Abstract
The invention discloses a method for preparing a porous starch microsphere loaded potassium ferrate sewage treatment complexing agent. The porous starch microsphere loaded potassium ferrate sewage treatment complexing agent comprises the following components in percentage by mass: 50-70 percent of porous starch microsphere loaded potassium ferrate complex, 20-40 percent of polymeric ferric sulfate and 10-20 percent of diatomite, wherein the porous starch microsphere loaded potassium ferrate complex is a complex prepared by dissolving potassium ferrate in an aqueous solution of KOH with the pH of 12, adding porous starch microspheres for complexing and adsorbing. According to the novel water treatment complexing agent, a slow release effect on the oxidizing ability of the potassium ferrate is realized, and the sewage treatment capacity of the potassium ferrate is improved. In addition, due to addition of the polymeric ferric sulfate and diatomite, the complexing and adsorbing capacity of the complexing agent can be further improved, and the sewage treatment effect is improved.
Description
Technical field
The present invention relates to water-treatment technology field, be specifically related to the preparation method of porous-starch micro-ball load potassium ferrate sewage disposal recombiner.
Background technology
Global ecological environment goes from bad to worse, and water resources is shortage day by day.A large amount of trade effluents and sanitary sewage must can to a certain degree alleviated shortage of water resources through strict processing.Through years of researches, emerged the sewage disposal reagent of large quantities of excellent performances, wherein, potassium ferrate as a kind of to the mankind and Biosafety, the desirable water conditioner of environment non-secondary pollution has been obtained to research widely.Studies have shown that in a large number: potassium ferrate can not only be removed water pollutant and some carcinogenic chemicals, and in drinking water source and wastewater treatment process, itself does not produce the carcinogenic material of any mutagenesis, there is the security of height.In the aqueous solution, there is rapidly oxygenizement in potassium ferrate, and COD in sewage is played to good oxygenizement, and degradation production ferric hydroxide colloid is efficient adsorption flocculation agent simultaneously.
Potassium ferrate all has strong oxidisability within the scope of whole pH value, and in acidic solution, its standard potential is 2.20V, is 0.72V in basic solution, and potassium ferrate even can discharge oxygen by water molecules oxidation.It is poor that this strong oxygenizement causes potassium ferrate in sewage treatment process, to be oxidized selectivity, and only the poisonous and harmful substances around potassium ferrate molecule can be oxidized, and remaining potassium ferrate can react with water molecules.Such result is water treatment DeGrain, and potassium ferrate loss is excessive, and use value reduces.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide the preparation method of porous-starch micro-ball load potassium ferrate sewage disposal recombiner, potassium ferrate is carried on to porous-starch microballoon and can alleviates the release rate of potassium ferrate, improve its oxidation capacity to pollutent, and then in the situation that potassium ferrate usage quantity is less, obtain good effect, improve the use value of potassium ferrate.
In order to achieve the above object, the technical solution used in the present invention is:
Porous-starch micro-ball load potassium ferrate sewage disposal recombiner, by mass percentage containing porous-starch micro-ball load potassium ferrate mixture 50～70%, bodied ferric sulfate 20～40%, diatomite 10～20%, the preparation method of porous-starch micro-ball load potassium ferrate sewage disposal recombiner is: add by mass percentage porous-starch micro-ball load potassium ferrate mixture 50～70%, bodied ferric sulfate 20～40% and diatomite 10～20%, after being uniformly mixed in drying receptacle, sealing is preserved;
The preparation method of described porous-starch micro-ball load potassium ferrate mixture is: take in the KOH aqueous solution that potassium ferrate is dissolved in pH=12, concentration is 1g/3～5mL, after dissolving completely, add 60～80% porous-starch microballoons of potassium ferrate quality, stir at ambient temperature, absorption load-reaction 24h occurs, after reaction finishes, filter, filter cake is put into the dry 20h of 50 ℃ of vacuum drying ovens, obtains porous-starch micro-ball load potassium ferrate mixture.
Tool of the present invention has the following advantages:
1, the present invention, with porous-starch micro-ball load potassium ferrate, in guaranteeing the oxidation capacity that potassium ferrate is good to sewage, has been alleviated the oxidation rate of potassium ferrate effectively, improves oxidation selectivity, can further increase the water treatment effect of potassium ferrate.
2, the present invention is with porous-starch micro-ball load potassium ferrate, and after potassium ferrate discharges completely, the porous part of spherex is also sewage treating material a kind of excellent property, eco-friendly.
3, in system, introduce bodied ferric sulfate, utilize the auxiliary potassium ferrate of efficient complex performance of bodied ferric sulfate to improve water treatment effect.In system, introduce diatomite, utilize diatomaceous micro-porous adsorption performance to remove the part that is difficult to oxidation and is difficult to be removed by complexing in waste water.
3, the present invention adopt composition good biocompatibility, without environmental toxicity, non-secondary pollution, meets the requirement of water treatment " greenization ".
