Research on the Relationships between Filamentous Organisms and Flocculate Structure in Activated Sludge

LONG Teng rui, HE Qiang, LIN Gang (Faculty of Urban Construction, Chongqing Jianzhu Univ., Chongqing 400045, China)  
The relationships between filamentous organisms and flocculate structure in the activated sludge were studied in this paper. It was found that the structure of activated sludge could be divided into six types. The proportion of each type and the action of filamentous organisms on the formation of sludge structure would be different under different treatment processes and operating condition. Sludge bulking could be divided into structure filamentous organisms bulking and non-structure filamentous organisms bulking, different measure should be taken in order to control the bulking.
