程中的影响因素,以及好氧颗粒污泥技术在废水生物处理和工程应用中的研究进展.好氧颗粒污泥的形成、发展和成熟过程可分为5个不同阶段,污泥颗粒化过程取决于基质组成与负荷、适当的水力选择压和工艺操作参数等因素.
The development and applications of aerobic sludge granulation technology in wastewater biological treatment are reviewed. The aspects discussed include the formation process and formation mechanism of aerobic granular sludge, major factors affecting granulation, and their applications in wastewater biological treatment and engineering application. During the formation, development and maturation of aerobic granular sludge, there exist five noticeable stages. Granulation depends on various factors like the stomatic composition and load, appropriate hydraulic selection pressure and technological operating parameters, etc.
