Description
Technical field
The invention belongs to purified water fields, and in particular to a kind of water dispenser water purifying column.
Background technique
With the development of national economy, requirement of the people to quality of life is gradually increased, safe drinking water also increasingly by
Pay attention to, therefore the water dispenser from waterworks pipe network is also widely used.Daily water dispenser relatively mostly uses bottled water source, out
It examines, can guarantee the quality under the conditions of not breaking a seal three months or so time, to ensure that routine drinks requirement by severe quality when factory
Safety.But behind Kaifeng, since water dispenser can constantly suck air supplement in the process of water release, so that the bacterium in atmosphere
It follows and is mixed into water dispenser tank and forms pollution, the water purification quality retention time shortens rapidly, often uses less than 7 day time and will send out
Content of microorganisms is exceeded in existing water, continues to drink and brings hidden danger to human health, gives it up and be a kind of wasting of resources, this
Practical application defect is badly in need of effective technology means and measure is overcome.
Traditional drink water purifying method is that activated carbon adsorption and film filter.But in use, on active carbon
The increase of noxious substance amount, adsorption capacity decline, effluent quality deterioration need to be replaced frequently, but the time replaced is difficult
To grasp.For film filtering, suspended matter and scale in water are easy to block film, need often to clean.In addition, bacterium energy
It is enough to be bred rapidly using the organic matter for being attached to active carbon and filter membrane surface as food, jeopardize the health of people.Due to
TiO2 photocatalysis drinking water is a kind of completely new purification method, and Organic substance in water can be resolved into CO2 and water, and makes a huge sum of money in water
Belong to ion reduction removal, secondary pollution will not be generated, but since the content of organics in tap water is very low, water stops in decontaminating column
Stay the time shorter, photocatalysis efficiency is low, it is difficult to water quality after processing be made to reach the standard directly drunk.
Summary of the invention
The purpose of the present invention is to overcome the defects in the prior art, provides a kind of water dispenser water purifying column.
The present invention to achieve the above object, using following technical scheme:
A kind of water dispenser water purifying column exists including shell, the water inlet being arranged on the shell, water outlet, setting
The ultraviolet lamp tube of the enclosure interior, for the ultraviolet lamp tube partition and that the shell is arranged in is intracorporal
For crossing the filler of drainage；
The filler includes modified support and the active silver ion that is supported on the modified support；Described changes
Property carrier is the carrier being modified by butyl titanate and silane coupling agent in porous carrier surface；Butyl titanate dosage
For the 0.1-5% of the porous carrier quality；Silane coupling agent dosage is the 0.1-1% of the porous carrier quality；Described
The dosage of active silver ion is the porous carrier quality 0.1-5%.
The porous carrier is one of molecular sieve or silica.
The silane coupling agent is one of KH580 or KH590.
The filler is prepared using following manner:
1) modification of carrier: by porous carrier plus the water of 10 times of mass parts, slurry is obtained；Butyl titanate is molten
Solution is added dropwise in the slurries of stirring into the dehydrated alcohol of its 5 times of quality, continues stirring at least 1 hour after being added dropwise to complete,
Separation is filtered later, and gained filter cake is dried at 120 DEG C, obtains preliminary modified support；By preliminary modified support dispersion 50%
In ethanol water, aequum silane coupling agent is added and obtains tentatively being modified slurries, 50~60 DEG C are warming up under stirring
And hydrochloric acid is added and adjusts in the pH value to 2~4 ranges of slurries C, sample is filtered after continuing stirring at least 6 hours and is separated, gained
Filter cake dries to arrive modified support at 120 DEG C；
2) active component is uploaded: the desired amount of silver nitrate aqueous solution being impregnated into step 1) using initial impregnation method obtains
Modified support on, dry at 120 DEG C, then transfer the sample into tube furnace later, be warming up to 350 in a hydrogen atmosphere
DEG C reduction at least 2 hours, being cooled to room temperature to sample with volume ratio is 1%O2/N2Gaseous mixture purges at least 2 hours and obtains filler.
The case top is provided with dismountable cover board and replaces filler to open the shell.
Compared with prior art, the beneficial effects of the present invention are:
The application is deposited on the butyl titanate of porous carrier surface under ultraviolet light using photocatalyst catalyst
The TiO2 being decomposed to form, since its surface generates light induced electron-hole pair, photohole has strong oxidation, light induced electron
With strong reducing action.By porous carrier adsorb organic matter diffuse to the surface TiO2, by photohole oxygenolysis be CO2 and
Water.Heavy metal ion is restored by light induced electron on the surface TiO2 and is therefrom removed, and is deposited on the activity silver of porous carrier surface
Ion makes bacterium and harmful substance in water be killed that tap water is made to reach degree capable of direct drinking.
Meanwhile the surface of porous carrier can be deposited on after silane coupling agent hydrolysis, the sulfydryl of end can be with silver ion network
It closes to prevent the aggregation and sintering of active silver ion.
