Abstract
The present invention relates to a kind of preparation methods of sewage treating material, comprising the following steps: mixes alpha-cyclodextrin, polyacrylamide, sodium bicarbonate, calcium oxide, aluminium oxide, magnesia, sodium hydroxide, kaolin, obtains primary mix；The primary mix is added to the water stirring, sub-mixtures are obtained；The sub-mixtures are heated to a period of time in autoclave, then vacuum cooled, obtains whole grade mixture；The whole grade mixture is dry, and grinding obtains sewage treating material.For sewage treating material prepared by the present invention to commercial metal heavy metal in waste water high treating effect, 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 sewage treating 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 sewage treating material.
The present invention solves above-mentioned technical problem and uses a kind of following technical scheme: preparation method of sewage treating material, packet
