Abstract
The invention discloses a uranium ore wastewater plasma co-processing method and a uranium ore wastewater plasma co-processing system, which comprise a wastewater storage tank, an acid removal device, a heavy metal treatment device, a plasma melting device, a waste gas treatment device and a glass recovery device, wherein the wastewater storage tank is used for carrying out pre-treatment on wastewater to be treated, and the acid removal device is connected with the wastewater storage tank and is used for neutralizing acidic substances in the pre-treated wastewater in the wastewater storage tank. The volume reduction effect of the tailings in the wastewater treatment process is remarkable, the plasma technology is adopted, the energy density is high, the working temperature can be operated at 1000-1500 ℃, the volume of the tailings after melting treatment is reduced by more than 70%, the vitreous slag formed by melting the tailings is good in compactness and free of gaps, heavy metals and various harmful elements are coated in a Si-O crystal structure, and tests on the migration characteristic and the leaching characteristic of the vitreous road slag show that the leaching concentration of all elements is far lower than the specified standard level.
Description
Technical field
The present invention relates to waste process field, specially a kind of uranium ore waste water plasma body cooperative method of disposal and system.
Background technique
Wastewater source is mainly two parts in Uranium Industry: the mining wastewater and Uranium extraction process generated in recovery process
The waste water of middle generation.Wherein mining wastewater include the outer draining of mine or excavating plant, accumulation on ground surface ettle dipping water；
Uranium ore processing waste water includes leachate etc. after adsorption tail liquid, saturated resin regeneration tail washings and precipitating after ion exchange.Uranium ore
The waste water generated during picking up not only contains the radioactive elements such as U, Th, Ra, Po, Pb, also generates various heavy metal wastewater therebies, such as
Fruit is dealt with improperly, will cause the heavy metals exceeding standards such as Pb, U, Cu, Zn, Ni, Cd, As, Co of surface water and groundwater, makes to environment
It is destroyed at serious.In addition, the untreated qualified outlet of the strong acid or highly basic that use in uranium ore process will destroy the water quality of water body,
It will lead to water body and soil acidification when serious, directly affect the existence of animals and plants.
The processing method of uranium ore waste water mainly have physisorphtion, membrane processing method, biological treatment, chemical precipitation method,
Ion-exchange etc..Physisorphtion using porous adsorbent for example active carbon handle radioactive wastewater, can binding molecule,
Ion, and the effect to the selective absorption of different types of nucleic, but adsorbent is expensive, regenerates costly；Membrane technology
It is good with effluent quality, the features such as low energy consumption, stable and reliable operation, but phenomena such as there are films by embolism, contaminated, fracture of wire, it must
It must often clean；Requirement of the culture of specified microorganisms to environmental condition is very harsh in bioanalysis, and exists and take up a large area, manage
The disadvantages of reason is complicated, wastewater to reach standard difficulty is big；The few Spent Radioactive water process of the ion-exchange amount of being only applicable to, and can generate
Largely there is radioactive spent resin.Chemical precipitation method is to be co-precipitated it with nucleic by precipitating reagent and be transferred to small size
It precipitates in bed mud, the method simple process, operating cost are low, but body refuse yield is more.
The tailings amount that above-mentioned each processing method generates is larger, and in tailings containing a large amount of Pb, U, Cu, Zn, Ni, Cd, As,
The heavy metals such as Co.Currently, these tailings are generally handled by being deposited in the modes such as tailings library or backfilling goaf, be easy by
To washing away for rainwater and underground water, leads to loss by dissolution, cause serious environmental pollution.At home and abroad, draw because mine dam damages
After the slag loss event of hair occasionally has generation, tailings to enter water body, since the redissolution of heavy metal leads to the radioactive water in water
It is flat to increase, pollute nearby soil and surface water body.The Tailings Dam percolating water of south China somewhere uranium mill once to neighbouring fish pond,
Well water pollutes.Accordingly, it is desirable to provide a kind of tailings that can will be generated in uranium ore wastewater treatment carries out the processing of thorough inerting
Radioactive element and other heavy metals are thoroughly solidified while reducing tailings amount, meet protection against erosion, resistant to corrosion and leaching by scheme
Requirement out.Therefore we make improvement to this, propose a kind of uranium ore waste water plasma body cooperative method of disposal and system.
Summary of the invention

10~11, the waste liquid in deacidification device (2) in milk of lime and after flocculation enters a plate and frame filter press (6) and is dehydrated, and realizes
Grain slag separation, reduce post precipitation, removing heavy metals, acidification and secondary plate and frame filter press (7) processing load, a plate compression
The tailings and waste water that machine (6) sub-argument goes out respectively enter plasma fusion device (4) and sedimentation basin (8), and sedimentation basin (8) is used for will
Suspended matter in the water outlet of plate and frame filter press (6) further settles, and realizes precipitating completely, the tailings of sedimentation basin (8) send to etc.
Gas ions melting plant (4)；
The S3 step includes being added the waste water from deacidification device (2) except metal agent is handled, so that a huge sum of money therein
Category forms solid slag, and heavy metal processing unit (3) is specially to remove radium acidification pool, described except radium agent is CaCl2Content is 20g/m3
CaCl2Solution, except the radium reaction time is 10min, the solution after removing heavy metal need to be added sulfuric acid and waste water is neutralized to permission
In the range of discharge standard pH=7~9, sedimentation time 12h, secondary plate and frame filter press (7) be used for the tailings of sedimentation basin (8) into
Row dehydration, dewatered liquid enter slot type letdown tank (9) and drain into neighbouring water body, and tailings then enters plasma fusion
Device (4) carries out melt process；
The S4 step include the solid slag from heavy metal processing unit (3) plasma fusion device (4) it is equal from
It is melted completely under the action of daughter beam, plasma fusion device (4) uses the direct current untransferable arc plasma of 20kW~50kW
Torch, the plasma torch thermal efficiency be greater than 70%, electrode life be greater than 400hr, wherein the operating temperature of gas ions furnace be 1000 DEG C-
1500 DEG C, gas residence time is greater than 2s；
The S5 step includes that the tail gas being discharged from plasma fusion device (4) is passed through cooling, purification, Sour gas disposal
It is carried out separation and recycling with particulate separation treatment process, emission-control equipment (10) is responsible for cool down by exhaust gas, cooling
Glass dregs recycling is carried out by glass recyclable device (11) afterwards.
