Water treatment methods based on ozone disinfection/ultraviolet disinfection/chlorine disinfection

Abstract

The invention relates to a water treatment method based on ozone disinfection / ultraviolet disinfection / chlorine disinfection. The reclaimed water can be disinfected by ozone disinfection ultraviolet disinfection and chlorine disinfection in turn. According to the ozone, ultraviolet ray and chlorine-containing preparation dosage determination model provided by the invention, the application amountof ozone, ultraviolet ray and chlorine-containing preparation can be determined more accurately according to the standards or requirements to be satisfied. The invention solves the problems that the single disinfection technology only inactivates limited pathogenic microorganism species, a large number of toxic and harmful disinfection by-products are generated, and the disinfectant quantity is difficult to determine in actual operation. The invention can effectively remove the chroma and smell of the reclaimed water, improve the disinfection technical efficiency, control the quantity of the microorganisms in the effluent, reduce the operation cost of the disinfection process, and ensure the safety of the reclaimed water.

Description

technical field [0001] The invention belongs to the technical field of water treatment and disinfection, and in particular relates to an ozone / ultraviolet / chlorine detoxification method for regenerated water and a method for determining a disinfection dose. Background technique [0002] Water is an important resource for our human survival, but most of the water bodies in nature need to be treated and disinfected before they can be used in people's lives, so the technology of water treatment and disinfection has been born. The early liquid chlorine-based disinfection method caused widespread concern because it was prone to produce disinfection by-products, which led to research on other water treatment disinfection processes in the industry. At present, the disinfection technologies that exist in the industry include several common disinfection processes such as chlorine dioxide disinfection, ozone disinfection, ultraviolet disinfection, and sodium hypochlorite disinfection....

AI Technical Summary

Problems solved by technology

In addition, the present invention also solves the problems of the limited types of inactivated pathogenic microorganisms, the generation of a large number of toxic and harmful disinfection by-products, and the difficulty in determining the disinfection dose in actual operation in the previous single disinfection treatment technology.
