This invention discloses a wastewater treatment safety management method and system based on nano-microbubble technology, belonging to the field of safety management technology. It involves real-time acquisition of water quality signals from the target wastewater treatment unit, calculation of the water quality signal disturbance entropy, and projection of this entropy onto a preset bubble disturbance trajectory library. The degree of agreement between the current water quality fluctuation and the trajectory library is then calculated. Based on the comparison of the agreement with a preset threshold, the water quality fluctuation state is divided into abnormal and unknown states. In the unknown state, the normality of the state is calculated to further determine whether the current water quality fluctuation is abnormal and whether to trigger a safety management alarm. Thus, when nano-microbubbles cause fluctuations, the existence of process risks can be determined based on the actual situation, avoiding frequent false alarms and misoperations, thereby reducing energy waste and process disturbances. Simultaneously, this method avoids masking true water quality anomalies, promptly identifies potential safety hazards, and ensures the safety and stability of the wastewater treatment process.
