Abstract
The present invention relates to a method for treating polluted water surfaces by using polyacrylamide. Firstly, polyacrylamide is directly sprayed onto a polluted water surface, and then upfloated dirt is removed. The polyacrylamide is powder or diluent, and the dilute concentration is 2%. The present invention researches new purposes of the polyacrylamide for treating the polluted water surface in wide area. The present invention has the characteristics that the cost of treating the water surface in wide area is low. Only less than 0.12 yuan is needed to treat the water of per cubic metre by using the polyacrylamide; the used method and equipment are simple and are easy to popularize. The polyacrylamide is directly and uniformly sprayed onto the water surface by a spraying instrument; adding any substance is not needed, and any manufacture equipment, combination equipment and moulding equipment are not needed. Thereby, the optimal treatment effect is reached by the simplest method. The epidemic situation extension of fishes or shrimps can be prevented, and the damage on the human body and livestock can not be created. Algae and organic substances in the polluted water can generate flocculation when encountering the polyacrylamide; the flocculation can be dredged for manufacturing fertilizers. The polyacrylamide is suitable for treating polluted water bodies of tanks, ponds, lakes, etc.
Description
Technical field
The present invention relates to a kind of water treatment method, particularly to the treatment process of wide-area polluted water surface.
Background technology
Along with development of modernization, many industrial pollutants and domestic pollutant are disposed in the water bodys such as lake surface, pond, and the lighter endangers the microorganism in the water, and weight person causes person poultry poisoning's injures and deaths.After the big area water surface is contaminated, higher because of the cost of water treatment, effect is not remarkable, good method never.
Existing polyacrylamide is a kind of macromolecular cpd, can be used for producing the additive of sugar, but simple operation of no use just can be applied to the way of the Pollution abatement of water body in large.
Technology contents
The present invention solves the big area water surface does not have cheapness, effective treating method after pollution technical problem.
Polyacrylamide of the present invention is handled the technical scheme of polluting water surface method, it is characterized in that:
A, polyacrylamide directly is sprayed on the contaminated water surface;
The dirt that b, removing are then floated.
Above-mentioned polyacrylamide is dry powder or diluent.
The concentration of above-mentioned polyacrylamide diluent is 0.1-10%, and the best is 2%.
The sprinkling amount of above-mentioned polyacrylamide is every m
3Sewage spray 0.5-2 litre, the best is 1 liter.
The above-mentioned contaminated water surface comprises pond water, lake water.
Beneficial effect: the present invention has studied the new purposes of polyacrylamide processing wide-area polluted water surface.Polyacrylamide is directly used in lake, the pool water surface, and then removes the floating on water pollutent.Its characteristics are as follows:
1, the processing costs of the big area water surface is cheap, and handling every cubic metre of water with polyacrylamide only needs below 0.12 yuan, very economical.
2, simple with polyacrylamide processing big area water surface method therefor and equipment, spraying device can be a special equipment, can be the atomizer of original agricultural chemicals, chemical fertilizer also, is easy to promote.Directly evenly be sprayed on the water surface with general spraying device, do not need to dash with any material,, reach best treatment effect with the easiest method also without any need for manufacturing, mixing, molding device.
4, polyacrylamide is a kind of additive that can be used in the sugar production, is a kind of safe material, can not cause the infringement of human body and animal health.
5, polyacrylamide has antibacterial ability, can prevent that the epidemic situation of fishes and shrimps from stretching.
6, algae in the sewage and organism run into polyacrylamide and promptly can produce flocculation, and pollutent can floatingly be gone up the water surface after flocculation, can fish for making fertilizer, has both cleaned water body, has utilized refuse again, can not cause new pollution.Be applicable to the improvement of contaminated water bodys such as lake, the pool.
Embodiment
Embodiment one: polyacrylamide (PAM) dry powder formulations is directly changed evenly be sprayed on the water surface, remove the floating on water dirt again.
Embodiment two: polyacrylamide thin up to 2%, evenly be sprayed on the water surface with atomizer, every m
3About 1 liter of sewage spray after several minutes, treats that the dirt cohesion floats, and salvages and goes on board, and makes fertilizer after drying.
Claims (5)
1, a kind of polyacrylamide is handled the method for polluting the water surface, it is characterized in that:
A, polyacrylamide directly is sprayed on the contaminated water surface;
The dirt that b, removing are then floated.
2, polyacrylamide according to claim 1 is handled the method for polluting the water surface, and it is characterized in that: described polyacrylamide is dry powder or diluent.
3, polyacrylamide according to claim 2 is handled the method for polluting the water surface, and it is characterized in that: the concentration of described polyacrylamide diluent is 0.1%-10%.
4, handle the method for polluting the water surface according to claim 1 or 2 or 3 described polyacrylamides, it is characterized in that: the sprinkling amount of described polyacrylamide is every m
3Sewage spray 0.5-2 litre.
5, handle the method for polluting the water surface according to claim 1 or 2 or 3 described polyacrylamides, it is characterized in that: the described contaminated water surface comprises pond water, lake water.
