Description

technical field [0001] The invention relates to the field of water plant purification technology, and more specifically relates to a coagulation dosing control method and system based on an artificial neural network algorithm. Background technique [0002] The purification process of the waterworks mainly includes two parts: dosing and dispensing, and coagulation dosing is the most important treatment process in the purification process. It makes various suspended particles, impurities and pathogenic microorganisms in the water coalesce and bond, In order to meet the water quality requirements of residents in the factory. [0003] Coagulation dosing is the core process in the water treatment process of the waterworks, and its coagulation and sedimentation effect directly affects the quality of the factory water. Coagulation dosing is a complex physical and chemical reaction process, which has the characteristics of nonlinearity, multiple input factors (source water flow, so...

AI Technical Summary

Problems solved by technology

Coagulation dosing is a complex physical and chemical reaction process, which has the characteristics of nonlinearity, multiple input factors (source water flow, source water turbidity, temperature, pH value, drug concentration, etc.), uncertainty, time-varying, ambiguity, etc. , it is difficult to accurately establish a mathematical model of the reaction process, and there is no effective control method in China to solve the problem of precise dosing, so it is necessary to research and develop a set of coagulation dosing control system with self-adaptive and self-learning capabilities, Accelerating the Process of Automation in my country's Waterworks
