Abstract
The invention discloses an acidic dye wastewater treatment agent, belonging to the field of sewage purification treatment. The treatment agent is prepared from polyaluminum chloride, ferrous sulfate, active silica, oxydol, activated carbon and chlorine dioxide. All the components are uniformly stirred and completely dissolved at room temperature. The application temperature is 4-60 DEG C. The acidic dye wastewater treatment agent is suitable for treating acidic sewage. The Fenton reagent composed of the ferrous sulfate and oxydol according to certain parts by weight is combined with the inorganic flocculant polyaluminum chloride to form the main component of the sewage treatment agent; by using the active silica as the assistant, the suspended substance are quickly settled under the synergistic actions of the Fenton reagent, main component and assistant; and the combination of the activated carbon and chlorine dioxide can implement quick disinfection, decolorization and sewage purification. The acidic dye wastewater treatment agent has the advantages of low treatment cost, no corrosiveness, no toxicity and no secondary pollution after treatment.
Description
Technical field
The invention belongs to the dirty water decontamination handles field, relate to a kind of Acid Dye Wastewater treatment agent particularly.
Background technology
Waste water from dyestuff is one of main noxious industry waste water, is mainly derived from dye and dye intermediate production industry, is made up of the material run off in the mother liquor of various product and intermediate crystallization, production process and the sewage etc. that washes away ground.Along with going from strength to strength of dyestuffs industries, its factory effluent has become main pollution source of water body.
China is DYE PRODUCTION big country, and textile dyestuff industry development in recent years is quick.Different qualities according to dyestuff can carry out different classification to dyestuff, and dyestuff can be divided into by the chemical structure according to dyestuff: azoic dyestuff, anthraquinone dye, indigo revolve dyestuff, thioxine dyes, cyanine dyes, triarylmethane dye, heterocyclic dye; Dyestuff can be divided into according to application characteristic during dyeing: substantive dyestuff, thioxine dyes, vat dyes, matching stain, acidic complex dye, chemically-reactive dyes, glacial dye, oxidation dye, dispersed dye, basic dyestuff; The ionic state of often dissociating out in aqueous according to dye molecule in field of environment engineering and being divided into: anionic dyestuff, as substantive dyestuff, matching stain; Cationic dyestuff, as basic dyestuff; Nonionic dye, as dispersed dye.Chromophoric group in ionic and nonionic dye is all nitrogen-containing group or Anthraquinones mostly, in nitrogen-containing group, the reduction fracture of nitrogen key easily forms the virose amine of tool in waste water, and the dyestuff of Anthraquinones is difficult to be degraded due to aromatic structure wherein thus makes the more difficult decolouring of this kind of waste water from dyestuff.Reactive dyestuffs are the dyestuffs containing nitrogen key in typical chromophoric group, chromophoric group is connected with various active group, as cigarette sulfo group group, dichloro s-triazine active group, ethene sulfuryl etc., this kind of dyestuff is in dyeing and stamp process, the active group of dyestuff and fiber molecule form covalent bonds, make dyestuff and processbearing astrocyte entirety, due to the advantage such as its lovely luster, good water solubility, utilisation technology be simple, reactive dyestuffs are widely used in printing and dyeing industry.But the waste water containing these water miscible reactive dyestuffs is also one of the most unmanageable waste water, traditional water technology is not fine to these dyestuff treatment effects.Even if basic dyestuff makes water neutral and alkali dye strength very low during because its color and luster is very bright-coloured, the colourity of water body is also very high.Dyestuff containing heavy metal is mostly containing chromium, and chromium has carinogenicity.Dispersed dye do not exist in the solution in the form of an ion, and many dispersed dye have biological accumulation, and dispersed dye steady chemical structure, biodegradability is poor, and therefore, the traditional removal effect of water-treatment biological treatment system to dispersed dye is very poor.
Summary of the invention
Technical problem to be solved by this invention is for existing sewage disposal chemicals treatment used weak effect, sedimentation is slow, cost is high, equipment corrosion is serious defect, there is provided a kind of dye wastewater treatment agent, this treatment agent high-level efficiency, low cost, corrosion-free, nontoxicity.。
To achieve these goals, the present invention is achieved by the following technical solutions:
A kind of Acid Dye Wastewater treatment agent, the feed composition comprised is: polymerize aluminum chloride, ferrous sulfate, active silicic acid, hydrogen peroxide, gac, dioxide peroxide.
The feed composition of described Acid Dye Wastewater treatment agent, presses row weight part ratio composition: polymerize aluminum chloride 35-55 part, ferrous sulfate 15-25 part, active silicic acid 5-15 part, hydrogen peroxide 15-25 part, gac 2-10 part, dioxide peroxide 1-5 part.
The feed composition of described Acid Dye Wastewater treatment agent, preferably, presses row weight part ratio composition: polymerize aluminum chloride 40-50 part, ferrous sulfate 18-22 part, active silicic acid 8-12 part, hydrogen peroxide 18-22 part, gac 4-8 part, dioxide peroxide 2-4 part.
Further, the feed composition of described Acid Dye Wastewater treatment agent, preferably, presses row weight part ratio composition: polymerize aluminum chloride 45 parts, 20 parts, ferrous sulfate, active silicic acid 10 parts, 20 parts, hydrogen peroxide, gac 7 parts, dioxide peroxide 3 parts.
Described dye wastewater treatment agent at room temperature uniform stirring is all dissolved, use temperature 4 DEG C-60 DEG C, and being suitable for pH is acid sewage.
The invention has the beneficial effects as follows:
(1) the present invention is by the Fenton reagent by the ferrous sulfate of certain part by weight proportioning and hydrogen peroxide composition, and combining with inorganic flocculating agent polymerize aluminum chloride and forms sewage-treating agent host, take active silicic acid as auxiliary agent, three's synergy, rapid subsidence suspended substance; Gac is combined with dioxide peroxide, and Quick disinfection, decolouring, purify waste water.
(2) low, corrosion-free, the nontoxicity of processing cost of the present invention, non-secondary pollution problem after process.
