Abstract
The invention relates to a method for treating solid mining and metallurgical waste by using photosynthetic bamboo, which belongs to the field of environmental pollution treatment. The method is characterized in that mineral separation tailings or/and mining waste rock or/and metallurgical waste residue are piled to form a triangular inner core (1), two edges of the triangular inner core (1) are flattened to form terraces (2), photosynthetic bamboo (4) are planted in the terraces (2), the terraces (2) are immobilized by roots (3) of the photosynthetic bamboo, the triangular inner core (1) is immobilized by the terraces (2), so all the solid mining and metallurgical waste is immobilized. After harvesting, the photosynthetic bamboo is used for preparation of charcoal, and the prepared biomass charcoal is used for metal smelting. The method provided by the invention overcomes the defect of environmental pollution caused by incomprehensive and incomplete disposal of solid mining and metallurgical waste in the prior art and has the advantages of easiness, practicability, high efficiency, economic performance, low cost and high benefits.
Description
Affiliated technical field
The present invention relates to field of environmental pollution control, be specially a kind of method of photosynthetic bamboo disposal mining and metallurgy solid waste.
Background technology
Existing metal selecting and purchasing is all by the barren rock of the mine tailing of ore dressing, mining and metallurgical slag air storage, mining and metallurgy solid waste is not carried out to complete disposal comprehensively, its air storage of leaving, metal wherein passes through wind, Exposure to Sunlight, drenching with rain is transformed into solubility salt polluted-water gradually, waste water enters after rivers directly pollution algae, fish, form biological chain and pollute.Not only contaminated environment, also wastes land resource, also especially easily causes geological disaster, and it is the difficult problem in China and the world that the ecology of mining and metallurgy solid waste is disposed.
Summary of the invention
The object of the invention is not carry out complete disposal comprehensively in order to overcome existing mining and metallurgy solid waste, cause the defect of environmental pollution, provide a kind of simple, high-efficiency and economic, cost is low, and the photosynthetic bamboo that income is high is disposed the method for mining and metallurgy solid waste.
The object of the invention is to be achieved through the following technical solutions:
Photosynthetic bamboo of the present invention is disposed the method for mining and metallurgy solid waste, it is characterized in that the mine tailing of ore dressing or/and the barren rock of digging up mine or/and metallurgical slag is piled into triangular core (1), the smooth one-tenth terraced fields in both sides (2) of triangular core (1), in terraced fields (2) the photosynthetic bamboos of upper plantation (4).
In such scheme, the mine tailing of described ore dressing or/and mining barren rock or/and metallurgical slag is piled into triangular core (1) in booth.
In such scheme, described metallurgical slag is made haydite, and haydite is used for planting photosynthetic bamboo.
In such scheme, the operation that described metallurgical slag is made haydite is: the metallurgical slag of molten condition is entered to the front molten bath of rotary kiln, high pressure air blast and spray into coal dust burning, stir under, the haydite that splashes out enters into rotary kiln, under the slowly running of kiln body, progressively cooling forming obtains haydite, and the flue gas of generation discharges after reclaiming flue dust.
In such scheme, after described photosynthetic bamboo harvesting, for charcoal processing, the biomass carbon obtaining is for metal smelt.
Photosynthetic bamboo is that inventor researches and develops for many years, is cultivated and is formed by fishscale bamboo and hybrid giant napier induce variation.Be the upright bunch type four-carbon plant of perennial grass family, have stronger photosynthesis, well developed root system, cane is solid, and plant is tall and big especially, and cold-resistant, drought-enduring, waterlogging ability is stronger.Due to mining and metallurgy solid waste containing heavy metal containing organic particularity, do not have at present plant well in mining and metallurgy solid waste, to survive, and photosynthetic bamboo do not need too many management just can be in mining and metallurgy solid waste growth and breeding.
The present invention adopts triangular core to pile up the scheme that adds the photosynthetic bamboo of terrace cropping, by the fixing terraced fields of root system of photosynthetic bamboo, and by terraced fields fixed triangle shape inner core, thus fixing whole mining and metallurgy solid waste.The heavy metal of the root system of photosynthetic bamboo in can complexing mining and metallurgy solid waste, can purify mining and metallurgy waste water, and the cauline leaf of photosynthetic bamboo can purify the air in mining area.Plant photosynthetic bamboo and only need little field management, and output is huge, can receive 30 tons of above cauline leafs, can gather in for many years for annual every mu.In the time being placed in booth, harvesting number of times becomes 4 months once from once a year, and output is turned over three times.The photosynthetic culm leaf of harvesting can be used for charcoal processing, biodiesel processed, papermaking, preparing fuel ethanol, and income is abundant.Therefore, the present invention, with cheap cost, is turned waste into wealth, and has not only effectively administered the environmental pollution that mining and metallurgy solid waste causes, and can also obtain very high income.
To sum up, the present invention has overcome existing mining and metallurgy solid waste and has not carried out complete disposal comprehensively, causes the defect of environmental pollution, and the method for the photosynthetic bamboo disposal mining and metallurgy solid waste providing is simple, high-efficiency and economic, and cost is low, and income is high.
