Description
Technical field
The invention belongs to the drinking water defluorination process field, be specifically related to a kind of load aluminum ions bone black defluorinating agent system and its preparation method.
Background technology
The fluorine poisoning that high fluorine groundwater causes is worldwide drinking water type endemic disease, and the whole world has 25 countries to have analogue approximately.China is one of country that the fluorine poisoning situation is the most serious in the world, and the drinking water type endemic fluorosis is distributed in 29 provinces of China, and by the end of the year 2005, China also has 4,595 ten thousand urban residents still to be subjected to the puzzlement that fluoride exceeds standard in the drinking water.China planning is the Eleventh Five-Year Plan period solving 3,811 ten thousand urban residents' high-fluorine water problem.
Drinking water defluorination method commonly used at present comprises coagulant sedimentation, absorption method, electroosmose process, hyperfiltration etc., and wherein the absorption method operation is simple relatively, water producing cost is lower.Bone black is a kind of drinking water tradition de-fluoridation adsorbent, its chemical composition mainly is a hydroxyapatite, when contacting with water, bone black can adsorb fluorine ion or fluoride from water, thereby the concentration of fluoride in the reduction water, the World Health Organization classifies the bone black absorption method as first-selection recommendation technology that high-fluorine water is handled in the low developed area.
Compare with traditional drinking water defluorination adsorbent, bone black has higher adsorption capacity, but compares with novel drinking water de-fluoridation adsorbents such as the modified resin of present appearance, modification of chitosan, and the adsorption capacity of bone black is lower, and the space improves.
Summary of the invention
At the lower problem of the adsorption capacity of bone black, the present invention proposes the preparation method and the aluminum ions bone black defluorinating agent of resulting load thereof of the aluminum ions bone black defluorinating agent of a kind of load, to improve the adsorption capacity and the serviceability of carrying aluminium bone black defluorinating agent.
The preparation method of the aluminum ions bone black defluorinating agent of a kind of load that the present invention proposes is characterized in that described method is that bone black is put into aluminum salt solution, and vibration makes load aluminium ion on the bone black, and its concrete steps are as follows:
(1), puts into the aluminum salt solution of certain volume with the bone black of certain mass;
(2) bone black aluminum salt solution mixture is vibrated under certain condition certain hour;
(3) bone black is taken out, after the clear water flushing, place under the normal temperature dry.
In above-mentioned preparation method, the described aluminum salt solution of step (1) is aluminum nitrate solution or other aluminum solutions that is suitable for.
In above-mentioned preparation method, the mass ratio of described bone black of step (1) and aluminum salt solution is 1: 8～1: 12.
In above-mentioned preparation method, the aluminium ion concentration in the described aluminum nitrate solution of step (1) is not less than 1.2g/L.
In above-mentioned preparation method, the described oscillating condition of step (2) is: bone black needs fully to mix with solution in the oscillatory process, and duration of oscillation is no less than 24 hours, and the temperature of mixture remains on 20 ℃～40 ℃ during vibration.
In above-mentioned preparation method, the described aluminum salt solution of step (1) is liquor alumini chloridi, Burow's Solution or aluminum citrate solution.
The batch (-type) adsorption test shows, year aluminium bone black defluorinating agent that method of the present invention is prepared, adsorption capacity is higher more than 60% than general bone black defluorinating agent, 2 times of the rate of adsorption the chances are general bone black, the interference that can effectively resist chlorion common in the general high fluorine groundwater, sulfate ion, calcium ion simultaneously.It is used in the high fluorine groundwater is the area of drinking water source, can guarantee DRINKING WATER safety effectively, reduces water producing cost simultaneously, reduces the workload of water supply project regular maintenance.
