Abstract
The present invention relates to polyvinyl acetate material, its characteristics are: 55-65% polyvinyl acetate is used as basic structural body, 30-40% natural cellulose is ground to 80-100 mesh powder which is mixed uniformly with silieic acid, then combined with polyvinyl acetate basic structural body together and put into puffing machine to puff, it makes the nature cellulose and silicis acid permeate into polyvinyl acetate structural body to form porous cubic body. It reduces floor area and cost, conforms with national standard and is long in service life.
Description
The present invention relates to a kind of material, be specially a kind of poly vinyl acetate material.
Owing to reasons such as municipal sewage system, trade effluent, farmland fertilizations, nitrogen, phosphorus, organic composition in these regional waters (river, lake, coastal marine site) sharply increase, and water quality is polluted, and is unfavorable for environment protection, is unfavorable for national economy sustainable development.The method of removal organic composition commonly used and nitrogen, phosphorus has physico-chemical process and biological processes method.The biological processes method has comprised that then nitration reaction, denitrification reaction constitute, and nitration reaction is a key point.We know as long as quicken nitration reaction speed, can reduce the quantities that biological chemistry is removed nitrogen, phosphoric widely.Nitrifier is slow than the formation speed of the required bacterium of oxidation operation, and to reach certain density nitrifier required time long for this reason, guarantees to improve the concentration of nitrifier.
The object of the present invention is to provide and a kind ofly can in sewage, remove the nitrogen phosphate material.
The object of the present invention is achieved like this: it is by 55-65%, polyvinyl acetate (PVA) is the basic boom body, wearing into 80-100 order powder and the silicic acid 4-10% back that stirs with the natural cellulose of 30-40% enters bulking machine simultaneously with polyvinyl acetate (PVA) basic boom body and carries out expanded, make natural cellulose and silicic acid all penetrate into polyvinyl acetate (PVA) framework body inside, make little side's body 10 of porous 8 shapes.Hole 8 on little side's body 10 is 0.10-0.20mm (sponge shape hole), and polyvinyl acetate (PVA) basic boom body is little side's body, and little side's body 10 is 1.0-1.6cm.
The invention has the advantages that: reduced floor space, cost reduces, long service life.Can effectively remove nitrogen, phosphorus in the sewage.
Fig. 1 is a system diagram of removing nitrogen, phosphorus in the sewage at present.
Fig. 2 removes nitrogen phosphorus and organic system diagram in the sewage for the present invention.
Fig. 3 removes nitrogen phosphorus and organic system diagram in the sewage for the present invention.
Fig. 4 is a material structure principle schematic of the present invention.
Below in conjunction with accompanying drawing in detail most preferred embodiment of the present invention is described in detail: it is by 55-65%, polyvinyl acetate (PVA) is the basic boom body, wearing into 80-100 order powder and the silicic acid 4-10% back that stirs with the natural cellulose of 30-40% enters bulking machine simultaneously with polyvinyl acetate (PVA) basic boom body and carries out expanded, make natural cellulose and silicic acid all penetrate into polyvinyl acetate (PVA) framework body inside, make cavernous little side's body 10.Hole 8 on little side's body 10 is 0.10-0.20mm (sponge shape hole), and polyvinyl acetate (PVA) basic boom body is little side's body, and little side's body 10 is 1.0-1.6cm.Example 1: a kind of poly vinyl acetate material, it is to be the basic boom body by 55% polyvinyl acetate (PVA), wearing into stir back and polyvinyl acetate (PVA) basic boom body of 80 order powder and silicic acid 4% with 30% natural cellulose enters bulking machine simultaneously and carries out expanded natural cellulose and the silicic acid of making and all penetrate into polyvinyl acetate (PVA) framework body inside, make little side's body 10 of porous 8 shapes, finished product.The working temperature of bulking machine is 135 ℃, and pressure is 4kg/cm
2, 30 minutes time.Little side's body 10 is 1.0cm, and the hole 8 on little side's body 10 is 0.10mm.Example 2: a kind of poly vinyl acetate material, it is to be the basic boom body by 60% polyvinyl acetate (PVA), wearing into 90 order powder and silicic acid 8% back that stirs with 35% natural cellulose enters bulking machine simultaneously with polyvinyl acetate (PVA) basic boom body and carries out expanded, make natural cellulose and silicic acid all penetrate into polyvinyl acetate (PVA) framework body inside, make little side's body 10 of porous 8 shapes, finished product.The working temperature of bulking machine is 150 ℃, and pressure is 6kg/cm
2, 25 minutes time.Little side's body 10 is 1.3cm, and the hole 8 on little side's body 10 is 0.15mm.Example 3: a kind of poly vinyl acetate material, it is to be the basic boom body by 65% polyvinyl acetate (PVA), wearing into stir back and polyvinyl acetate (PVA) basic boom body of 100 order powder and silicic acid 10% with 40% natural cellulose enters bulking machine simultaneously and carries out expanded natural cellulose and the silicic acid of making and all penetrate into polyvinyl acetate (PVA) framework body inside, make little side's body 10 of porous 8 shapes, finished product.The working temperature of bulking machine is 160 ℃, and pressure is 7kg/cm
2, the time is 20 minutes.Little side's body 10 is 1.6cm, and the hole on little side's body 10 is 0.20m.1, the present invention all adopts happiness water-based material, is not supply with under the special oxygen situation therefore, also can be at the multiple microbial bacteria of the inner generation of the present invention.2, because the present invention be a vesicular, therefore corresponding sewage contacts with microorganism that its surface-area is relative to be increased, acceleration biological processes process, and its surface-area is 3500m
2/ m
33, because surface-area has activated carbon, therefore can organism-absorbing learn the poisonous microorganism when handling, help removing the nitration reaction process.4, the life-span long, the present invention can reach 7 year working life through the corner angle wearing test.5, show that through test-results the adherent activated carbon does not come off in the test of long duration process, do not break away from attached to the multiple nitrifier in the present invention.6, (as Fig. 2,3) used in sewage disposal and porous polyurethane jointly.The result has reached the above water quality standard of stipulating among the quality standard of water environment GB3838-88 of the People's Republic of China (PRC) of four classes.7, compare with Sewage treatment systems commonly used, under the situation of same treatment ability, shared region reduces 30%, thereby investment is reduced greatly, and cost descends.8, under the bigger situation of Sewage treatment systems load variations, also can carry out work well, under load change, treatment effect is not affected.9, because the use of material of the present invention, the biological processes process needn't be ad hoc the oxygenation system, also simplified schedule of operation simultaneously.1-holds the pond, deposits sewage, 2-pump, 3-pneumatic pump, 4-boiling pool, 5-boiling pool, 6-settling tank, 7-pump, 8-hole, 9-porous polyurethane material, the little side's body of 10-, removes the organism in the sewage.The present invention is to sewage treatment process: sewage enters and holds in the pond 1 then that pump 2 is driven into sewage in the boiling pool 4, by porous polyurethane material organism is handled, absorb the Toxic that is unfavorable for nitration reaction by activated carbon simultaneously, enter into another boiling pool 5 by boiling pool 4 again, by the present invention nitrogen phosphorus is carried out nitration reaction, enter again in the settling tank 6 and enter precipitation, top is discharged, sedimentary mud is squeezed in the boiling pool 4 by pump 7 again, reaches country's discharging water quality standard so repeatedly.
