摘要
在总结分析各种污泥膨胀问题理论和假说的基础上,提出了统一的丝状菌膨胀理论。所提出的理论可以很好地解释目前常见的大部分膨胀现象。根据此理论可以很好地指导高、低负荷污泥膨胀的控制和防治。笔者在实验中采用曝气池首端强制曝气的阶段曝气措施,有效控制污泥膨胀,使污泥指数(SVI)从300ml/g降到100ml/g以下.
Based on the analysis and synthesis of various exi sting theory and hypothesis for activated sludge bulking, a unified theory for the phenonmena was proposed. The theory can Satisfactorily explain most of the cammon bulking phenomena, and hence can be utilized in the control and prevention of sludge bulking. Experiment results show that under the quidance of the theory the SVI of slud- ge can be reduced from over 300 ml/g to below 100ml/g.
