Abstract
The invention discloses an Attapulgite defluorination agent, wherein the Attapulgite defluorination agent comprises active Attapulgite clay, edible alum, calcium oxide, calcium sulfate and trichloroiminocyanuric acid. The preparation comprises charging Attapulgite defluorination agent into high-fluorine water, agitating to start the reaction between the Attapulgite defluorination agent and the fluorine in water, producing calcium fluoride, generating flocculation and carrying out rapid deposition, thus separating fluorine from water. The filtered clean water can be used for drinking.
Description
Technical field:
The present invention relates to engineering of water treatment, be specifically related to a kind of attapulgite defluorination agent.
Background technology:
Pertinent data according to investigations, present national rural area have more than 6,300 ten thousand people's tap water fluorine contents to surpass drinking water sanitary standard, the long-term drinking water of high fluorine content, and the lighter forms dental fluorosis, and weight person causes osteoporosis, ostealleosis, even paralyses disability.Generally make the no positive effect that heals with medicine because of drinking these illnesss that water of high fluorine content causes, often bring heavy burden, cause family's poverty to family.In the fluorine lesion, because dental fluorosis, " bucket circle pin ", bow-backed disease take place repeatedly, influence directly that the teenager enters a school, joins the army, employment and marriage.Some places villager height has only 0.8～1.4 meter, " short person village " occurred, and the villager is bearing the huge misery of physiology and psychology.
China's drinking water sanitary standard regulation, fluorine content in the Drinking Water, every liter should not surpass 1.0 milligrams, and the substandard water of long-term drinking is easily sent out dental caries, is higher than standard and then can suffers from the fluorosis illness.
The content that reduces fluorine in the water of high fluorine content can have several different methods, but most technical sophistication, cost is higher.
Chinese patent grant number CN1025954C, Granted publication day is on September 21st, 1994, name is called " fluorinated water treatment process ", it discloses, and " a kind of treatment process of fluorinated water; it adopts the method for fixed bed flyash absorption can make high-fluorine drinking water reach the following sanitary standard for drinking water of fluorine-containing 1mg/L adopts slurry attitude bed absorption method can make the trade effluent of the fluorine-containing 700-1000mg/L of phosphate fertilizer plant reach the following emission standard of fluorine-containing 20mg/L.Fluorine-containing ash can be used as the preparation building block or brick can not cause secondary pollution, thereby reaches the purpose of the treatment of wastes with processes of wastes against one another.This method and existing lime precipitation mutually specific investment only be its 22%, cost only be its 69%.”
The weak point of foregoing invention is, adopt " method of fixed bed flyash absorption ", Treatment of High Fluoride Drinking Water, from above-mentioned patent document, know, can reach sanitary standard for drinking water, still, in reality is promoted, it is Drinking Water that people can not purify water of high fluorine content with " flyash ", this treatment process also beyond affordability.
Summary of the invention:
The objective of the invention is to overcome weak point in the prior art, a kind of cheap, easy to use, attapulgite defluorination agent that defluorination effect is good is provided.
Attapulgite defluorination agent is made up of activated attapulgite, edible alum, calcium oxide, calcium sulfate and trichloroisocyanuric acid.
Activated attapulgite is to select the high-quality attapulgite clay for use, after acidification, make it have stronger adsorptive power, edible alum is a kind of good flocculation agent, calcium oxide and anhydrous calciumsulphate can with the fluorine in the water, generate Calcium Fluoride (Fluorspan), activated attapulgite and edible alum adsorb Calcium Fluoride (Fluorspan), produce flocculation and carry out rapid precipitation, fluorine is separated from water, trichloroisocyanuric acid is used for sterilization.
The present invention is achieved by following technical proposals:
1, the batching of attapulgite defluorination agent comprises following component by weight percentage:
Attapulgite clay 55～80%, edible alum 2～8%, calcium oxide 5～20%, anhydrous calciumsulphate 5～15% and trichloroisocyanuric acid 2～10%.
2, with in the attapulgite clay, edible alum, calcium oxide, anhydrous calciumsulphate and the trichloroisocyanuric acid input mixing and blending machine that prepare, after stirring, be packaged as finished product.
3, using method: attapulgite defluorination agent added in the water of high fluorine content stir, the fluorine reaction in attapulgite defluorination agent and the water generates Calcium Fluoride (Fluorspan), produces flocculation and also carries out rapid precipitation, and fluorine is separated from water, and getting clarifying water after filtering is Drinking Water.
Attapulgite defluorination agent of the present invention, can make the content of fluorine in the water of high fluorine content, be reduced to below the 1mg/L, reach country's " drinking water sanitary standard ", be applicable to collecting water supply system and the separate water supply that drink for life in town and country, also be applicable to fluorine-containing industrial sewage processing.
Embodiment:
The invention will be further described below in conjunction with embodiment:
1, the batching of attapulgite defluorination agent comprises following component by weight percentage:
Attapulgite clay 65%, edible alum 5%, calcium oxide 15%, anhydrous calciumsulphate 10% and trichloroisocyanuric acid 5%.
2, with in the attapulgite clay, edible alum, calcium oxide, anhydrous calciumsulphate and the trichloroisocyanuric acid input mixing and blending machine that prepare, after stirring, be packaged as finished product.
Claims (2)
1, a kind of attapulgite defluorination agent is characterized in that, attapulgite defluorination agent is made up of activated attapulgite, edible alum, calcium oxide, calcium sulfate and trichloroisocyanuric acid.
2, a kind of attapulgite defluorination agent according to claim 1, it is characterized in that, the defluorinating agent batching of Attapulgite comprises following component: attapulgite clay 55～80%, edible alum 2～8%, calcium oxide 5～20%, anhydrous calciumsulphate 5～15% and trichloroisocyanuric acid 2～10% by weight percentage.
