A kind of processing method purifying conversion apparatus for production line cleaning solution for uranium, comprising the following steps:
S1: chemical precipitation
Uranium conversion apparatus for production line cleaning solution is purified first to be collected by precipitation tank in term；HCl is added, is adjusted
Saving pH value of solution is 3；Sufficiently reaction after, be added NaOH, adjust pH value of solution be 10, make wherein uranium precipitated in the form of sodium diuranate；
S2: filtering
The S1 precipitated liquid generated is filtered with filter, recycles sodium diuranate；
S3: water-oil separating
Liquid removes wherein organic matter with oil water separator after the filter that S2 is generated；
S4: film process
By S3 it is separated go out water phase filter out wherein undissolved bulky grain with microfiltration membranes, then by microfiltration membranes clear liquid with receiving
Filter membrane is concentrated；
S5: ion exchange
The dope that nanofiltration membrane is isolated is passed through ion exchange column and carries out adsorption cleaning.
In the S3, the waste organic matter of generation is packed into container outward transport.
In the S4, the clear liquid that nanofiltration membrane is isolated enters letdown tank.
In the S5, ion exchange resin uses TP107 anion.
In the S1, steam is passed through by solution and is heated to 60~90 DEG C.
Remarkable result of the invention is: uranium purifying conversion apparatus for production line cleaning fluid composition is complicated, and uranium content is high, golden
It is high to belong to impurity content, metallic uranium can sufficiently be recycled by being handled using this method, by uranium concentration in relief liquor be reduced to 50 μ g/L with
Under, reach national emission standard, and avoid there are other in recycled metallic uranium using the uranium Selective adsorption of Special Resin
Metal impurities enrichment, convenient for the cycling and reutilization of nuclear material.
