AI Technical Summary

Technical Problem

The existing single-star sedimentation tank control system cannot simultaneously optimize sedimentation efficiency and energy consumption. The sedimentation boundary flow velocity is not dynamically coupled with the real-time sludge interface, and energy consumption control is independent of the equipment health status, resulting in high operating energy consumption and a high risk of equipment failure.

Method used

The energy-saving single-star sedimentation tank control system adopts adaptive flow velocity control. It acquires tank operation and environmental perception data through the data acquisition module, generates basic flow velocity and energy consumption control schemes through the scheme generation module, performs scheme verification and optimization through the scheme verification module, performs feedback compensation through the adaptive compensation module, and realizes coordinated control of the inlet valve group, sludge discharge mechanism and variable frequency drive system through the collaborative control module.

Benefits of technology

It achieves Pareto optimality between sedimentation efficiency and energy consumption, reduces the risk of equipment failure, reduces energy consumption, improves adaptability to water quality fluctuations and management of equipment health status, and avoids energy waste and excessive effluent.
