摘　　要：污水好氧处理会产生大量污泥,剩余污泥的处理成本高昂,减少污泥产量势在必行。文章介绍了代谢解偶联、增加维持能量消耗、隐性生长、微型动物捕食、高溶解氧工艺和膜生物反应器等污泥减量技术,比较了各种技术的优缺点,指出了不同技术结合将成为污泥减量技术的发展方向。Great amount of sludge is produced during aerobic biologically wastewater treatment. Excess sludge treatment process is expensive, thus, reducing excess sludge production becomes extremely impetus. Such recently developed methods for sludge reduction as uncoupling metabolism, increasing maintenance energy requirement, cryptic growth, microfauna prey, high dissolved oxygen process, membrane bioreactor(MBR) etc were reviewed with comparison of the advantages and disadvantages of each technology.It is concluded that the combination of different technology will become the mainstream.
