On-line monitored secondary water purifying ozone system and process

Abstract

The on-line monitored secondary water purifying ozone system has an oxygen maker, an ozone generator with inlet connected to the outlet of the oxygen maker, an ozone-water mixing pump with inlet connected to the outlet of the ozone generator, an oxidizing tank with water inlet connected with the water outlet of the ozone-water mixing pump, an ozone tail gas decomposer with gas inlet connected to the gas exhaust port of the oxidizing tank, and a filter connected to the water outlet of the oxidizing tank and with clean water flowing out from the water outlet. The present invention can monitor ozone content in water, and regulate ozone production and ozone concentration in water automatically to ensure the quality of the secondary supplied water.

Description

technical field [0001] The invention relates to an ozone purification system capable of performing ozone disinfection on drinking tap water and a purification method used in the system. Background technique [0002] Due to the old water pipe network and the long distance of the pipe network in the city, only using the pipe network for water supply cannot guarantee the quality of drinking water for urban residents, and it is necessary to carry out secondary purification of the pipe network water supply. In the prior art, the secondary purification method for the water supply of the pipe network is simple, lacks continuity, and the reliability of the equipment is poor. Especially for the characteristics of the continuous change of the water volume of the secondary water supply, there is currently no one that can achieve continuous and reliable disinfection, and can Online monitoring of the disinfectant concentration, timely closed-loop control of the dosage of disinfectant as ...

AI Technical Summary

Problems solved by technology

[0003] The method of ozone disinfection is to add ozone in water. Although this method is relatively safe, the relevant equipment for disinfection using ozone is simple and the control function is not complete. For example, the amount of ozone added cannot be automatically adjusted. When the water supply or water quality changes When a single fixed amount of ozone is added, the concentration of water-soluble ozone is unstable, which directly affects the effect of ozone disinfection and sterilization; automatic and continuous monitoring of the concentration of water-soluble ozone cannot be achieved, and what concentration should be used for disinfection to achieve the effect for different water qualities, even if there is Concentration monitoring does not have the function of controlling signal output, feedback control of the ozone generator equipment, and timely adjustment of the amount of ozone generated, but requires manual intervention, which will cause the water quality after the secondary purification to remain unstable and fail to achieve the secondary purification. Purpose

Therefore, the existing ozone disinfection methods cannot meet the high standards that people require for water quality.
