Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with specific embodiment, and reference
Accompanying drawing, the present invention is further illustrated.
With reference to accompanying drawing 1, the invention provides a kind of coating wastewater cleansing and recycling equipment, the equipment includes passing sequentially through pipeline
The flotation tank 1 of connection, mechanical flocculation apparatus 2, regulating reservoir 3, Fenton oxidation tower 4, neutralization pond 5, filtering cloth filtering pool 6 and ultrafiltration apparatus 7.
Wherein, mechanical flocculation apparatus 2 sets three, is connected in parallel, can alternate run；Fenton oxidation tower 4 sets two, alternate run；

OK.
It is useless to part according to the water and water quality situation of coating wastewater links sewage during using equipment of the invention
Water remixes processing after anticipating.Pre-treatment Wastewater Pretreatment：It is demulsified in flotation tank 1 using acidization, by degreasing waste water
After phosphorized waste water mixing, adjustment defatting-bonderizing pH of mixed separates out higher fatty acids to 2~3, is dredged by higher fatty acids
The characteristic of water oleophylic reaches the purpose of separation, is conducive to demulsification；In addition, in acid condition, the anionic surface in waste liquid is lived
Property agent because decompose it is de- surely lose original balance, so as to be demulsified.Will be relatively low containing a certain amount of organic matter degreasing waste water and COD
Phosphorized waste water merging treatment, had so both saved demulsification medicament, and the chemical precipitation for phosphorized waste water again provides favourable acidity
Environment.The pretreatment of electrophoresis painting wastewater：Electrophoresis and painting wastewater major pollutants are paint composition granule, macromolecule resin, pigment,
Cosurfactant, heavy metal ion and small molecular organic solvent, its COD are higher, inorganic flocculating agent and organic-flocculation during reaction
Agent is used cooperatively.Electrophoresis waste water and painting wastewater mixing homogeneous carry out demulsification pretreatment in mechanical flocculation apparatus 2, make therein
Oxidation operation is decomposed, and is reduced COD, is easy to subsequent treatment.By materializing strategy, most macromolecule in waste water can be removed
Resin, surfactant, pigment, auxiliary agent and metal ion.
Then the waste water after two kinds are handled in regulating reservoir 3 is mixed, and realizes the regulation of waste water quality and water；Exist afterwards
The hydroxyl radical free radical produced in Fenton oxidation tower 4 using Fenton process removes the colourity and slightly solubility organic matter of coating wastewater.Fenton
The hydroxyl radical free radical oxidability that reagent is produced is extremely strong, the organic matter in energy oxidized waste water, generates water and carbon dioxide etc., reduction
COD.Or occur coupling or oxidation reaction, change their dissolubility and coagulating sedimentation.Meanwhile, occur in Fenton reagent
Series reaction meeting generating portion ferric ion, forms partial suspended thing and impurity in ferric hydroxide colloid, adsorbable water.For
Further removal COD5 and colourity are, it is necessary to carry out advanced treating, and this advanced treating adds hyperfiltration treatment technique using filter cloth.
In filtering cloth filtering pool 6, the impurity in water outlet is separated using filtering material, the suspension after Fenton's reaction in sewage and colloid substances are removed
Matter.Turntable filter chamber filtering accuracy is high, it is possible to achieve continuous filtering, cleaning efficiency is high, and water consumption is few.Filtering is to remove in waste water
Fine suspension matter and remaining oil emulsion, while SS concentration can be effectively reduced.And ultrafiltration technology afterwards can be removed further
The macromolecular substances gone in water and microorganism, make water quality reach Treated sewage reusing standard.The clarification of water handled through ultrafiltration apparatus 7,
COD5 is low, is excellent recycle-water.PH is adjusted in pH regulating reservoirs after advanced treating, makes water outlet pH 6~9.Through each sedimentation basin
The sludge of discharge, is transported outward after press filtration, reduction moisture percentage in sewage sludge are carried out in filter press.So effluent quality is reliably protected
Card, the even up to standard of Treated sewage reusing.
For the present invention preferred embodiment, but the present invention is not limited to above-mentioned embodiment to the embodiment, not
In the case of the substantive content of the present invention, any conspicuously improved, replacement that those skilled in the art can make
Or modification belongs to protection scope of the present invention.
