Method and system for sterilizing drinking water via plasma ozone chlorination

Abstract

The invention discloses a method and a system for sterilizing drinking water via plasma ozone chlorination. The method comprises the following steps: adding chemicals for flocculation; performing high-class oxidation pretreatment; performing flocculation treatment; filtering; performing high-class oxidation treatment; performing activated carbon adsorption; performing chlorination treatment. According to the technical scheme of the invention, high-precision combination of integral water treatment equipment is achieved, integral integration and automatic control of a whole system are achieved, the high efficiency and the sterilization and disinfection functions of oxidation of high-class plasma oxidized gases upon macromolecules in water can be sufficiently brought into full play, and a safe, reliable, thorough and residue-free sterilization process is provided to sterilize drinking water.

Description

Technical field [0001] The present invention relates to the field of ozone application, in particular to a method and system for disinfecting drinking water by plasma ozone chlorination. Background technique [0002] With the continuous improvement of people's living standards and the continuous enhancement of environmental awareness, the quality of drinking water and the standards for sewage treatment and reuse have become higher and higher. [0003] In recent years, chlorine dioxide disinfection, ultraviolet disinfection and combined disinfection composed of several disinfection processes have developed rapidly from technical processes to practical applications in various places, and accumulated rich experience and operating data. However, each process has obvious defects and shortcomings. [0004] The disadvantages of the traditional disinfection method based on liquid chlorine include: [0005] 1) Liquid chlorine disinfection is prone to produce disinfection by-products, which ha...

AI Technical Summary

Problems solved by technology

[0005] 1) Liquid chlorine disinfection is prone to produce disinfection by-products, which has aroused widespread concern among people

[0006] 2) Liquid chlorine disinfection has the disadvantage of poor safety in the storage link and is prone to leakage

[0007] 3) Since the 1970s, due to the discovery that chlorine can form carcinogenic or disease-causing products with various substances in water, the application of this process has been limited

[0008] 4), high cost

[0011] 2), high cost

[0012] To sum up, although the current drinking water disinfection process has been widely used, the process maturity is not high, and there is no perfect drinking water disinfection treatment technology.
