Abstract:
Based on the theory and control principle of sludge bulking, the control strategy framework of sludge bulking was established, and various inducing factors of sludge bulking were comprehensively analyzed by intelligent diagnosis method supported by online and offline data information. According to the structure characteristics of multi-stage A/O process, the causes of sludge bulking are analyzed step by step, and the operation adjustment of the system was implemented in combination with the set response strategy, so as to achieve effective control of sludge bulking and prevent the biochemical system disorder from causing excessive effluent water quality. The expert system has been successfully applied in the sludge bulking control of a municipal wastewater treatment plant in the north of China.
