Abstract
The present invention relates to a kind of preparation method of high dephosphorization amount diatomite adsorbing material, belong to field of material technology.Flyash and diatomite are stirred, ball milling, sieved to obtain ball-milled powder, and ball-milled powder is placed in Muffle furnace, activation, then is heated up, and insulation calcining, standing is cooled to room temperature, obtains roasting matrix powder；Weigh tetraethyl ammonium hydroxide solution, sodium hydroxide and sodium metaaluminate to be placed in beaker, stir to obtain matrix liquid, weigh deionized water Ludox, tetraethyl ammonium hydroxide solution and sodium oxide molybdena and be placed in beaker, stir to obtain modification liquid；Modification liquid, acetone, styrene maleic anhydride copolymer and 2 dimethylaminoethylamines are taken respectively, are stirred, and obtain mixing dropping liquid；Roasting matrix powder is added in modification liquid, ultrasonic disperse obtains dispersion liquid, mixing dropping liquid is added dropwise in dispersion liquid, then insulation reaction, standing are cooled to room temperature, filter filter cake and to wash, vacuum drying can be prepared into a kind of high dephosphorization amount diatomite adsorbing material.
Description
Technical field
The present invention relates to a kind of preparation method of high dephosphorization amount diatomite adsorbing material, belong to field of material technology.
Background technology
The system of global fresh water is transported to due to excessive nutrient causes outrophication risk to increase.The input of excessive nitrogen phosphorus causes
Surface water, which is degenerated, causes drinking water safety and ecosystem health problem so as to by global concern.Although in decades, point source
The control of pollution, which is administered, to be greatly improved, therefore the research pipe management in face source is oriented by emphasis.In industrialized country
In, most of face source desorption researchs show, scope is big, intermittent, row occurs because it is produced for pollution of area source caused by agricultural production
The features such as uncertainty when putting, turn into waters nutrition pollution source main at present.Chemical fertilizer that agricultural production uses, agricultural chemicals etc.
Nutrition leakage in goods and materials is the main factor that causes eutrophication, due to the leakage of fertilizer, arable land with water system be combined with
And rainwater transfer, rainwater carry the sewage containing high nutrition and are imported into surface water and groundwater, pollute its water quality.Moreover, with regard to mesh
Preceding global energy environment situation judges that, due to the scarcity and limitation of non-renewable energy resources, biomass energy is because of its circulation effect
Can CO that is high, and discharging2And the matter emissions that can pollute such as CO, HC, PM only have respectively it is original it is general even
Less etc. obvious advantage is as the outstanding figure in regenerative resource, by very big concern.But during manufacture bio-fuel, to environment
Bring certain harm.Wherein, the maximum effect to caused by water environment of the production to bio-fuel is to cause body eutrophication,
Due to can mainly be planted as the crop of bio-fuel in the soil of low nutrition or non-agricultural soil, so can largely make
Use fertilizer and pesticide.Therefore while alleviating energy crisis, the problem of also making global eutrophication, is more serious.Eutrophy dissolves
Wawter bloom now is shown as in lake, reservoir, is then red tide phenomenon in marine site.Investigation on Environment Management of Eutrophication both at home and abroad
Illustrate, the present situation of the ocean situation also allows of no optimist.From the 1960s, due to red tide phenomenon caused by the eutrophication of ocean just
The whole world is generally appeared in, has been one of global Oceanic disasters so far, during the decaying of red tide, release comes in and goes out vulcanization
Thing gas and toxin can polluted seawater, be that many still wants to biology and hidden flee from, so as to form in " dead band ".Such as U.S.'s Publishing Study
Report display, the Gulf of Mexico " dead band " phase size is equivalent to the Connecticut State in the U.S.；The Hangzhou Wan in China Zhejiang
Occur " dead band " of nearly 100 sq-km and 20 sq-kms respectively with the Communities of The Jinzhou Bay in Liaoning.In marine site
Sea grass bed can be the growth of the fish species with very high commercial value with biological support diversity and be ecosystems services
Hotbed, therefore be protect coastal ecosystems key.Eutrophication can cause fungi to grow and limit sunlight,
So as to cause the degeneration of sea grass even to disappear.In summary, it is exactly to administer rich battalion to repair one of important measure of water environment
Fosterization.In the absorbent extraneous nutrient of plant, a kind of minimum upgrowth situation for determining plant of content.Phosphorus is in algae molecule
Middle proportion is minimum, then, phosphorus is the key factor of algal grown.When the nitrogen surplus in water body, made by biochemistry
With nitrogen being made to be converted into the form of gaseous nitrogen, and overflowed from water body.P elements do not have common gas form, certainly
The circulation on right boundary belongs to appositional pattern, if being present in water body, can only just be circulated with different shape in water body, had with nitrogen cycle
Very big difference.Moreover, when the phosphorus content in every liter of water reaches 0.02mg, eutrophication is easy for occurring.In Curacao
Investigation with Bonaire finds that N is 0.91~2.4% in the general content of nutrient density in original sea grass bed blade and P is
Between 0.05~0.18%, and in the system of eutrophication, the content of leaf nutrient concentration is that N is 1.87~3.02%, and P is
0.14~0.70%.Also, the data and SUMMARY OF THE RELEVANT LITERATURE of monitoring illustrate, the nutrient content of blade in sea grass bed（Especially
P）, be typically due near source of nutrition and raise, so generally may be used as be nutrition pollution important indicator.Due in water
Whether the conduct containing phosphorus concentration, which eutrophication occurs, is put into pacing factor, then reducing the concentration of phosphorus just turns into alleviation eutrophication
Breach.
