摘　　要：好氧消化是常用的污泥处理技术之一。受污泥颗粒细胞水解慢的限制,污泥好氧消化时间较长。破解预处理是缩短污泥好氧消化时间的有效途径。综述了污泥好氧消化的几种预处理方法,包括超声波法、电化学法、臭氧氧化以及碱解和超声波联用的方法,并提出污泥好氧消化预处理的发展方向。The aerobic digestion was one of the common methods for sludge treatment,Sludge aerobic digestion needs long time because the hydrolysis of microbial cells was slow.Disintegration pretreatment of sludge was an effective approach to cut down the aerobic digestion time.Several pretreatment methods of sludge aerobic digestion were introduced,such as ultrasonics,electrochemical oxidation,ozone oxidation and the combination of alkaline and ultrasonics.The research direction in the future was pointed out in this paper.
