摘　　要：目前,污水的好氧生物处理产生大量剩余污泥,常规的污泥处理和处置需要花费大量的人力和物力,处置不当极易对环境造成二次污染。利用微生物方法进行污泥减量清洁无污染,是一项实现污泥源头治理的绿色技术。根据生物处理工艺中影响剩余污泥产生的可能途径,将污泥减量技术分为降低细菌合成量的解偶联技术、增强微生物利用二次基质进行隐生长的溶胞技术、利用食物链作用强化微型动物对细菌捕食技术,介绍了各种技术的最新研究进展;并围绕生物法污泥减量技术这一课题,提出了今后的研究方向。Excess activated sludge produced in the biological treatment process of wastewater required costly disposal and induced serious environmental pollution if the treatment was not suitable. Sludge reduction by microbe was clean and not contaminative, so it was green technology achieving source control of sludge. According to production principle of excess activated sludge in biological treatment process. The possible approaches for sludge reduction might classify three aspects： uncoupling metabolism reducing cell synthesize , cryptic growth improved through cell lysis and enhanced microfauna prey using food chain . The updated progress in the research of microbial sludge reduction was introduced, and finally, the direction in the research of sludge reduction was presented.
