Description
Technical field
The present invention relates to the technical fields of industrial residue recycling and reusing, and in particular to a kind of industrial residue prepares siliceous fertilizer
Method realizes the harmless treatment of electrolytic manganese residues.
Background technique
Silicon is one of the chief elements in the earth's crust, in the soil mainly with a variety of shapes such as crystalline silicon, amorphous silicon and organosilicon
Formula exists.With the rapid development of modern agricultural technology, researcher has found that amorphous silicon and water-soluble silicon can be mentioned significantly in soil
The yield of high crops, moreover it is possible to improve the performances such as crops resistant to lodging, disease resistance, drought-resistant, and promote the decomposition of organic fertilizer, promote
Into nutrient effective use, the harmful substances such as ferrous and methane are mitigated or eliminated harm, make loosing soil and prevent heavy metal
Pollution and other effects.However the silicon in soil, mainly based on crystalline silicon, only effective silicon existing in soil is difficult to meet farming
The production requirement of object.China is large agricultural country, and through investigating, the Yangtze river basin has 70% soil to lack silicon, Liaodong Peninsula, Huang-Huai-Hai
Area's general soil lacks silicon, therefore exploitation prepares siliceous fertilizer and is particularly important.
Currently, there are mainly two types of the methods of domestic production siliceous fertilizer.One kind be it is artificial synthesized, cost is relatively high；Another kind is adopted
It is process with industrial solid castoff, mainly includes high-speed rail metallurgical slag, phosphoric acid industry waste residue, flyash, gangue, silicon ash
Stone, cullet etc. realize the recycling of resource by suitable technique, are the developing direction of siliceous fertilizer preparation process.
Electrolytic manganese metal slag (hereinafter referred to as are as follows: manganese slag) is after manganese carbonate ore prepares manganese sulfate solution by sulfuric acid process leaching
Remaining acid waste residue, discharge amount is big, and according to statistics, every production 1t manganese metal will generate the manganese slag of 8-9t, and China is mostly electric
The method that Xie Meng enterprise is all made of stockpiling of building a dam does not only take up valuable land resource, and due to cinder field construction or rain drop erosion
The problem of, plurality of heavy metal, ammonia nitrogen can be flowed into surrounding body and soil therewith in slag, cause environmental pollution, be seriously endangered
Therefore periphery safety of human and livestock selects a kind of suitable method imperative using manganese slag.According to investigations, contain in manganese slag organic
Nutrient or substance including matter, ammonium sulfate, manganese, silicon, selenium, ammonia nitrogen, potassium, sodium, iron, boron etc., are necessary to crop production
Nutrient can increase the fertilizer efficiency of soil, promote the growth of crop.If certain processing can be passed through, siliceous fertilizer is made in manganese slag,
The effective recycling for being not only able to achieve manganese slag is utilized with comprehensive resource, and reduces the pollution to environment, generates good economic effect
Benefit, environmental benefit and social benefit.
Currently, having the method that fertilizer is made in electrolytic manganese residues by some document reports, these contents reported in the literature are plucked
It records as follows:
Chinese patent CN102372527A discloses a kind of preparation method of Si-Ca-Zn-S-Mg fertilizer, by industrial manganese slag weight
It is raw material than 55-65%, Iron Ore Powder 3-8%, boron mud 3-8%, ashes 18-22%, zeolite powder, rare-earth original ore, is acidified with sulfuric acid,
Obtain product A；Sulfuric acid acidic phosphorus mine powder obtains B；Humic acid, ammonium sulfate, water three are mixed into ammonification chelating, obtain C；By three kinds
Product and magnesium sulfate mixing are obtained than more comprehensively middle trace-element compound fertilizer.This method mainly uses wet processing, utilizes
A large amount of, middle amount and microelement are combined together, prepare Si-Ca-Zn-S-Mg fertilizer, effectively by manganese slag, ashes, rare-earth original ore etc.
Ground improves utilization rate of fertilizer, has saved the energy, but not silicon in activation electrolytic manganese slag.
Jiang Minglei et al. carried out electrolytic manganese metal slag prepare silicomanganese fertilizer experimental study (nation manganese industry, 2014,32 (2):
16-19), the auxiliary agents, in mass ratio 1.00:0.60:0.15 such as calcium carbonate, sodium carbonate, sodium hydroxide are added in electrolytic manganese residues:
0.10, through high-temperature calcination, the available silicon content of acquisition reaches 6.94%, and obtains available silicon content with Microwave Digestion and reach
8.08%, while water-soluble manganese content, up to 1.51%, solubility in citric acid manganese content meets silicomanganese fertilizer standard up to 5.01%.The technology is adopted
With high-temperature calcination technique and Microwave Digestion refined manganese dioxide slag, silicomanganese fertilizer is prepared, silicon obtains in manganese slag activates to a certain extent, but not
Reach siliceous fertilizer standard.
Zhu Yahong has been carried out electrolytic manganese residues manure resources research on utilization (professional degree, Ningxia University paper, 2015), opinion
Text has investigated electrolytic manganese residues and electrolytic manganese residues and organic-inorganic compound mixed fertilizer to soil physico-chemical property and agricultural product security respectively
It influences.The result shows that application electrolytic manganese residues are better than inorganic fertilizer efficiency is administered alone；It is beautiful after electrolytic manganese residues and organic fertilizer compounding application
Rice dry-matter accumulation amount dramatically increases；After electrolytic manganese residues-inorganic composite mixed fertilizer application, capsicum Vc and solvable sugared content significantly increase
Add；And after electrolytic manganese residues and organic-inorganic compound mixed fertilizer application, promote plant growth and development, foods met food security standard is
The new-type fertilizer resource that can be developed and used.The research using crops are directly applied electrolytic manganese residues and and electrolytic manganese residues with have
Machine-inorganic composite mixed fertilizer method explores the fertilizer efficiency of electrolytic manganese residues, but untreated manganese slag cannot achieve resource and maximize benefit
With.
Wang Jing, agriculture Gui Yin, Du Dongyun et al. have carried out research (the comprehensive benefit of mineral products that manganese leached mud prepares white carbon black and manganese fertilizer
With .2012,6:57-59), paper extracts white carbon black using industrial manganese leached mud as raw material, and water-soluble manganese content is in waste residue
1.6%, solubility in citric acid manganese content is 5.1%, reaches the requirement of manganese fertilizer, and adding HyPerF10 is anticaking agent, is reached in additional amount
To after 0.07%, the anti-caking time gradually extends.Silicon extraction in manganese slag is mainly prepared into white carbon black, manganese reaches manganese fertilizer in waste residue
It is required that but leached using high-concentration sodium hydroxide solution, corrosive equipment, and produce a large amount of lye and need to handle.
In conclusion the technique that existing literature is reported, generally just for water-soluble and solubility in citric acid element straight in manganese slag
Utilization, especially promoter manganese are connect, and resource utilization is not realized to existing silicon a large amount of in slag.And China's soil there is a serious shortage of
Active silicon resource, if the demand agriculturally to siliceous fertilizer can not only be alleviated, and be able to achieve to manganese slag using the silicon resource in manganese slag
Efficient utilization.Therefore, it selects the silicon in a kind of suitable method activation electrolytic manganese slag to prepare siliceous fertilizer to have great importance.
