Intelligent sewage treatment control system

Abstract

The invention discloses an intelligent sewage treatment control system. The intelligent sewage treatment control system comprises a sewage automatic collection module, a sewage control and adjustmentmodule, a sewage prediction and analysis module, and a production visualization module; the sewage automatic collection module is used for collecting operation data and status information of the equipment and instruments, and control the operation of the equipment; the sewage control and adjustment module is used for precise aeration; the sewage prediction and analysis module is used for predicting a dissolved oxygen value and feeding back to the control and adjustment module; and the production visualization module uses a mixed programming, modular and loadable way to call and run each other,and intuitively displays various parameters, alarms, models and other information in the sewage treatment process. By comparing with an actual sewage plant test, the aeration tank water inlet index and the dissolved oxygen value at the time in the case of better effluent are obtained as samples; a support vector machine model optimized by a particle swarm optimization is trained according to thesamples; and the accurate prediction of dissolved oxygen under different water inlet conditions is realized finally; and then the oxygen supply amount can be quickly adjusted according to the predicted result to achieve precise aeration through the mixed programming method, thereby optimizing the effluent water quality.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an intelligent sewage treatment control system. Background technique [0002] Sewage treatment has been in an unstable state, and the quality of influent and effluent is constantly changing, resulting in constant changes in other parameters and effluent quality. The purification mechanism is mainly that the microorganisms attached to the sludge in the aeration tank are under appropriate oxygen conditions. , decompose pollutants through metabolism, and realize the purification of sewage. Therefore, the control of dissolved oxygen is the most critical. [0003] Among them, excessive aeration not only causes waste of electric energy and increases operating costs, but also the dissolved oxygen is brought to the anoxic zone through the internal reflux to affect the effect of denitrification, and the dissolved oxygen is brought to the anaerobic zone through the external reflu...

Problems solved by technology

[0005] At present, dissolved oxygen cannot be accurately predicted and controlled online in the domestic sewage treatment process, and the precision and accuracy of the prediction model need to be improved; Accurate aeration in the sewage treatment process remains in the experimental stage, and the actual application effect needs to be improved; however, in the domestic sewage treatment process, sewage control manufacturers, artificial intelligence manufacturers, and mathematical model manufacturers have not formed a complete set of intelligent sewage control methods; The sewage treatment control system can realize real-time monitoring of various parameters of the equipment, and through intelligent algorithms, according to different sewage water quality, adjust the treatment strategy and adjust the parameter settings in key steps
