Description
Technical field
The present invention relates to the application as fall fluorine material in water processes of a kind of Si-P crystal.
Background technology
Current fall fluorine filtrate is negative resin filter element, active carbon filter core, activated alumina filter element or di
Calcium filter elements etc., these filter elements are the most expensive, and cost is high, and need often regeneration, the effect of fall fluorine
Bad.Domestic fall fluorine is mainly some large-scale water factories and water source carries out dropping fluorine, and the device so dropping fluorine compares
Huge, crucial needs often regenerates, service difficulty, and cost is higher, inadaptable in endemia fluorosis remote villages
Promote widely.
Summary of the invention
The invention provides the application as fall fluorine material in water processes of a kind of Si-P crystal, it not only can drop
The cost that low water processes, and low price, low cost, fluoro droping effect is good.
Present invention employs techniques below scheme: a kind of Si-P crystal in water processes as the application dropping fluorine material.
Described Si-P crystal intramolecular is by the phosphorus atoms of more than 2, with alkali metal or alkaline earth metal atom and oxygen
The material general name that atom combines.There is sizable specific surface area, have sizable absorption affinity and adsorption capacity.
When fluorinated water is through filter material, fluorine will be adsorbed on the screen work of material by the surface adsorption field of force, is formed
It is not melted into the fluorochemical molecule group of water.Removed it by flushing.
The method have the advantages that the Si-P crystal of the present invention has sizable absorption affinity and absorption appearance
Amount, when fluorine will be adsorbed on the screen work of material by fluorinated water through Si-P crystal filtrate, the surface adsorption field of force,
Forming the fluorochemical molecule group not being melted into water, removed it by flushing, water-borne glue body granule is had by Si-P crystal
Having peptizaiton, the colloid that can and be deposited on tube wall combines, or forms network with the ion being attached on tube wall
Closing or chelating, make crystal structure change, Si-P crystal not only has the strongest defluoridation, and permissible
Exceeding standard the water yield of water according to processing fluorine, the loading of Si-P crystal is increased or decreased, effect of fluorine removal is big simultaneously
Big strengthening, 1.5KG Si-P crystal can process fluorine and exceed standard water about 500T, does not in use have constantly
Reduction and regeneration, low price, low cost, fluoro droping effect is good.
Detailed description of the invention
The invention provides the application as fall fluorine material in water processes of a kind of Si-P crystal.Si-P crystal, chemistry
Name: Quadrafos, molecular formula: G-PHOS.Si-P crystal intramolecular is by the phosphorus atoms of more than 2, with alkali gold
The material general name that genus or alkaline earth metal atom and oxygen atom combine.There is sizable specific surface area, have quite
Big absorption affinity and adsorption capacity.When fluorinated water is through filtration core, fluorine absorption will be existed by the surface adsorption field of force
On the screen work of material, form the fluorochemical molecule group not being melted into water, removed it by flushing.It is right
Water-borne glue body granule has peptizaiton, and the colloid that can and be deposited on tube wall combines, or and is attached to tube wall
On ion form complexation or chelating, make crystal structure change.
The present invention further illustrates Si-P crystal by following experimental data and carries out dropping fluorine operation in water treatment procedure
Effect produced by.
