Technical field
The invention belongs to Tailwater Depth process field, more specifically to a kind of composite potassium ferrate sustained disinfectant
And preparation method thereof and application method.
Background technology
With the extension of China's commercial scale and industrial type, substantial amounts of industrial wastewater is generated in production process.
Particularly in industries such as oil, chemical industry, electrolysis, printing and dyeing, weavings, not only the discharge capacity of waste water is big, and the physical chemistry of waste water
Property is complicated.Many industrial wastewaters have high COD, high chroma simultaneously, and containing various heavy, and BOD/COD values are very low, make
Biodegradability into waste water is poor so that the tail water after conventional treatment method still has certain COD contents, and colourity does not reach
It is marked with and in the presence of pathogenic microorganisms such as a large amount of bacteriums, virus, amoeba sporangiocysts, such as ordinary biofilter can only remove large intestine bar
The 80%~90% of bacterium, therefore, in the urgent need to tail water is carried out disinfection and decolorization after, could qualified discharge.
Potassium ferrate is a kind of new, efficient, nontoxic multifunctional water treating agent, has shown that it is special in terms of water process
Some advantages, by good characteristics such as its superpower oxidability and flocculation, decolouring, deodorization, sterilizations, are widely used at water
In reason field, this is that other water treatment agents are incomparable.Potassium ferrate not only can with broad spectrum activity having in oxidation removal water
Machine and inorganic pollution, it is particularly more notable to the organic pollution treatment effect of some difficult degradations, and potassium ferrate
Decolourize and notable, the traditional disinfection way such as chlorination of disinfecting power, often produce DBPs, and potassium ferrate exists
Poisonous and hazardous DBPs will not be produced in course of reaction.
But at present potassium ferrate also there are problems that applied to water process it is many.Because potassium ferrate oxidisability is extremely strong,
Make moist and easily decomposed when being heated, less stable, storage difficulty is larger.In addition, potassium ferrate is also extremely easy in decomposition in water, make
Potassium ferrate effective time it is very short, it is necessary to constantly add medicament, cost is higher, and if there is Fe in solution3+, Fe3+It is right
High ferro acid group has very strong catalysis reduction, and its presence will significantly reduce the stability of product, the intensity of this effect

Amount, calculates different carbon posts to the degradation rate of methyl orange, sees Fig. 3.
From Fig. 3 it will be seen that activated-charcoal column suffers from certain degradation capability to methyl orange made from the embodiment,
Wherein the incipient degradation effect of carbon post 2 and carbon post 3 preferably, reaches more than 95%, and the incipient degradation rate phase of carbon post 5 and carbon post 6
To relatively low, but also all more than 90%, and each carbon post all drops to less than 90% to the degradation rate of methyl orange after 5 days, former
Because composite potassium ferrate slow-releasing agent is when just starting throwing and being added to the water, the potassium ferrate molecule that part is not wrapped by exists quickly
Discharged in water, the potassium ferrate collective effect with cladding, oxidation Decomposition methyl orange molecule so that initial methyl orange degradation rate is very
It is high.And with the complete release of uncoated potassium ferrate molecule, only the potassium ferrate of remaining cladded type slowly discharges, decomposition water
In methyl orange so that follow-up methyl orange degradation rate declines, belong to normal phenomenon.
Because the cyclodextrin content of carbon post 5 and carbon post 6 is higher, the relative amount of potassium ferrate is relatively low, so as to methyl orange
Oxidability there is no carbon post 2 and carbon post 3 high, so relatively low for the degradation rate of methyl orange in the starting stage.Carbon post 1 and carbon post
3 potassium ferrate content is close, and carbon post 3 is higher than carbon post 1 to the degradation rate of methyl orange, and analysis reason is carbon post 3 containing modification
Bentonite, bentonite has certain absorption degradation ability to dye molecule.
In figure after 16 days, carbon post 1~4 suffers from certain decline for the degradation rate of methyl orange, and carbon post 5 and carbon post 6
85% or so is basically stable at for the degradation rate of methyl orange, and analysis reason is that the cyclodextrin content of carbon post 5 and carbon post 6 is higher,
It is preferable for the covering property of potassium ferrate so that potassium ferrate can be stablized in water and slowly discharge, so as to reach slow
The effect released, and the rate of release of the potassium ferrate of carbon post 1~4 is very fast, to the active ingredient potassium ferrate in later stage medicament
Content is reduced, and the amount of release also decreases, and causes the degradation rate of methyl orange to there has also been certain decline.This embodiment illustrates
Carbon post 5 and carbon post 6 have good and stable slow release effect.
