Abstract
The invention discloses use of silicon phosphate crystals as a material for removing fluorine in water treatment. The silicon phosphate crystals have high adsorption force and adsorption capacity, and when fluorine-containing water flows through a silicon phosphate crystal filter material, a surface adsorption force field adsorbs fluorine on a lattice of the material to form water-insoluble fluoride molecular groups, the water-insoluble fluoride molecular groups are removed through washing; the silicon phosphate crystals have the effect of dispersing colloid particles in water, and can be combined with colloids on the tube wall, or complexed or chelated with ions adsorbed on the tube wall, so that the crystal structure is changed; the silicon phosphate crystals have high fluorine removing effect, the filling amount of the silicon phosphate crystals can be increased or reduced according to the amount of water with overproof fluorine to be treated, and the fluorine removing effect is greatly enhanced, namely 1.5kg of silicon phosphate crystals can treat about 500 tons of water with overproof fluorine; and in the using process, continuous reduction and regeneration cannot happen, and the silicon phosphate crystals have low price, low cost and good effect of removing the fluorine.
Description
Technical field
The present invention relates to the conduct in water treatment of a kind of Si-P crystal and fall the application of fluorine material.
Background technology
The present fluorine filtrate that falls is negative resin filter core, active carbon filter core, activated alumina filter core or calcium phosphate powder filter core etc., and these filter cores not only cost an arm and a leg, the cost height, and need often regeneration, the effect of falling fluorine is bad.The domestic fluorine that falls mainly is that fluorine falls to the water source in some large-scale water factories, and the device that falls fluorine like this is huger, and crucial the needs often regenerates, the service difficulty, and cost is than higher, and incompatibility is promoted widely in the outlying rural area of endemia fluorosis.
Summary of the invention
The invention provides the conduct in water treatment of a kind of Si-P crystal and fall the application of fluorine material, it not only can reduce the cost of water treatment, and low price, and cost is low, and fluoro droping effect is good.
The present invention has adopted following technical scheme: the application of fluorine material falls in the conduct in water treatment of a kind of Si-P crystal.
Described Si-P crystal intramolecularly is by the phosphorus atom more than 2, with basic metal or alkaline earth metal atom and Sauerstoffatom bonded material general name.Have sizable specific surface area, sizable adsorptive power and loading capacity are arranged.When fluorinated water process filtrate, the surface adsorption field of force will be adsorbed on fluorine on the screen work of material, forms the fluorochemical molecular grouping that is not melted into water.By washing with its removal.
The present invention has following beneficial effect: Si-P crystal of the present invention has sizable adsorptive power and loading capacity, when fluorinated water process Si-P crystal filtrate, the surface adsorption field of force will be adsorbed on fluorine on the screen work of material, form the fluorochemical molecular grouping that is not melted into water, by washing with its removal, Si-P crystal has dissemination to water-borne glue body particle, can and be deposited in the colloid combination on the tube wall, perhaps form complexing or chelating with the ion that is attached on the tube wall, crystalline structure is changed, Si-P crystal not only has the very strong fluorine effect of falling, and can handle the exceed standard water yield of water of fluorine according to need, increase or reduce the loading level of Si-P crystal, the effect of defluorination strengthens greatly simultaneously, and the 1.5KG Si-P crystal can be handled the fluorine about 500T of water that exceeds standard, constantly reduction and regeneration in use can not appear, low price, cost is low, and fluoro droping effect is good.
Embodiment
The invention provides the conduct in water treatment of a kind of Si-P crystal and fall the application of fluorine material.Si-P crystal, chemical name: poly-phosphate, molecular formula: G-PHOS.The Si-P crystal intramolecularly is by the phosphorus atom more than 2, with basic metal or alkaline earth metal atom and Sauerstoffatom bonded material general name.Have sizable specific surface area, sizable adsorptive power and loading capacity are arranged.When fluorinated water process filter core, the surface adsorption field of force will be adsorbed on fluorine on the screen work of material, forms the fluorochemical molecular grouping that is not melted into water, by washing its removal.It has dissemination to water-borne glue body particle, can and be deposited in the colloid combination on the tube wall, perhaps forms complexing or chelating with the ion that is attached on the tube wall, and crystalline structure is changed.
