摘要:

好氧颗粒污泥(aerobic granular sludge,AGS)具有较高的生物丰度、良好的沉降性能、高效的脱氮除磷及抗冲击负荷等优点,在废水处理领域得到广泛关注。但成粒速度慢,成粒后易解体是限制AGS广泛应用的技术瓶颈。因此,实现AGS快速颗粒化并维持稳定结构是AGS技术推广应用的关键。首先通过成粒模型假说总结了AGS典型的结构,分析了优势菌群及其空间分布特性,之后从宏观和微观2个尺度论述了关于AGS结构稳定性影响因素方面的研究进展,并指出了AGS技术今后的研究重点。

Abstract:

Aerobic granular sludge(AGS) has the advantages of high biodiversity richness, good settling property, high efficiencies of nitrogen and phosphorus removal, and better resistance to shock loads, which has attracted a wide spread attention in the field of wastewater treatment. However, it still faces great challenges in widespread application due to the bottleneck of slow speed and time-consuming in granulation process and easy particle disintegration after granulation. Therefore, rapid granulation and keeping particle structure stability is the key to the extension and practical application of AGS technology. The typical morphological structures of AGS were summarized firstly with the granulation model hypotheses, and then the dominant microflora and its spatial distribution feature were analyzed. The research progress of the influencing factors on particle structure stability were mainly discussed thereafter from the macroand micro-scale. Finally, the future research emphasis of AGS technology was proposed.

Key words: aerobic granular sludge(AGS), granular structure, zoogloea, filamentous bacteria, structure stability
