Intelligent adding control method for PAC solution

Abstract

The invention relates to an intelligent adding control method for a PAC solution, wherein the intelligent adding control method comprises the steps: acquiring the water inlet flow Q1 of a flocculation basin, and presetting the adding amount Q2 of the PAC solution according to a target function; collecting water quality data in the flocculation basin in a preset period, and preprocessing the collected water quality data to obtain preprocessed data; according to the preprocessing data, establishing a multiple linear regression model about the water inlet flow Q1 of the flocculation basin and the addition amount Q2 of the PAC solution, and calculating a partial regression coefficient [theta]1 and a reaction coefficient [theta]2 of the multiple linear regression model to obtain a polynomial regression relational expression; collecting water quality data in the flocculation basin in the next preset period, and calculating the addition amount Q2 of the PAC solution in the next preset period according to the polynomial regression relational expression; and generating a PAC flow change curve to realize addition of the PAC solution. According to the invention, the real-time and precise addition of the PAC solution is realized by constructing the multiple linear regression model.

Description

technical field [0001] The invention relates to the technical field of water supply control, in particular to a PAC solution intelligent dosing control method. Background technique [0002] The safety of water supply for residents is a major issue related to the national economy and the people's livelihood, and the water quality safety of factory water is the most important part of it. Guaranteeing the water quality safety of water supply has been the research focus of various water departments, experts, scholars in the industry, and water supply equipment companies in recent years. Water quality refers to the quality of all water bodies. Except for water molecules, the sum of the types and quantities of all substances in the water body can be used to obtain various characteristics and components of the water body, such as the color and turbidity of the water. In addition to the physical characteristics such as temperature and taste, it also includes the content of inorganic...
