A kind of method and system of plasma ozone chlorination drinking water
Technical field
The present invention relates to ozone application field, the method for more particularly to a kind of plasma ozone chlorination drinking water and it is
System.
Background technology
With the continuous improvement and the continuous enhancing of environmental consciousness of people's living standard, quality and dirt to drinking water quality
Water process and the standard of reuse require also more and more higher.
The combination type sterilizing that disinfection by chlorine dioxide, disinfection by ultraviolet light and several sterilization process are constituted in recent years, from technology
Technique has obtained quick development, has been also accumulated from rich experience and service data into the practical application of various regions.But each work
Skill has obvious shortcomings and deficiencies.
Disinfection way of the tradition based on liquid chlorine, its shortcoming includes:
1), liquid chlorine disinfection be also easy to produce DBPs, cause the generally worry of people.
2), liquid chlorine disinfection storage link have the shortcomings that security is poor, easily leak.
3), since the 1970s, because it is found that chlorine can form the production of carcinogenic or pathogenic change with many kinds of substance in water
Thing, causes the technique to start to be restricted in application.
4), cost it is high.Because disinfection by chlorine dioxide exists unstable and greatly must with volatile shortcoming, thus in consumption
Palpus making in site, adds use cost.Although having enough precaution measures in system design and operation, but still it should be noted equipment
Performance and safety operation.
The major defect of disinfection by ultraviolet light includes:
1), Disinfection Effect it is big by the influence of water quality, especially suspension, turbidity, design major parameter is referred to as ultraviolet penetrance.
2), cost it is high.Because sewage water outlet penetrance differs greatly, when penetrance is reduced to 50% from 60%, it is necessary to
Ultraviolet dosage to double, the configuration of same equipment and operating cost also increase with times;On the other hand, disinfection by ultraviolet light
Need import equipment one-time investment higher.
In summary, though current Disinfection Processes in Drinking Water Treatment is widely used, and technical maturity is not high, do not have also
A kind of perfect drinking water disinfection technology occurs.So in order to improve drinking water quality conscientiously, livelihood issues are effectively solved,
The drawbacks of needing effectively to solve present in existing sterilization process, improves drinking water quality.
