摘要:
在过去的20多年里,好氧颗粒污泥(AeGS)技术在污水生物处理领域得到广泛研究和实际应用。目前,国内外已在AeGS形成机制、工艺参数优化、功能菌群解析、微生物代谢分泌强化等方面取得了研究进展,尤其在揭示颗粒化机理和加速颗粒化过程上成果显著,基于AeGS形成过程的四步理论和三大假说,已能实现AeGS在30 d甚至更短期内的快速培养。但是,实际生产运行中颗粒易失稳的问题始终未得到解决,成为AeGS工艺工程应用长期稳定运行的主要技术瓶颈。本文围绕AeGS生产运行过程中结构失稳及其影响因素进行了文献考察,从传质阻力、优势微生物结构和功能、EPS分泌与组成、颗粒内聚力等方面开展分析与讨论,总结了强化颗粒结构稳定的主控因子,包括颗粒粒径控制、功能菌群结构优化(通过慢速生长微生物富集、丝状菌及内核厌氧菌抑制)、EPS分泌特性调控、群体感应调控和颗粒内核外源强化(通过添加金属离子、成核剂,接种颗粒污泥或EPS),以期为AeGS工艺实际生产应用的长期稳定运行提供多方面的调控策略。未来将结合表位表征技术、先进的分子生物学工具以及新型生物化学和生物物理学方法,深入挖掘颗粒失稳诱因和机理,从而为维持AeGS长期结构稳定性指明方向。图3表1参154
Abstract:
Over the past two decades, aerobic granular sludge (AeGS) technology has been widely studied and practiced in biological wastewater treatment. Up to now, lots of studies have been carried out worldwide in view of AeGS formation mechanism, parameter optimization, functional microbial analysis and secretion enhancement of extracellular polymeric substances (EPS), remarkable achievements have been made in revealing the mechanism of granulation and accelerating the granulation process particularly. Based on the four-step theory and three hypotheses of AeGS formation process, AeGS can be rapidly cultivated in 30 days or even shorter time. However, the instability of AeGS during long-term operation has not been effectively solved, which greatly impedes the engineering application of AeGS. This review focuses on AeGS instability and its related factors. The key influence factors for structure stability of AeGS are summarized from the aspects of mass transfer resistance, structure and functions of dominant microorganisms, EPS secretion and composition and cohesion of granules. The corresponding strategies include particle size control, optimization of functional microbial community structure (through enrichment of slow growing microbes, inhibition of filamentous bacteria and anaerobic bacteria in the core), regulation of EPS characteristics and quorum sensing, and enhancement of particle core intensity (by adding metal ions and nucleating agents, inoculating granular sludge or EPS), so as to provide possible solutions for the stability of AeGS during long-term operation. In situ techniques, advanced molecular biology tools, new biochemical and biophysical approaches are supposed to function cooperatively in future researches to further explore the causes and mechanisms of granular instability, providing guidance for the maintainance of AeGS structural stability in the long term.
