RESEARCH PROGRESS ON INSTABILITY MECHANISMS AND IMPROVEMENT STRATEGIES OF AEROBIC GRANULAR SLUDGE

  • 摘要: 好氧颗粒污泥(AGS)技术是当前具有良好发展潜力的废水生物处理强化技术之一。然而,AGS的快速培养及其在连续工艺中的长期运行稳定性仍是该技术应用所面临的主要挑战。通过文献分析,从物理、化学和微生物等方面分析了AGS失稳的主要原因和潜在机理,论述了颗粒污泥稳定性的主要增强策略,即选择性污泥排放、优化颗粒粒径、强化EPS分泌、控制菌群生长速率、抑制丝状菌的过度增殖、外源强化以及外加信号分子。鉴于AGS失稳机理的复杂性和单一改善策略的局限性,AGS结构的长期稳定维持需要采用多种策略进行综合管理,且未来对于AGS适居带(goldilocks zone)的研究应更加注重从物理、化学和微生物学等角度进行系统考虑。
