A Unified Hypothesis for Filamentous Bulking in Activated Sludge Processes
统一的活性污泥丝状菌型膨胀理论

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.
