An expert system for energy-saving control of precise aeration and process optimization

System Introduction In order to solve the problem of high energy consumption and unstable process, our company introduced foreign advanced sewage treatment energy-saving control model, process optimization control model, combined with many years process design, commissioning,
Operation and other experience, developed a set of energy-saving control expert system for Carrousel oxidation ditch process . with economical and reliable hardware, network architecture and other solutions to achieve the process self-learning and optimization operation, while greatly reducing energy consumption. the effectiveness of the control target guarantee model on the stable control of dissolved oxygen concentration

The system is stable,
the dissolved oxygen in the aeration pool is controlled accurately, the dissolved oxygen concentration is controlled in the lowest energy consumption
parameter, and the software and hardware conditions are provided for the optimization
and stability control of the process-related parameters. Hierarchical implementation of control strategy and intelligent switching , which is helpful to ensure the safe operation of the system. Control method model calculation and control, fuzzy level control,

Dynamic energy-saving control, static energy-saving control, fuzzy level control, number combination control, rotational speed control, energy balance control.
Minimum energy consumption parameters: the minimum energy consumption to control the sewage treatment process, in the process of stable operation, effluent standards in the case of a variety of parameters is called the lowest consumption parameters. The minimum energy consumption parameter is not the critical point for the process to operate stably. Energy Saving effect

1, to maintain aeration pool each section of aeration can meet the current aeration pool in each part of the biochemical reaction required by the amount of air, is conducive to microbial population growth and reproduction, so as to ensure the stable operation of biochemical unit process.
2, to adapt to the sewage plant water quality and water changes to maintain the aeration pool dissolved oxygen concentration stability.
3, through the determination of dissolved oxygen analyzer and model data for the adjustment of the speed of the aeration machine, so that even in the sewage plant water quality and water changes in the situation, the concentration of dissolved oxygen in the aeration pool can remain stable, the determination of deviation stability in the set value ±0.3mg/l.
4, timely correction of sludge reflux ratio, so that the sludge concentration to maintain a stable state.
5, reduce the aeration unit and sludge reflux Unit energy consumption, energy saving in 15%~40%. system composition
