The invention can effectively remove fluorine at 70-90%.
Description
Technical field
The present invention relates to a kind of filter core, particularly relate to a kind of filter core of removing fluorine in the drinking water and preparation method thereof.
Background technology
Along with developing rapidly of industry and agricultural, the water resource of China has been suffered heavy damage.Increasing industrial wastewater discharge has destroyed our ecological environment in rivers, lake.The discharging wantonly of the extensive application of agricultural chemicals, pesticide and house refuse causes the quality of groundwater variation, and causes producing in the water a lot of harmful materials.Water pollutes more and more becomes the severe problem that influences people's life.
Fluorine is one of human life activity's trace elements necessary, needs the fluorine of 1.0～1.5mg everyone every day approximately.The source of fluorine mainly contains nature and two kinds of artificial modes.A spot of fluorine has certain effect to health especially tooth is firm.Over nearly 60 years, the industrial production activity becomes the main artificial source of fluoride in the underground water.Produce phosphate chemical fertilizer, dissolved aluminum, glassware and bake bricks, industrial process such as steel-making all can discharge fluoride, thereby cause a lot of local underground water fluorinated volumes to exceed standard.The drinking water fluorinated volume is greater than 1,000,000/time, and tooth enamel can be destroyed, and gloss disappears, and ash or yellow spotting occur, i.e. glaze tooth or mottling of teeth; Reach at 8/1000000ths o'clock, will make bone and kidney suffer infringement; Reach at 10/1000000ths o'clock, can cause bone malformation, simultaneously with nervous symptoms, maimed type fluorosis of bone that Here it is.Drinking-water is the main source of fluorine, and in high fluorine geographical environment, human body is because of the fluorine of long-term excess intake, body accumulation and cause fluorine poisoning.In China, some areas such as capital, Tianjin, Ji, Henan, Shandong, Shanxi, Shan, sweet, peaceful, three provinces in the northeast of China and Inner Mongol are exactly high fluoride area (fluorinated volume is above 1.5 milligrams in every premium on currency).Often drink these local underground water, can be detrimental to health, cause various fluorine poisonings.
Present stage, along with growth in the living standard, people's health care consciousness is also more and more stronger.Only the water through the waterworks sterilization does not have removal effect to fluorine.Though the various water quality treaters that occur on the market have the improvement effect to the overall purification of water quality, but still can not solve the fluorine-containing pollution problem in high fluorine area well.Fluoride pollution remains our water treatment difficult problem of puzzlement.
Traditional defluorination method mainly contains the precipitation method, absorption method and hyperfiltration etc.The precipitation ratio juris is to add medicament in former water, formation fluoride precipitation, separate through solid then and reach the purpose of removing fluorine ion, the general medicament that adopts has lime, carbide slag, dolomite or alum etc., this method treated water generally can not reach guidelines for drinking water quality, also need to carry out advanced treating, and the water that some chemicals treatment is crossed also needs to carry out pH value adjusting etc., process more complicated again.Absorption method is to utilize fluorine to select sorbing material to remove by filter fluoride, and its basic mechanism is a kind of ion-exchange or adsorption reaction.This method operation and maintenance technology are higher, and expense is bigger, only are applicable to the advanced treating regional or fluorinated water after preliminary treatment fluorine content drops to 1.5mg/L～3.0mg/L that fluorinated volume is low.Reverse osmosis technology is a kind of membrane separation technique, its principle is under the pressure effect that is higher than the solution infiltration, the selection of the pellicle by other material effect of damming does not separate harmful substance by only allowing water to see through, this method depends on the pH value of former water to a great extent, apparatus expensive is made water cost height, and the water rate of recovery is low, power consumption is bigger, is generally used for industry and makes pure water.
Summary of the invention
The present invention is in order to address the above problem, a kind of filter core that is used to purify water is provided, it not only can remove other harmful substance in the water, improve water quality, be particularly useful for fluorine-containing higher water source, can play good clean-up effect, effectively improve the water quality in the high area of fluorinated volume fluorine, reduce the fluorine poisoning phenomenon, improve high fluorine area people's health.
An object of the present invention is to provide a kind of filter core of removing fluorine in the drinking water.
Another object of the present invention provides the preparation method of the filter core of fluorine in the described removal drinking water.
