Water age detection method based on parallel primary model

Abstract

The invention relates to a water age detection method based on a parallel primary model. The method comprises the steps of acquiring the water temperature and residual chlorine of outlet water of water supply and outlet equipment, and recording the acquisition time; carrying out a three-factor orthogonal experiment according to the collected water temperature, time and residual chlorine and the initial chlorine concentration, determining the attenuation rate of residual chlorine in the water outlet equipment, and the attenuation rate of residual chlorine comprising the rapid consumption rate of residual chlorine and the slow consumption rate of residual chlorine; establishing an Arrhenius relation model of the residual chlorine attenuation rate and the water temperature; establishing the parallel primary model according to the Arrhenius relation model to simulate the change conditions of residual chlorine and water age in the water body; and processing the parallel primary model by utilizing linear regression estimation, and approximately estimating the water age of the water outlet equipment under the condition that the current residual chlorine, the initial residual chlorine and the water temperature are known. According to the invention, intelligent and precise detection of the water age of drinking water in an urban water supply system can be realized.

Description

technical field [0001] The invention relates to the technical field of water age detection, in particular to a water age detection method based on a parallel first-level model. Background technique [0002] Water is not only the lifeblood of the entire national economy but also one of the basic materials for human survival and development. Water supply is one of the key issues related to the sustainable development of our country. With the acceleration of my country's urbanization and the rapid development of the national economy, my country's urban water supply has entered a period of rapid development. In order to meet the basic needs of industrial production and residents' lives, the water supply industry has shifted from ensuring sufficient water supply to improving water supply safety and upgrading. The direction of water quality and modern management. Various water storage equipment (such as water tanks, water tanks, etc.) in the urban water supply system are indispen...

AI Technical Summary

Problems solved by technology

[0003] There are many conventional methods for water age calculation, such as a large number of experiments to predict the renewal time of water tanks in each community to calculate water age, etc. However, this kind of experiment is greatly affected by external interference, and the resulting results have large errors and are not representative.
