Description
Technical field
The invention belongs to environmental protection, field of fertilizer production, more particularly to zinc gray cadmia synchronous production organic zinc iron fertilizer side
Method and application.
Background technology
Hot dip galvanizing process, it is a kind of simple process of Treatment of Metal Surface in hardware products production.The technique is tried out in making
The complicated Treatment of Metal Surface of type, and require artistic face handle in simple production and use (Li Rongsheng, 1994；Ma Dong
Kui, 1992；Barakat M.A., 2003.).But the spelter heat fusing in hot dip galvanizing process flashes to gas, run into cold above
The surface of solids, be set in the surface of solids just as vapor and produce a certain amount of zinc gray.The Main Ingredients and Appearance of zinc gray is secondary
Zinc oxide, its zinc oxide content account for 75%, and about 5% zinc, also trace iron, nickel etc., will be to rings if managing improperly or dumping
Certain pollution is caused in border, damages health, especially very thin zinc gray particulate to human health damage very it is big (Cai etc.,
2015).For environmental protection and zinc gray can be comprehensively utilized, create economy and environmental benefit, this is that galvanizing producer closes jointly
The problem of heart (Ma Dongkui, 1994；Dvorak P.＆ J.Jandova, 2005；Li De is superfine, and 2010；Verbinnen etc.,
2016).As the improvement of people's living standards, reinforcement of the people for environmental consciousness, the national implementation for law enforcement for environmental protection is right
It is very strict in the requirement of galvanizing factory zinc gray fixed-end forces.
In hot galvanizing process, the cell body iron and workpiece of plating piece and zinc groove remain in plating piece surface after pickling and not yet floated
Wash most molysite and act on the zinc-iron alloy to be formed with zinc liquid, because the alloy melting point is high, than great and heavy and zinc liquid bottom, it is necessary to
Periodically pull out, otherwise can influence the quality of galvanizing production, this part zinc-iron alloy pulled out be exactly cadmia (Chen Jin, 2007；What
Small wind etc., 2008).
Zinc gray is mainly zinc bath surface and atmosphere is oxidized and some fluxing agents enter coating bath and made with liquid Zn
With and formed, be made up of ZnO, metallic zinc and chloride, the mass fraction of general zinc is between 50% one 80%.In galvanizing
During, for the direct utilization rate of zinc typically in 60% or so (malleable iron body only 40%), remaining then forms cadmia and zinc gray, general zinc
Slag accounts for 20% or so, zinc gray account for 20% or so (Chen Jin, 2007；He little Feng etc., 2008).
More than the 30%--40% of the annual zinc total amount in the whole world is used for galvanizing.China is Chan Xin big countries, and yield occupies generation
Boundary is the first, counts within 2007 according to statistics, the zinc yield of 2005 is about 2,740,000 t.If China is 30% for the zinc amount of hot dip,
As more than 80 ten thousand t, zinc slag content are the 12.5% of zinc consumption, then the year quantum of output of hot galvanizing residue is higher than more than 10 ten thousand t.Due to zinc-plated
The fast development of industry, caused cadmia, zinc gray amount are also increasing.Therefore the research to zinc slag, the recycling of zinc gray is
Be highly desirable (Chen Jin, 2007；He little Feng etc., 2008).
Processing cadmia, the handling process of zinc gray is many at present, as liquate smelting process, the way of distillation, vacuum distillation method, aluminium method,
Produce chemical products etc., each of which have its own advantage and disadvantage (Chen Jin, 2007；He little Feng etc., 2008).These methods respectively have
Advantage and disadvantage, on water pollution control is mostly used for, the remediation contaminated soil for large area is also few, because cost is too high, has
Secondary pollution, at the same it is clear not thorough.
Nineteen twenty-six A.L.Sommer and C.B.Lipman have found that zinc is the essential nutrient element of plant growth, are plant structures
Component element (Cao is respectful and Liang Mingzao, 2003).Little leaf can be produced after the peach in orchard, pears, apple tree zinc-deficiency, meeting after corn zinc-deficiency
White seedling and floral leaf stripe disease are produced, in low-lying rice field, rubescent stiff seedling (being commonly called as wearing red red-tasselled official hat) often occurs in early rice, and symptom is similar
Potassium deficiency, it is exactly caused by zinc-deficiency, rape zinc-deficiency causes setting percentage to reduce (Xie Qianyuan and Zhu Qiaozhen, 1983).
Zn-ef ficiency participates in or influenceed the metabolism of body.Zinc be the constituent of many enzymes and its required of effect because
Son, more than 200 kinds of enzyme are relevant with zinc (o`Dell, 1984).And the metabolism of the material such as protein, amino acid, lipid, carbohydrate
Process is required to enzyme participation, thus zinc directly or indirectly participates in the metabolic process of above-mentioned substance.It is reported that during animal zinc-deficiency, permitted
Dissimilation strengthens in vivo for amino acids such as tryptophan, leucine, glycine, methionine and cystine etc., and excretion increases
(Hsu, 1968~1972)；During sheep zinc-deficiency, sulphur, elimination of nitrogen amount are significantly higher than control group in urine, cause internal nitrogen, sulphur to bear
Balance (Somers, 1969)；After animal zinc-deficiency 10 hours, thymidine core former times kinase activity declines, and archaeal dna polymerase, RNA gather
Synthase activity also weakens therewith；After 18 hours, DNA replication dna reduced capability；Occurs protein dyssynthesis after 48 hours, therewith
Cell division and growth retardation.During animal zinc-deficiency, insulin synthesis and secretion and glucose utilization be obstructed (Fores etc.,
1984) it is important to show that zinc has the function that in body substance metabolic process.The normal immunological function that maintenance machine is stopped.According to a variety of texts
Report is offered, zinc-deficiency animal causes immune organ such as thymus gland, lymph node, spleen etc. that atrophy occurs, and periphery lymphocyte is reduced, and T is thin
Born of the same parents' miopragia, so as to cause body immunity to reduce and supplementing zinc then enables its function recover normal.eBisel
(1680) think, the redistribution of zinc and adjustment in body, contribute to body to resist to infect when animal is infected, and liver increases to zinc intake
Add, its function can be made more preferable；Blood zinc content reduces and is more beneficial for phagocyte antibacterial action.Keep the stabilization of biomembrane.
Ehvapil (1973) proposes that zinc can suppress fatty peroxide or mercaptan oxidation, so as to keep biomembrane first.
In biosphere, the mankind are by " soil-plant-people " or " soil-plant-animal-people " this two food chains
To obtain nutrition, for zinc also along this two food chain transmission, people is the highest consumer of this system.In November, 2008 exists
In the first " middle micro-element nutrition whole nation coorporative network " meeting that Beijing is held, brainstrust is from plant nutrient angle, again
Appealing will strengthen Meso- and micro-nutrients research, develop eutrophy plant by biological reinforced means to meet the need of health
Ask.National Science Research Council referrer needed zinc 15mg daily at 11 years old to growing up, the meals that Chinese NNFA is recommended
The quantity delivered of zinc is also 15g/d in food.According to the diet structure of Chinese residents, the zinc of adult's intake in 10mg/d or so,
If that is cereal crops seed zinc content is brought up to original 2~3 times, it is ensured that intake reaches 15mg/d.
China's wheat, some soil types such as loessal soil, soil, yellow moist soil, cinnamon soil, brown earth etc. and one of rice major production areas
A little calcareous Paddy Soils, neutral rice soil, Swampy Areas rice soil, Coastal saline land region rice soil belong to zinc-deficiency category.In general,
Zinc in soil can be divided into 5 kinds of forms, i.e. exchange state, carbonate combine state, organically combine state, oxidation state and mineral sequestration
State, plant can absorb for exchange state zinc.Can mutually it be converted between 5 kinds of forms of zinc, i.e., effective zinc (exchange state)
→ ※ slows zinc (carbonate combine state, organically combine state, oxidation state) → invalid zinc (mineral sequestration state), the direction of conversion and journey
Degree depends on soil physico-chemical property, mainly organic matter and pH value.
Zhang Huaiyu etc. have studied absorbing for zinc in corn-barley Rotation System using 65Zn, the results showed that inorganic states
After zinc applies normal soil and zinc deficient soil, corn only has 20.4% and 27.4% to this season utilization rate of zinc, there is 88.84%
Zinc residues in soil, 8.77% zinc leaching loss, and only 0.14% zinc is utilized by second stubble crop.Foliage dressing can also significantly improve
Zinc fertilizer utilization rate.The research report that China applies zinc to blade face focuses mostly in terms of fertilizer efficiency, and zinc is applied to zinc in crop body in relevant blade face
The research of content and its distribution accumulation is seldom.Wang Yanan etc. report apple rudiment before, spend rear 3d, foliage-spray sulfuric acid before fallen leaves
Zinc has different influences to root, stem, leaf Zn content.And introduced according to VolkerRoheld and IsmailCaKmak (2008), it is external
The method of application of trace element is mainly root outer spraying, and nutrient, through cuticula, is entered by blade face, blade back
Plant transmission tissue (xylem, forming layer, bast), and then the distribution to each organ has carried out detailed research.There is result
It has been shown that, applying zinc by blade face can make cereal zinc content improve 3 times.
In recent years, a few thing had done in terms of selenium-rich, zinc-rich and Fu Tie rice and wheat in China, and some is in life
Applied fairly largely in production.Research of the China to zinc-rich food lags behind exploitation, particularly to cereal crops.China resident from
The zinc taken in meals about 60% comes from grain, and only 40% comes from other food such as veterinary antibiotics, meat.Therefore,
For improving human body zinc nutrition, it is more easy and effective to improve rice, wheat edible position Zn content, it may have widely real
Border meaning.But current research of the China to zinc-rich food is relatively scattered, at many aspects such as edible mushroom, yeast, algae, tealeaves, vegetable
Dish, dairy produce etc. all have been reported that, their end product be exactly plant in itself, the zinc absorbed from soil or nutrition material is not necessary to
To be enriched with layer by layer.And rice is just different, need pass through the stages such as soil, crop root, cauline leaf, seed, brown rice, polished rice.By
Participate in influenceing the substance metabolism processes such as carbohydrate, lipid, protein and nucleic acid in zinc, performance and dimension to promoting breeding performonce fo animals
Hold animal health have good action (Liu Xuejian, 1995；Wang Zhiwu etc., 2005).From 1974, food and nutrition meeting were advised
The day for having determined zinc recommends dosage (RDA) to be not less than 15 milligrams daily.In addition to zinc is strengthened in food, the biology profit of zinc in food
With rate and essential trophic factor.This problem has been recognized in the World Health Organization (WHO) meeting, it is proposed that according to each
The estimation bioavailability of regional food mineral, adjust the intake (Li Daorong and Duan Suhua, 1997) of zinc.
Application of zinc fertilizer has been one of normal measure of agricultural production.To develop a circular economy, energy-saving and emission-reduction, protecting ecology
Environment, galvanizing factory zinc gray comprehensive utilization production zinc fertilizer can be solved industrial production environment pollution problem, and can solves agricultural
Zinc fertilizer resource problem is produced, promotes plant growth, eubolism in animal body is maintained, has in guarantee human body food enough
Zn-ef ficiency, have important practical significance and be widely applied value.
Although there has been fragmentary research report early stage, zinc gray plus sulfuric acid treatment are produced zinc sulfate to be applied as zinc fertilizer,
It is that method power consumption is high, has secondary pollution, does not have to substantially now.New technical thought and technical matters are used in the application, by zinc
Ash recycles production organic zinc fertilizer, Chelating state zinc fertilizer, liquid zinc fertilizer, can be greatly enhanced zinc fertilizer utilization rate, biological utilisation
Rate improves several times than common heart, and production process cost is low, and secondary pollution is few, only few waste liquid and waste gas discharge, meets
National industry development policies.
