Description
Technical field
The present invention relates to the processing methods of the processing method of the dangerous waste containing arsenic, more particularly to the slugging containing pozzuolite.
Background technique
Arsenic and its compound have extensive toxic action to people and other organic life entities；For plant, the poison of arsenic
Evil effect shows the moisture conveying for inhibiting plant, destroys the generally acknowledged teratogenesis of leaf, the carcinogenic and mutagenesis factor.In the smelting of arsenic
During the production and application of refining and its compound, a large amount of arsenide is introduced into environment, and polluted source is detrimental to health, because
This people has given very big concern to arsenic poison harm.China's " industry hygiene standard " regulation: arsenic highest permits in the surface water
Perhaps mass concentration is 0.04 mg/L, and the per day highest permission mass concentration of arsenide (based on arsenic) is in the atmosphere of residential block
0.003mg/m3.Industrial " three Waste " discharges tentative standard regulation: arsenic and its inorganic compound highest allow mass concentration to be 0.5
mg/L.Using modern wastewater processing technology, arsenic-containing waste water can be easier to realize qualified discharge, however, smelting process generation is consolidated
Sediment containing arsenic that body arsenic-containing waste and processing waste water, spent acid generate etc. is thorough there is presently no obtaining to the pollution and harm of environment
Bottom radical cure, a large amount of valuable metals are not fully used, and the requirement of the discharge status of arsenic-containing waste and environmental protection administration is still apart
It is very remote.Arsenic-containing waste mostly uses greatly the method processing for hoarding storage for a long time, as high concentration arsenic-containing waste is cumulative, is
It prevents secondary pollution, urgent problem to be solved is become to its harmless treatment.Processing arsenic-containing waste residue and dirt both at home and abroad at present
The common solidification technology of mud is cement solidification, organic polymer solidification, bitumen solidification and pyrogenic process solidification.These processing modes
Not only increase business burden, but also causes the significant wastage of resource.In the production processes such as metallurgical industry, chemical industry, solution
Dearsenification is handled frequently with sulphide precipitation, to generate the high arsenic sulfide slag of arsenic content.Arsenide be both extremely toxic substance and
Indispensable resource in the national economic development.Therefore, needs and the state of environmental protection are not only made from arsenic-containing waste residue recycling arsenic
The needs of people's sustainable economic development.Currently, being mainly the following processing technique: 1, arsenic sulfide slag produces arsenic trioxide
Processing technique is divided into two major classes, i.e. pyrogenic process and wet process according to its technical characterstic.Pyrogenic process is that the current country recycles three from arsenic sulfide slag
Aoxidize the method that two arsenic most generally use.This technology maturation, process is short, at low cost；But its three oxidation for handling drying regime
Two arsenic, it is difficult to ensure good operating environment, easily cause the secondary pollution of environment, and product purity is low, the arsenic rate of recovery is low.It is wet
Method handle arsenic sulfide slag, i.e., using acidleach, alkali leaching or salt leaching etc. handled, first arsenic is separated from slag, then again into
One step recycles arsenic product or carries out harmless treatment.This technology does not generate dust, is able to satisfy environmental requirement, have low energy consumption,
It pollutes the advantages that small, high-efficient, but its process is complex, processing cost is high.
Chinese invention patent notification number CN102151690B discloses a kind of method for handling arsenic sulfide slag, toward arsenic sulfide slag
Middle addition inorganic flocculating agent liquid, stirs evenly；Solid powder adsorbent is added, is stirred evenly；It is eventually adding asbestos wool stirring.
Although this method can reduce the Leaching of the dangerous wastes containing arsenic such as arsenic sulfide slag, dangerous waste that treated can be directly entered danger
Landfills reduce the harm to environment, but the valuable metal in arsenic sulfide slag is not recycled, and is caused
The waste of resource；For another example Chinese invention patent publication number CN106834736A discloses the separation work of copper and arsenic in arsenic sulfide slag
Skill, vulcanized slag leach to obtain copper concentrate (copper sulfide) and alkaline leaching liquid by Sodium Hydroxide Alkaline.Contain arsenic in leachate, adds
Enter waste acid and carry out heavy arsenic, obtains arsenones precipitating and metabisulfite solution, but it uses wet-treating, it is complex that there are processes,
The high problem of processing cost.
Summary of the invention
The technical problem to be solved by the present invention is to existing arsenic sulfide slag pyrogenic process, wet-treating, there are many drawbacks, or
Solid powder adsorbent is added using inorganic flocculating agent liquid is added into arsenic sulfide slag, valuable metal can not be recycled, mentioned thus
It not will cause secondary pollution for one kind and process be simple, at low cost, the nuisanceless place of the slugging containing pozzuolite of valuable metal can be recycled
Reason method.
The technical scheme is that provide a kind of new non-pollution processing method of slugging containing pozzuolite, it include with
Lower step: (1), the preparation of the ball of slugging containing pozzuolite: slugging containing pozzuolite, water and bentonite are by (180-220): (50-60): (5-15's)
Weight ratio stirs evenly, and the bead of diameter 6mm-10mm is made；(2), pelletizing covering: bead after drying, is wrapped up in its appearance
One layer of curing agent white lime, white lime and the ball weight of slugging containing pozzuolite ratio are (6-7): 1；(3), coating ball roasting: 710 DEG C-
Under the conditions of 730 DEG C, roast 4h-6h, oxidative decomposition occurs under aerobic conditions for slugging containing pozzuolite, generate SO2 gas and
As2O3 gas, SO2 gas and As2O3 gas are reacted with the white lime of coating ectosphere produces calcium sulfate and calcium arsenate respectively；
(4), removing coating from coated spheres: grinding coating ball, and coatings and kernel separate；(5), coatings fill: by the coating of removing
Under layer landfill；(6), kernel is ground, metallic copper, phase analysis heap together with coatings is recycled by acidleach, iron replacement
Deposit landfill.
Arsenic solidification detection is carried out to the coatings of step (4) in above scheme, by coatings respectively pH value be 12.3,
7.0 and 1.0 3 kind under the conditions of leach 72h, leaching liquid-solid ratio is 10:1, leaching rate < 1%.
Pozzuolite slugging, water and bentonitic weight ratio are 200:55:10 in step described in above scheme (1), small
Bulb diameter is 8mm.
White lime and the ball weight of slugging containing pozzuolite ratio are 6.5:1 in step described in above scheme (2).
In step described in above scheme (3) under the conditions of 725 DEG C, 5h is roasted.
It is the oxides such as silicate the beneficial effects of the invention are as follows kernel after coating ball roasting；Outer layer coating layer is sulfate
And arsenate.It is polished to be coated ball, since internal layer is different with outer layer hardness, internal layer and outer layer are easier to separate, in coatings
Arsenic mineral preferably fixed, copper leaching rate is 65-70% or so, and copper has obtained effective recycling.
