英文摘要

      Sludge bulking is a common abnormal process in activated sludge wastewater treatment and has serious harm. It is of great significance to study the identification and suppression methods of sludge bulking for the normal operation of municipal wastewater treatment. In this paper, the identification and suppression methods of sludge bulking in the process of municipal wastewater treatment are summarized. Firstly, the urban wastewater treatment process is summarized, and the concept, main characteristics, types and causes of sludge bulking are introduced. Secondly, the sludge bulking identification methods based on the microbial physiological characteristics, mechanism model, image recognition and data driven are summarized. The development status of sludge bulking identification methods are analyzed and their advantages and disadvantages are pointed out. Then, the sludge bulking suppression methods based on the process regulation and mechanism characteristics are summarized. The development status of sludge bulking suppression methods are analyzed and their advantages and disadvantages are compared. Finally, the full text is summaried, and the main problems in the identification and suppression of sludge bulking are pointed out and the research trend is prospected.
