摘要
介绍了好氧颗粒污泥的特性,包括外观结构、SVI、表面疏水性等,重点分析了影响好氧颗粒污泥形成及维持稳定运行的关键因素,如沉降时间、水力剪切力、有机负荷、Ca2+浓度等,并阐述了好氧颗粒污泥的国内外研究进展,同时对好氧颗粒污泥的研究方向和应用前景进行了展望。
The physicochemical and biological characteristics of aerobic granular sludge, such as morphol- ogy and structure, sludge volume index, hydrophobic surface of the sludge and so on, were introduced. The key factors of settling time, hydraulic shearing, organic loading and Ca2 ＋ concentration on the aerobic granular sludge formation and maintaining the stable operation were analysed. The domestic and abroad research progress of aerobic granular sludge was summerized. The research direction and the prospect in application of aerobic granular sludge were expected.
