Water plant real-time dosing amount prediction method and device based on decision tree algorithm, and medium

Abstract

The invention discloses a water plant real-time dosing amount prediction method and device based on a decision tree algorithm and a medium. The method comprises the steps of obtaining historical dosing data of a water plant; preprocessing the historical dosing data to obtain training data and test data; inputting the training data into a water plant real-time dosing amount prediction model, and training the prediction model to obtain a trained dosing amount prediction model; inputting test data into the trained dosing amount prediction model, and verifying the prediction precision of the dosing amount prediction model; and acquiring real-time raw water data, inputting the real-time raw water data into the trained dosage prediction model, setting target effluent turbidity, and outputting predicted values of the dosage of the flocculating agent and the dosage of the coagulant aid by the dosage prediction model. According to the method, the historical dosing data is predicted and analyzed in real time based on the decision tree algorithm to accurately predict the real-time dosing amount, so that the dosing amount is scientifically configured and the water treatment cost of a water plant is reduced on the premise of ensuring the stable effluent quality.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a method, device and medium for predicting real-time dosage of water in a water plant based on a decision tree algorithm. Background technique [0002] Water supply system is an important aspect of modern city construction. In the standard of drinking water quality, turbidity is an important index, which is directly related to the quality of water. Dosing flocculation and sedimentation is an important process in the water treatment process of the waterworks, and its effect will directly affect the subsequent process and the quality of the factory water. Coagulation is a key technology in the process of waterworks, which directly affects the quality of water produced by the waterworks, and the important factor affecting the coagulation effect is the dosage of coagulant. [0003] The energy consumption and chemical consumption in the operation of the water plant have a gre...

AI Technical Summary

Problems solved by technology

[0003] The energy consumption and chemical consumption in the operation of the water plant have a great impact on the cost of water treatment. In the case of traditional processes, the dosage is often set artificially based on the experience of the operation managers, which leads to large fluctuations in the turbidity of the effluent; or the dosage Excessively large, resulting in an increase in the cost of water treatment
