Abstract
The present invention relates to a kind of preparation methods of heavy metal containing sewage adsorbent material, comprising the following steps: mixes sodium aluminosilicate, polyacrylamide, sodium acetate, resorcinol, sodium bicarbonate, pectin, obtains primary mix；The primary mix is added to the water stirring, sub-mixtures are obtained；Under oil bath heating for a period of time by the sub-mixtures, then natural cooling, obtains whole grade mixture；The whole grade mixture is calcined, after a period of time, then grinds to obtain sewage adsorbent material.Sewage adsorbent material prepared by the present invention is good to commercial metal heavy metal in waste water adsorption effect, and processing waste water cost is cheaper, has good economic benefit and environmental benefit.
Description
Technical field
The present invention relates to environment protection field, specially a kind of preparation method of heavy metal containing sewage adsorbent material.
Background technique
Heavy metal pollution refers to the pollution caused by water body and agricultural land soil environment of the industrial wastewater containing plurality of heavy metal.
Heavy metal in water environment is very harmful to human health and ecological environment, such as heavy metal Hg, into body after will directly sink
Enter liver, directly destruction brain eyesight nerve；Heavy metal lead is more toxic, and is damaged to the neural plate of fetus, is caused old
The diseases such as dementia, brain death；Heavy metal chromium will cause human limb numbness, insanity；Metalloid arsenic, it will lead to skin
Pigment deposition, abnormal keratinization；Cadmium will lead to hypertension and cardiovascular and cerebrovascular disease, destroys bone calcium, causes renal dysfunction.With much money
Belong to pollution problem and exceeded normal range (NR), is directly detrimental to health, and environmental quality is caused to deteriorate.Therefore it needs constantly more
New technology handles the heavy metal pollution problem got worse.
Summary of the invention
The shortcomings that for the above-mentioned prior art, the present invention provide a kind of preparation method of heavy metal containing sewage adsorbent material.
The present invention solves above-mentioned technical problem and uses a kind of following technical scheme: preparation side of heavy metal containing sewage adsorbent material
Method, comprising the following steps:
(1) by sodium aluminosilicate, polyacrylamide, sodium acetate, resorcinol, sodium bicarbonate, pectin respectively according to 60~70
Parts by weight, 20~25 parts by weight, 10~20 parts by weight, 30~40 parts by weight, 10~20 parts by weight, 30~45 parts by weight are mixed
It closes, obtains primary mix；
(2) primary mix is added to the water stirring, obtains sub-mixtures；
(3) by the sub-mixtures under oil bath heating a period of time, then natural cooling, obtains whole grade mixture；
(4) the whole grade mixture is calcined, after a period of time, then grinds to obtain sewage adsorbent material.
Preferably, water described in step (2) is deionized water.
Preferably, oil bath temperature is 120 DEG C~140 DEG C in step (3), 1~2h is heated.
Preferably, in step (4), when calcining, is passed through nitrogen as protective gas, calcination temperature is 200 DEG C~
300 DEG C, calcine 100~120min.
The invention has the following advantages over the prior art: sewage adsorbent material prepared by the present invention is to a huge sum of money in sewage
It is good to belong to ionic adsorption effect, adsorbent material can be enhanced to the adsorption capacity of heavy metal ion by calcining, while the adsorbent material
It also can be recycled, economize on resources；Raw material sources of the present invention are extensive, low in cost；Preparation method of the present invention is simple, operation side
Just, it is easy to accomplish industrial-scale production；It is cheaper to handle waste water cost, there is good economic benefit and environmental benefit,
Social benefit is good.
