Description

A kind of dye waste water treatment method
Technical field
The present invention relates to technical field of waste water processing, particularly a kind of dye waste water treatment method.
Background technology
Dyestuff is during production and processing, and in addition to being normally processed using water, some is with the shape of waste water Formula is discharged, and waste water from dyestuff is after discharge if cannot handle well, it is easy to earth's surface and underground water pollution are directly contributed, these Water often brings irreversible injury once being quoted by animal and people.Titanium dioxide series catalyst is mainly utilized at present The degradation of dyestuff is carried out under natural light, but due to the wider band gap of titanium dioxide, makes this kind of catalyst only special Instrument and consume competence exertion under conditions of a large amount of non-renewable energy resources simultaneously and act on, and catalytic process take it is longer.
Invention content
To solve problem above, it is an object of the invention to provide a kind of dye waste water treatment methods.
It is realized the purpose of the present invention is technical solution in this way, a kind of dye waste water treatment method, including following Step：

Step 2：Waste water in step 1 in grille well is introduced in sedimentation basin, carries out precipitation process；
Step 3：Upper strata waste water in step 2 in sedimentation basin is introduced in regulating reservoir, adds conditioning agent by the pH value of waste water；
Step 4：Waste water after adjusting pH value in step 3 is introduced in Photoreactor, catalyst is added in, carries out catalysis drop Solution reaction；The catalyst is has loaded Fe2+Porous silica material and H2O2；
Step 5：Liquid in Photoreactor is introduced in filtering ponds, is filtered processing, filtrate qualified discharge.
Further, Fe in the catalyst2+With H2O2Molar ratio be 1：15.
Further, agitating device is equipped in the regulating reservoir.
Further, it is described to have loaded Fe2+Porous silica material aperture be nanoscale.
Further, the conditioning agent in the step 3 is one or both of NaOH and KOH.
By adopting the above-described technical solution, beneficial effects of the present invention are：The present invention is by Fenton reagent in light reaction Photocatalytic degradation reaction is carried out in device, Fenton reagent is has loaded Fe2+Porous silica material and H2O2, loaded Fe2+It is porous Silicon materials act not only as Fe2+Supplier, and porous silica material can adsorb dyestuff so that degradation of dye Process greatly shortens, and degradation efficiency greatly improves.
