Abstract
The invention discloses a preparation method for a high-strength pin needle type three-dimensional filler, which uses polypropylene (PP) strands with a diameter of 0.4-0.5mm as main materials. The preparation method comprises the following steps: (I) digesting for 7-9 hours in steam of 130 DEG C; (II) fishing out and putting the PP strands in the environment of (-) 8 DEG C to freeze for 50-70 minutes; (III) putting the frozen PP strands in additive-containing stream of 130 DEG C for digesting for 14-16 hours, and thus conducting a chemical reaction on the surfaces of the strands to form a permanent antioxidant layer. The filler product prepared by the preparation method has a large specific area, high oxygen transfer efficiency, quick microorganism metabolism and large variable porosity, is easy to scour and de-mould, is not sticky, clustered and blocked, and helpful for degrading organic sludge and improving advanced technical indexes for refluxing; moreover, the filler product has the unique performances of corrosion resistance, aging resistance and long service life. The high-strength pin needle type three-dimensional filler prepared by the preparation method has the advantagesthat the service life is 2-3 times that of a common elastic three-dimensional filler, 3-4 times that of a hard filler and a combined filler, and the service life is at least more than 10 years.
Description
Technical field
The present invention relates to the water treating equipment field, especially a kind of preparation method of high strength pine needle formula 3-D filler.
Background technology
In the biochemical processing of sewage, filler is to improve the vital part of biochemical treatment efficient, and it is the carrier of biological bacteria growth and breeding, is undertaking and evenly cutting underwater bubble, raising oxygen in water efficient, bio-film colonization, washing away multiple functions such as demoulding.The quality of carrier performance is the key factor that influences wastewater treatment efficiency and economic benefit.
At present, the most frequently used suspension type filler of sewage disposal has: 1. hard filler 2. semi soft packing 3. soft-filler--combined stuffing is elastic solid filler 4..Wherein, elastic solid filler be the 4th generation new packing, the key technical indexes is better than other various fillers.But above-mentioned four kinds of fillers have a common shortcoming, only will change about 3 years work-ing life, its major cause is: filler adopts plastic material, and the oxidative degradation of light of being heated in the life-time service process, the factors such as impact of mechanical external force cause that filler appearance and internal performance are aging, intensity reduces, be difficult to bear biomembranous loading, cause filler to come off, the glutinous group that links, reduce the metabolism of microorganism, progressively lose biochemical effect.Just frequently change filler in nearly about 3 years, and increased running cost and the overlapping investment of sewage disposal, seriously restrict the development of water treatment business.
Summary of the invention
Shortcomings such as the applicant is poor at filling intensity in the biochemical treatment of above-mentioned existing sewage, the life-span is short provide a kind of preparation method of high strength pine needle formula 3-D filler, thereby increase the intensity of filler, improve its durability degree.
The technical solution adopted in the present invention is as follows:
A kind of preparation method of high strength pine needle formula 3-D filler, polypropylene PP strand with 0.4～0.5mm diameter is main raw, (I) boiling 7～9 hours in 130 ℃ of steam, (II) pull and be placed in-8 ℃ of environment freezing 50～70 minutes out, (III) be placed in 130 ℃ of steam that contain additive boiling again 14～16 hours, make the strand surface that chemical reaction take place and form permanent anti oxidation layer.
The described III additive in the step comprises that concentration value is that 5% UV light absorber UX-326, concentration value are that 5% Tyox B and concentration value are 3% methyl alcohol.
Cooking time was preferably 8 hours during described I went on foot.
The freezing time was preferably 1 hour during described II went on foot.
Cooking time was preferably 15 hours during described III went on foot.
Beneficial effect of the present invention is as follows:
The high strength pine needle formula 3-D filler product of manufacturing of the present invention has not only that specific area is big, oxygen transfer efficiency is high, microorganism metabolism is fast, variable voidage is big, it is easy to wash away demoulding, do not stick company, not conglomeration, do not stop up, the modern technique index that is conducive to degraded and the backflow of organic sludge has more special performance corrosion-resistant, anti-aging, long service life.Through experiment test and comparison repeatedly, be 2～3 times of ordinary elasticity 3-D filler work-ing life of the present invention, is hard filler and combined stuffing 3～4 times, work-ing life minimum reaching more than 10 years.Efficient low-consume of the present invention, low-carbon (LC), practicality have wide market outlook, will play an important role for China's water treatment business development.
Embodiment
It is main raw that the present invention adopts high-quality polypropylene (PP), is equipped with additives such as hydrophilic, absorption, antioxygen, makes the elasticity strand with burr through drawing process, and arranges to be fixed on the axial cord with the spiral radiation form and form.Strand typically have a diameter from 0.4～0.5mm.The making step of polypropylene strand is routine techniques, also can directly buy the polypropylene strand.
The elasticity strand is lashed in 130 ℃ of steam boiling 7～9 hours, be preferably 8 hours; Pull and be placed in-8 ℃ of refrigerator-freezers freezing 50～70 minutes then out, be preferably 1 hour; Be placed in 130 ℃ of steam boiling again 14～16 hours, and be preferably 15 hours.Before and after altogether boiling, freezing, boiling 24 hours, impel material molecules to meet again and arrange, strengthen the tough elasticity of steel of strand, improve the anti-folding of strand, tension, ultimate compression strength and resistance to deterioration.
Freezing through-8 ℃, when strand is put into 130 ℃ of high temperature boiling water boilings, adding UV light absorber UX-326(concentration value in water is 5%), Tyox B (concentration value is 5%), methyl alcohol additives such as (concentration value are 3%), boiling 15 hours, make the strand surface that chemical reaction take place, form permanent antioxygen layer, thereby suppress to delay strand in processing and manufacturing, in application and the storage process, because of mechanical stress, caused by factors performance degradations such as optical radiation are heated, the performance of guaranteeing strand has permanent intensity and loading capacity, prolongs the work-ing life of filler.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion is referring to claim to the restriction of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
