AI Technical Summary

Technical Problem

Traditional wastewater treatment dosing methods cannot predict water quality changes in advance, resulting in delayed response and slow adjustment. Furthermore, existing intelligent dosing technologies have low accuracy and reliability in predicting under complex operating conditions, making it difficult to achieve stable and precise dosing of chemicals, which can easily lead to waste of chemicals, sludge bulking, or effluent exceeding standards.

Method used

The intelligent chemical dosing system for wastewater treatment based on the smart water management platform generates two independent dosing strategies through multi-source data collection, time-series evolution trajectory curves, and AI dosing prediction models. These strategies are then compared, analyzed, and integrated to generate precise chemical dosing instructions. By combining operating mode tags and global inflection point change directions, dynamic dosing is achieved.

Benefits of technology

It enables proactive perception of the changing trends of influent water quality indicators, improves decision robustness and prediction accuracy under complex operating conditions, avoids waste of chemicals and excessive effluent, reduces operating chemical consumption, and enhances the sewage treatment system's resistance to shock loads.
