The invention belongs to water-treatment technology field, and in particular to a kind of high molecular heavy metals flocculation plant.
Background technology
Heavy metal wastewater thereby refer in the industrial processes such as mining and metallurgy, machine-building, chemical industry, electronics, instrument discharge containing weight
The waste water of metal.Heavy metal（Such as contain cadmium, nickel, hydrargyrum, zinc）Waste water is to an environmental pollution most serious and to mankind's harm maximum
One of industrial wastewater, its water quality and quantity is relevant with production technology.Heavy metal in waste water can not typically decompose destruction, Zhi Nengzhuan
Move its existence position and change its Material Form.Processing method is to reform production technology first, uses no or little the big weight of toxicity
Metal, in production site, treatment in situ is processed frequently with chemical precipitation method, ion exchange etc., a huge sum of money in the water after process
Category can be discharged or reuse less than discharge standard.Form new heavy metal enriched product to recycle as far as possible or in addition innoxious place
Reason.
Heavy metal chelating agent is a kind of chemical industry medicament with heavy metal ion strength chelating, because of PH that can be in room temperature and very wide
In value condition and range, with the Cu in waste water2+ 、Cd2+、Hg2+、Pb2+、Mn2+、Ni2+、Zn2+、Cr3+Enter etc. various heavy metal ion
Row chemical reaction, and be quickly generated insoluble, low water content at short notice, the flocculent deposit for removing easily filtered, so as to reach
To the purpose of the heavy-metal ion removal from water, the heavy metal chelating agent so chemicals are otherwise known as.Good heavy metals trapping
Agent is strong sequestering due to it, react can not only be in room temperature and very wide pH value condition and range in carry out, and do not receive heavy metal from
The impact of sub- concentration level.Even if containing complex composition in handled waste water, also can each heavy metal species in primary sedimentation waste water
Ion, makes waste water reach discharge standard.
But, current heavy metal chelating agent is in mainly powder, is carried out by way of feeding intake and staticly settling, this side
Although formula can Adsorption of Heavy Metals, the heavy metal waste liquid to low concentration has that adsorption effect is not good, and process time length etc. is asked
Topic, causes the reduction of whole treatment effeciency.
The content of the invention
It is an object of the invention to provide a kind of high molecular heavy metals flocculation plant, of the invention to have flocculating effect good, filter
Effect is good, good stability.
A kind of high molecular heavy metals flocculation plant, including screen plate, one-level fix aluminium sheet, one-level heavy metal Flocculent plate, two
The fixed aluminium sheet of level, two grades of heavy metal Flocculent plates, it is in I shape that the one-level fixes aluminium sheet and two grades of fixed aluminium sheets, and docks to be formed
One-level heavy metal Flocculent plate is placed in cavity, the cavity, the one-level is fixed in the groove of aluminium sheet upper end and is provided with screen plate,
Two grades of heavy metal flocculants are provided with the groove of described two grades fixed aluminium sheet lower ends, the one-level fixes aluminium sheet and two grades of fixations
Aluminium sheet center is provided with oblique gate hole plate, and the screen plate adopts rustless steel screen plate, the one-level heavy metal Flocculent plate and
Two grades of heavy metal Flocculent plates adopt micropore heavy metal Flocculent plate.
The high molecular heavy metals flocculation plant of the present invention, from screen plate water inlet, by the filtration of screen plate by waste water
Grain material is filtered, and reduces the particulate matter of waste water；Waste water after filter plates fixes the oblique of aluminium sheet by one-level
Gate hole plate carries out flow path guiding, waste water is passed through in one-level heavy metal Flocculent plate, by one-level heavy metal Flocculent plate
Hole carries out heavy metal adsorption, and using the heavy metal Flocculent plate of microcellular structure its Large ratio surface can be made full use of, and increases contact
Area, so as to improve heavy metal adsorption effect；The waste water that Jing one-level heavy metals Flocculent plate is filtered can be by most heavy metal
Ion remaval, subsequently into two grades of fixed aluminium sheets, by the oblique gate hole structure of the second fixation aluminium sheet secondary liquid flowing is carried out
It is oriented to, waste water enters two grades of heavy metal Flocculent plates；What two grades of heavy metal Flocculent plates were remained after one-level heavy metal Flocculent plate is adsorbed
Heavy metal ion adsorbed, the mode of second adsorption greatly reduces the content of heavy metal in waste water, improves adsorption efficiency and inhales
Attached effect.
Preferably, the gate hole plate angle of inclination during the one-level fixes aluminium sheet and two grades of fixed aluminium sheets is 30 degree, it is described
The whole height of gate hole plate is for the thickness of fixed aluminium sheet.
Current enter small-bore and can form more strong current recoil from large aperture region, can substantially reduce water flow velocity
Degree, the inclination of the gate hole plate can feed water to flow and provide circulation angle, can play good fluency, can reduce waste water and enter
The recoil strength of row Flocculent plate, when angle of inclination is 30 degree, the fluency of current is best.
Preferably, the screen plate adopts multiple layer metal web frame, the wire netting aperture is 0.3-1.2mm.
The screen plate aperture structure that the wire netting of multiple structure is formed is relatively stable, simultaneously because the structure for filtering layer by layer makes
Significantly extended with the life-span, filter effect is guaranteed, screen plate can be filtered the granule in waste water, no
The turbidity of waste water is reduced by only, while heavy metal Flocculent plate plays a protective role, granule is prevented by Flocculent plate pore plugging.
Preferably, the hole of the one-level heavy metal Flocculent plate is 0.01-0.1mm, two grades of heavy metal Flocculent plates
Hole be 1-8 μm.
The effect of staged care can be played using the different heavy metal Flocculent plate in aperture, by one-level heavy metal Flocculent plate
After carrying out a large amount of adsorption treatment, concentration of heavy metal ion is substantially reduced, now using two grades of heavy metal Flocculent plate energy in low aperture
Enough that the higher waste water Adsorption of Heavy Metal Ions of dispersion is reached into double purification effect, the heavy metals ion after process is dense
Degree is lower, and clarity is higher.
Preferably, the heavy metal Flocculent plate using sodium polyacrylate as raw material, be aided with foaming agent, aminating agent with
Xanthic acid agent, sodium polyacrylate is mixed to form platy structure with foaming agent, and foamed reaction forms microcellular structure, aminating reaction
Pore type Flocculent plate is formed with xanthan acidification response, the foaming agent adopts diisopropyl azodiformate, the aminating agent to adopt
With diallylmethylamine, xanthic acid agent using Carbon bisulfide sodium hydroxide solution.
Preferably, the proportioning of the one-level heavy metal Flocculent plate is as follows：100 parts of sodium polyacrylate, foaming agent 15-20
Part, aminating agent 50-70 parts, xanthic acid agent 50-70 part.
Preferably, the proportioning of two grades of heavy metal Flocculent plates is as follows：100 parts of sodium polyacrylate, foaming agent 8-12 parts,
