After answering one end time, the precipitation of uranium is accumulative too much, the space of blocking filter course 2, and flush pipe 11 will work the precipitation of uranium
Thing develops.During owing to rinsing, the uranium content in aqueous solution is higher.Therefore, when recoil is carried out, at the end of device
Collect rinse solution at water outlet, uranium is processed and recycles.
The material of filter course 2 is that nano zero valence iron combines SRB (sulfate reducting bacteria), and filter course 2 is anaerobic biofilter
Main body, its effect is to provide the surface of attached growth of microorganisms and the space of suspension growth.Nano zero valence iron is as mainly filling out
Material is essentially identical with biofilter or contact-oxidation pool filler, and i.e. specific surface area is relatively big and rough surface, shape and porosity close
Structural load suitable, that mechanical strength is high and biologically inert is good, lighter weight makes anaerobic biofilter is little.SRB (sulfate
Reducing bacteria) it is the composite flora comprising multiple sulfate reducting bacteria, hexavalent uranium can be reduced directly, it is also possible to by sulfur
Acid ion is reduced into S2-, generate sulfide precipitation with uranium.During Zero-valent Iron reduction hexavalent uranium, oxidized generation itself
Senior iron ion, in the presence of SRB (sulfate reducting bacteria), it is possible to generates FeS composite, has hexavalent uranium relatively
Strong absorption, reducing property.Nano zero valence iron is 5:1 with the ratio of SRB (sulfate reducting bacteria), the major part of filler
For nano zero valence iron, and inoculate sulfate reducting bacteria, form biomembrane.Therefore, nano zero valence iron and sulfate reduction are relied on
Bacterium acts on removal uranium jointly.Conventional filter course 2 is divided three major types such as having bulk, tubulose, threadiness by shape.This device is adopted
With there being support bracket fastened installation form, filter course 2 position in water is fixed.Too much increase packed height only to increase
The volume of reactor, under conditions of wastewater flow and concentration are fixing, the increase of reactor volume can not significantly improve uranium
Clearance.But when filter course 2 height is less than 2m, mud just has the possibility being rushed out reactor, and then causes water outlet to be hanged
Increasing of float makes water outlet deteriorating water quality.Therefore, arranging filter course 2 thickness is 2.5m.The specific surface area of nano zero valence iron
The biggest with porosity, when waste water flows through, so that biomembrane is all right with waste water, and then raising water has
The mass-transfer efficiency of machine matter.It addition, current form shearing force at nano zero-valence iron surface, shear action can make biomembrane on filler
Increase will not be blocked up, can keep activity that biomembrane is higher and good mass transfer condition.
Waste water enters into the inside of cell body 1 by water inlet pipe 4, carries out flowing from top to bottom and will go in filter course 2, mistake
The material of filtering layer 2 is nano zero valence iron conjugate sulfate reducing bacteria, and waste water will be entered by nano zero valence iron conjugate sulfate reducing bacteria
Row processes, and in stable water layer 8, both so that cell body is flowed out in water body smooth transition, water body arrives steady through filter course 2 simultaneously
Determine water layer 8 can also react further.Outlet canal 10 end arranges monitoring device 9, and the water quality after monitoring processes is
No up to standard.Owing to uranium is a kind of radioelement, it is contemplated that safety factors, block last layer armored concrete around cell body
Body of wall, thickness of wall body is set to 240mm, isolates radiation with this.Dissolved oxygen in water body exceedes certain concentration, can make
Obtain uranous and be oxidized to hexavalent uranium, do not reach removal effect.Therefore, will strictly control reactor is anaerobic state.Process
Principle is:
1, to have particle diameter little for nano zero valence iron (nZVI) conjugate sulfate reducing bacteria, and specific surface area is big, and reactivity is high
Advantage, numerous studies show that nano zero valence iron not only can reduce the pollutant such as the various heavy removed in water body.Nanometer zero
Can under the common or compound action of the multiple mechanism such as valency ferrum is co-precipitated in surface chemistry reduction, complexation, precipitation, adsorbs, flocculation
Realize multiple pollutant in aqueous solution synchronize remove with repair it is considered to be have most application prospect pollutant control material it
One.
2, in the extracting solution of pale reddish brown lucerne place, Helianthi, tea rich in hydroxyl, carbonyl, functional group and the uranium complexation such as amino
Iron ion in-situ reducing, as reducing agent, coating agent and uranium bonding agent, is become nano zero valence iron by the plant biomass such as albumen, system
For obtaining the zero-valent iron material in this device packing layer so that it is effluent from uranium mining and metallurgy effectively can be administered.
3, flocculation Zero-valent Iron can produce substantial amounts of Fe when processing uranium (VI)2+And Fe3+, both of which can occur hydrolysis anti-
Should (Fe2++2H2O——Fe(OH)2↓+2H+；Fe3++3H2O——Fe(OH)3↓+3H+), form wadding respectively
The Fe (OH) of shape2With Fe (OH)3Precipitation.Increasing with pH value of solution, reaction is constantly carried out to the right.Two kinds are deposited in
During precipitation, to the UO in water2 2+There is good absorbability, also can improve UO2Settling property.And Fe
(OH)3It is also possible to continue hydrolysis, form Fe (OH)2+、Fe(OH)+Deng complex ion, these ions also have the strongest
Cohesion performance.Fe2+And Fe3+Hydroxyl hydrated ion and the cooperation ion generation of uranium that hydrolytic process is formed are adsorbing by force
Weak relevant with by dimer or even the polymer flocculation sediment of formation mixing of building bridge.Fe(OH)2+、Fe(OH)+Micelle
Positively charged, uranyl carbonate complex anion can be produced adsorption and make electrically to neutralize, uranyl carbonate complex anion electric charge
Amount reduces, and repulsive energy reduces, and this is also beneficial to flocculation sediment.
4, reduction mechanism
As under conditions of anaerobism, sulfate reducting bacteria can using Organic substances such as formic acid as electron donor, by the uranium of sexavalence from
Needed for son forms electron transport chain material compositions such as () cytochrome and therefrom obtains growth metabolism as electron acceptor
The energy wanted.Concrete reaction equation is as follows:
CH3COOH+4U6++4H2O→4U4++2HCO3 -+9H+ (1)
U(Ⅵ)+2e+→U(Ⅵ)↓ (2)
5, PRECIPITATION MECHANISM
SRB (sulfate reducting bacteria) may utilize SO under the reducing conditions4 2-For electron acceptor, organic carbon source supplies as electronics
Body, by SO4 2-It is reduced to H2S, the H of generation2S can be combined with metal ion and generate extremely difficult molten metal sulfide precipitation,
Can effectively remove the heavy metal in waste water.Concrete reaction equation is as follows:
HCOOH+SO4 2-→H2S+2CO3 - (1)
H2S+M→MS+2H+ (2)
In formula, M represents heavy metal
6, adsorption mechanism
