UF membrane filtering module 105 is filtered processing using RO reverse osmosis membrane equipment, in further embodiments, UF membrane filter module
Block 105 is filtered processing using device for ultrafiltration membrane.
In second of filtration treatment, booster water pump, a side are arranged between active carbon filtering module and UF membrane filtering module
Face meets the pressure requirements of UF membrane filtering module 105, realizes its filtering function；On the one hand make filter after water outlet with have pressure condition into
Enter pressure water container, when user's water consumption is smaller, it can be achieved that only relying on the water supply of pressure storage container, reduces equipment start-stop
Number, prolongs the service life.
Step S104, water after filter stores
By step S103, treated that water after filter is stored in pressure water container.
Step S105, second of advanced oxidation disinfection treatment
The water after filter that pressure water container flows out is carried out second by ultraviolet light catalyzing titanium dioxide chlorination equipment
Advanced oxidation disinfection treatment, the pathogenic microorganism for breeding to water after filter inactivate disinfection.
For by process such as primary filtration, the disinfection treatment of first time advanced oxidation and second of filtration treatments
Water afterwards cannot reach 100% removal of the pathogenic microorganisms such as bacterium, virus, and water after filter is stopped in pressure water container
Certain time is stayed, the pathogenic microorganisms such as bacterium, virus breed breeding again, according to an embodiment of the invention, in system water outlet
The second advanced oxidation disinfection unit is arranged in front end, to the processing of the water outlet of pressure water container further oxidation sterilizing, it is ensured that processing
Water afterwards enters user with high-quality, high standard.
According to an embodiment of the invention, presetting water consumption threshold value to pressure water container, preset when user's water consumption is less than
When threshold value, directly supplied water after step S105 processing from the water outlet of water purification system to user by pressure water container.
When user's water consumption is greater than preset threshold, the water inlet valve of water purification system is opened, through step S101 to step
After S105 processing, supplied water from the water outlet of water purification system to user.
The present invention disinfects unit by the way that advanced oxidation is arranged in water inlet front end, can be greatly decreased into active carbon mistake
The microorganism total amount for filtering module achievees the purpose that control active carbon filtering module microorganism total amount, is able to extend active carbon module
With the service life of UF membrane filtering module, reduce the expense investment of family and enterprise, reduce to filter element maintenance, cleaning or
Person's replacement.
The present invention arranges booster water pump between active carbon filtering module and UF membrane filtering module, is on the one hand UF membrane
The offer of module meets the pressure of filtering, on the other hand by the water after UF membrane modular filtration to there is pressure condition to enter pressure storage
Water container reduces equipment start-stop number, extends when user's water consumption is smaller, it can be achieved that only relying on pressure water container water supply
Service life.
The present invention disinfects unit, the disease not up to standard to UF membrane filtering module in water outlet front end setting advanced oxidation
The pathogenic microorganism bred in pathogenic microorganism, pressure water container is disinfected again, guarantees the high standard supply of water quality.
In conjunction with the explanation and practice of the invention disclosed here, the other embodiment of the present invention is for those skilled in the art
It all will be readily apparent and understand.Illustrate and embodiment is regarded only as being exemplary, true scope of the invention and purport are equal
It is defined in the claims.
