培养因素对好氧污泥颗粒化进程的影响

全面阐述好氧污泥颗粒化的影响因素,指出反应器构造和接种污泥是污泥颗粒化的两个基础性影响因素,污泥沉降时间、曝气量和有机负荷则是培养成败的关健性影响因素,而基质类型、有机负荷、饥饿期、含盐量、温度、pH值、多价阳离子或载体、循环时间、污泥龄、抑制物质只是一般性的影响因素。并对好氧颗粒污泥的研究方向进行了展望。

Factors Affecting Aerobic Sludge Granulation Process

This paper summarizes the factors affecting the progress of granulation and points out that the reactor configuration and seed sludge are basic factors.Settling time,aeration intensity and organic loading rates are of crucial importance to granulation,whereas substrates constituents,periodic starvation,salinity,temperature,pH,carriers and inhibiting substance,operational period,sludge age and polycations execute minor effects.The prospects for the application of aerobic granular sludge were discussed.
