Solvability, compressibility and mass transfer characteristic, make it a kind of and have the most active thundering reaction medium, instead
Answer pressure 22MPa, under the conditions of 22.1MPa, carry out oxidation Decomposition Organic substance using supercritical water as reaction medium.
During supercritical water oxidation, owing to supercritical water is all fabulous solvent to Organic substance and oxygen, the most organic
Oxidation can be carried out in oxygen-enriched homogeneous phase, and reaction will not be restricted because of alternate transfer；The highest reaction temperature also makes
Reaction rate is accelerated, and in the shortest reaction time, organic clearance can reach more than 99.99%.
In oxidizing process, C, H element in organic pollution finally change into carbon dioxide and water；N, S, P and halogen etc.
Hetero atom oxidation generates gas, oxyacid or salt；In supercritical water, salt or is formed solid presented in concentrated salt solution
Body granule and separate out, the water in supercritical fluid becomes clean water after supercooling.
As a preferred version of the present invention, above-mentioned PVA polymeric material is in water solublity Protection Product, first to water solublity
Protection Product carries out prerinse, removes the nucleic wherein adhered to.
Above-mentioned water solublity Protection Product such as working clothing, purify paper, overshoes etc., the most all oil-containing PVA polymeric material, certainly,
Wherein possibly together with nucleic, therefore the nucleic of attachment is carried out prerinse.
As another preferred version of the present invention, in step c, PVA solution is 100:1, PVA with the volume ratio of sodium citrate
Solution is 100:1 with the volume ratio of copperas solution.
Preferably, described acid is sulphuric acid or mass fraction is the sodium citrate solution of 10%.
Preferably, described acid be mass fraction be the sodium citrate solution of 10%.
Compared with prior art, the reaction of dissolving in present invention dissolving tank replaces the Fenton's reaction in common PVA processing method,
It is to say, be by PVA thermosol rather than to utilize hydrogen peroxide and Fe2+So that it is oxidation.
Supercritical water oxidation processes PVA polymeric material, and it is organic dirt of the most effectively degrading in the case of not producing harmful side product
A kind of new method of dye thing.
