The present invention uses following multinomial relevant speciality technology:
Magnetic field itself is a kind of field with special energy; The water or the aqueous solution crossed through magnetic field treatment; The characteristic of aspects such as its optical property, electric conductivity, specific inductivity, viscosity, chemical reaction and surface tension and absorption, cohesion and electrochemical effect all can produce measurable variation.
One, magnetic catalysis: the mechanism of catalyzed oxidation mainly is free radical reaction, and the active intermediate H2O2 that system produces then is the important initiator that forms radical.The magnetic catalytic unit of MNFP system is in the magnetic catalytic process, and the magnetoelectricity reaction through permanent magnetic strong magnetic field and pulse electromagnetic field produces active specy H2O2 and OH.
O2 that magnetic catalytic unit of the present invention produces through magnetoelectricity field electrolysis and extraneous available O2 reduces generation H2O2 on negative electrode.Quick oxidizing reaction and radical chain reaction take place in the organism in the magnetic catalystsystem, and organism is removed rapidly.The essential condition of organic pollutant at first is a magneticstrength in the magnetic catalytic elimination waste water, and the size of magneticstrength directly affects catalytic speed of reaction of magnetic and treatment effect.
Two, magnetic catalyzed oxidation: the magnetic catalyzed oxidation is a kind of high-level oxidation technology. so-called high-level oxidation technology (advancedoxidation process; Be called for short AOP); It is the technical process that can produce the great amount of hydroxy group radical; Promptly utilize physics such as various light, sound, electricity, magnetic and chemical process to produce a large amount of radicals; This radical has extremely strong oxidisability, can organic pollutant be decomposed effectively through free radical reaction, even be converted into the technical process of harmless inorganics (like carbonic acid gas and water etc.) up hill and dale.
Magnetic catalyzed oxidation technology is to utilize the single-stage magnetic technology, adopts permanent magnet material to make the positive one pole magnetic circuit device of strong magnetic.
1, two kinds of physical changes have taken place water molecules in the negative magnetic field of high strong-focusing: molecule is polarized (ordered arrangement) and is with electronegativity.O2 in airborne O2 and the water generates H2O2+OH and in water, produces quick oxidizing reaction and radical chain reaction under the negative electric field effect.In addition, the new life's that negative electrode produces hydrogen reduction is very capable, with pollutants in waste water generation reduction reaction.
When water, the gas mixed solution that 2, forms through oxygen-dissolving tower when water flowed through strong magnetic catalytic unit, two kinds of physical changes had taken place in water molecules in the positive pole field of high strong-focusing: molecule polarized (ordered arrangement) and becoming positively charged property.Anode makes pollutant oxidation be through direct electrolytic reaction: direct oxidation; And utilizing the negatively charged ion that electrode potential is lower in the solution to lose the extremely strong active substance of electronics shorter oxidisability generation lifetime at anode, they can decomposing pollutant.
Three, magnetic reduction: 1, the magnetic reducing apparatus is to utilize the single-stage magnetic technology, adopts permanent magnet material to make a strong magnetic negative unipolar magnetic circuit device.When water molecules was flowed through the negative magnetic field of high strong-focusing, two kinds of physical changes have taken place: molecule was polarized (ordered arrangement) and is with electronegativity.O2 reduction generation H2O2 produces the radical effect and impels the strong oxygenolysis of organism under the negative electric field effect.2, the permanent magnet pulse device is to utilize single-stage magnetic technology and electronics single-stage pulsed magnetic technology, adopts some permanent magnetism single-stage magnetic circuits and electronic impulse single-stage magnetic circuit, a single-stage pulse shear magnetic field of formation.When water molecules is flowed through the single-stage pulse shear magnetic field of high strong-focusing, molecule polarized (ordered arrangement).The electrically charged amount of particle institute in the waste water is reduced, and the reactive force between the particle reduces reduction.
Four, magnetoelectricity is separated: it is exactly with magnetoelectricity field and magnetic field superposition that magnetoelectricity is separated, to promote electrolytic process.Separate in the process at magnetoelectricity, field direction is vertical with the magnetoelectricity field orientation, and the waste water intermediate ion had both received the effect of magnetoelectricity field force, also receives the effect of magnetic field force, and its heading and rule change.Under the effect of Lorentz force, the ion motion track is complicated, has increased the collision opportunity to unionized electrolytic solution molecule, has promoted electrochemical reaction.
Five, magnetic cohesion: the magnetic cohesion is a kind of means of impelling solid-liquid separation, is a kind of treatment process of carrying the high deposition efficiency of solid matter, in general need not add the magnetic kind.The magnetic cohesion is exactly to make sewage pass through uniform magnetic field, because field gradient is zero, the magnetic-particle thing can not captured by magnet in the water, is gathered into macrobead but attract each other between the particle, thereby improves deposition efficiency.Because magnetic-particle has certain coercive force, even also can continue to produce cohesion after therefore leaving magnetic field.Its advantage is that there is not device blockage in the magnetic cohesion, need not add magnetic kind and tripping device, and is simple.Effect through magnetic field reduces the electrically charged amount of particle institute in the waste water, and the reactive force between the particle reduces, and the probability that mutually combines increases.
Six, magnetic-pulse: the magnetic-pulse device is to utilize single-stage magnetic technology and electronics single-stage pulsed magnetic technology, adopts some permanent magnetism single-stage magnetic circuits and electronic impulse single-stage magnetic circuit, a low frequency single-stage pulse shear magnetic field of formation.
Seven, magnetic flocculation: the magnetic flocculation method is simple to operate, need not add chemical agent, and sludge yield is few, and non-secondary pollution.
1, under the field of magnetic forece effect, utilize soluble anode to produce a large amount of positively charged ions, waste water is carried out coagulative precipitation.Under the situation of high-intensity magnetic field, the association phenomenon of water molecules temporarily is cracked, and water molecules becomes one polar molecule, because electrostatic interaction, the sewage molecule is difficult to do ordered arrangement, but is with the quiet polymerization of identical electrostatic pine in a large number, forms cotton-shaped polymer.
2, the effect electrolysis generates in little magnetoelectricity pond Fe2+, Fe3+.Has extremely strong activity; Under different pH conditions; Form multiple monokaryon hydrolysate, because the condensation that the monokaryon hydrolysate produces generates a series of multinuclear hydrolysates again; The polymer thread of hydroxyl is contained on final formation surface, and these hydrolysates have important effect to promoting flocculation.
Eight, magnetic microbattery: the ultimate principle of microbattery method is to utilize the iron of iron filings and the anode and cathode that the charcoal component constitutes small galvanic cell, is that electrolyte solution forms microbattery with the waste water that charges into.Its electrode reaction is following:
Negative electrode (C):
1/2O2+H2O+2e-＝2OH- E0＝+0.4V
Anode (Fe):
Fe＝Fe2++2e- E0＝-0.44V
The Fe2+ activity that in this reaction, produces is high, and the organic pollutant in the ability the efficient oxidation waste water changes its structural form, thereby degrades these pollution substances effectively, and reduces the colourity of waste water greatly.Fe2+ can generate Fe (OH) 2 colloids with the OH reaction that negative electrode produces, and has O2 to exist because reaction system is an open system, so Fe2+ can change into Fe3+ and generate Fe (OH) 3.Newborn Fe (OH) 2 and Fe (OH) the 3rd, the colloid flocculation agent that adsorptive power is higher, and the Fe2+, the Fe3+ that produce can also be with the gellings such as dye particles in the waste water together.Formation is the flocs unit at gelling center with Fe2+, Fe3+.Capture, hold under the arm and wrap up in and to adsorb the colloid of suspension heavy altogether.So during with micro-electrolysis treatment sewage.Redox degraded, electrochemistry, electro-adsorption and effects such as electricity flocculation, coagulation take place simultaneously, remove pollutent effectively.
Eight, nanofiber magnetic microbattery: with the NACF is negative electrode, and the Fe powder is an anode, the microbattery group of formation.Its separating mechanism comprises atom sieve effect and electrical effect.Charged ion on the nanometer felt and the ion in the liquid form pair ion, and the latter is removed simultaneously.The little duct of this felt and surface charge make size can be removed less than the ion in duct.
Nanofiber magnetic microbattery filtration method is lower than the pressure that reverse osmosis method needs, and therefore, process cost is also low than the latter, but treatment effect is identical.Generally speaking, the nanofiltration method can be handled and contain the inorganic sewage of concentration of heavy metal ion greater than 2000mg/L.
Nine, magnetic sterilization: magnetic field can make the part hydrogen bond rupture between water molecules; Generate excessive ultra-oxygen anion free radical; Because an amount of ultra-oxygen anion free radical has metabolism energy storage, conversion, waste discharge and the effect of defence disinfectant in life entity; Excessive lipid, damage nucleic acid, destruction glucide and the protein of then can destroying brings harm to life entity, and Here it is, and why magnetized water can germ-resistant reason.
Ten, magnetism is floating: the floating effect of magnetism is when electrolysis, because disassociation and organic electrolytic oxidation in the water are separated out hydrogen and oxygen respectively on negative electrode and anode; And produce a large amount of micro-bubbles, and these bubble sizes are very little, and dispersity is high; Adhere to the suspended solids in the water and float as carrier; In uphill process, can capture and adhere to that a large amount of contaminant particles and organism climbs up on top of the water in the water, reach isolating effect.
11, anti-, the scale removal of magnetic: under the situation of high-intensity magnetic field, the association phenomenon of water molecules temporarily is cracked, and water molecules becomes one polar molecule; It is adsorbed on the lime carbonate crystallite of harsh one-tenth; Form water molecules and lime carbonate crystallite molecular grouping, because electrostatic interaction, lime carbonate is difficult to do crystalline ordered arrangement; But, form cotton-shaped polymer in a large number with the loose quiet polymerization of identical static crystallite.The water molecules of crossing through magnetic field treatment can not only make because supersaturation is newly separated out the lime carbonate crystallite and on heat-transfer surface, is not bonded to dirt, also can soak into infiltration to existing dirt layer, and incrustation scale is produced sorption, constriction effect and loose gradually stripping off;
In nanofiltration (NF) and r-o-(RO) membrane sepn process, inorganic pollution is one of principal element that causes membrane flux decline.The inorganic pollution of film is meant that the insoluble divalent salts that is trapped after the concentration on the face surpasses certain saturation degree, forms crystal deposition on face, and cure into tight zone.Inorganic pollution will significantly reduce effective filtering membrane area, increase to see through resistance, reduce the permeable latus rectum and product water quality of film.Magnetic field and membrane process are combined the inorganic pollution that is used to prevent and reduce film.

Magnetoelectricity is the filter device (see figure 4) just; Sewage has become elementary flocculation state through impurity in strong magnetic catalysis-binominal distribution micron aeration-strong magnetic catalysis-(magnetoelectricity is separated) back water, and is mixed with a large amount of gases entering magnetoelectricities filter device 4 just, in many group 800Gs-3500Gs single-stage permanent magnetism magnetic groups 42 and 800Gs-5000Gs single-stage low-frequency pulse magnetic magnetic group 43; Under the vertical action of alternating magnetic field that produces; Further produce that magnetoelectricity is separated, the magnetoelectricity flocculation, magnetism is floating and magnetoelectricity catalysis, magnetoelectricity reduction reaction, and is that the magnetic kind is coagulated the wadding parcel by impurity under 15 microns-800 microns the effect of iron filings magnetic kind 46 and mixed gas at particle diameter; Rate of set is accelerated; Coagulate wadding by micron screen 44 interceptions, filter, tackled action of gravity settle to mud valve 45 places of mud in the magnetic kind through the gradient interception of 600 microns-5 microns of micron screen; When sludge settling when a certain amount of, mud valve is opened discharging mud automatically and is handled to collecting hopper dredger.In coagulating the process of being tackled by micron screen 44 of wadding a quilt with cotton, the magnetic kind 46 in the vertical alternating magnetic field and the permanent magnet of permanent magnetism magnetic group 42 are being done the movement at the uniform velocity of rule all the time along with the pulse-repetition of pulsed magnetic group.Micron screen 44 is produced the vibrations of certain frequencies and washes away,, also can form the pulse wave of certain power in this process medium and low frequency magnetic-pulse magnetic field.Under the acting in conjunction of magnetic kind 46, permanent magnet magnetic group 42 and pulsed magnetic magnetic group 43; Impurity in the water is difficult to suspension, covers or stops up micron screen surface and opening of sieve; Greatly improve the working efficiency and the work-ing life of filter screen, and effectively ensured the filtering accuracy of filter screen.In the water after magnetoelectricity filtering system 4 filter just just, the impurity more than 5 microns is tackled organic substances such as removal, mikrobe, bacteriophage and is killed basically, and water quality is limpid basically, free from extraneous odour, inclusion-free.Water from the first filter device of magnetoelectricity comes out gets into magnetoelectricity PH setting device through pipeline and further handles.
But magnetoelectricity PH setting device 11 adopts 15000Gs-50000Gs alternation magnetic pole high-intensity magnetic field as energy source; With magnetically permeable material as anode; Non-magnet material is as negative electrode; Strong carbon electrode acts on H in the water, O electronics, through polarized action change with the equilibrium water in positron-electron quantity, thereby reach the PH regulating effect.But under the strong carbon electrode effect of alternation magnetic pole high-intensity magnetic field, the pH value of water can reach pH value 6.5-8 in the moment of flowing through, and the water that comes out from magnetoelectricity PH setting device gets into strong magnetic reducing apparatus 3.
Strong magnetic reducing apparatus 3 is the circumference correspondence and is rearranged single-stage focusing annulus by permanent magnet and screen layer that 12 magneticstrengties are 8000-20000Gs, forms a negative unipolar focusing magnetic circuit device.When water molecules was flowed through the negative magnetic field of high strong-focusing, two kinds of physical changes have taken place: molecule was polarized (ordered arrangement) and is with-electronegativity.O2 reduction generation H2O2 produces the radical effect and impels the strong oxygenolysis of organism under the negative electric field effect.Under high strong-focusing permanent magnetic field, the water of flowing through is carried out magnetoelectricity reduction processing Na 2O generation certain amount of H 2O2 and make water generates primary oxidation reactor and magnetoelectricity chemical reaction; Organism such as the bacterium in the water, virus assimilate because of the nucleus electronics and strong oxidizing reaction in this course, and are killed in a large number; Each quasi-mineral in the water is polarized (ordered arrangement) at molecule, reaction force attenuation each other; Under the strong oxidizing reaction effect of H2O2, a large amount of separates from water, and becomes high strongly-magnetized water and get into little electrolysis fine filtering device 6, carries out the essence filter and optimizes.
Get into little electrolysis fine filtering device 6 (see figure 5)s fast after the supercharging of water process pipe pressurizing pump; Under the effect layer by layer of micron screen 61, nanometer filter screen 62 and nanometer microbattery composite screen 63; The form that all materials are removed with pure water basically in the water flows out by the road, can be used as industry or life pure water and directly uses.The water that comes out from little electrolysis fine filtering device incorporates rational trace element through mineralising system 7, to ensure health demand.
Mineralization device 7 is a raw material with the natural crystal, forms through HTHP gradient sintering special process sintering.Fully natural imitation underground water RKB component and structure, when water is out-of-date with the high pressure conditions high speed flow, mineralogical composition wherein can form the micro-component in the water with must ratio soluble in water, and the water of this moment can compare favourably with natural mineral water.And because passed through a series of magnetoelectricity treating processes of front end, the water of this moment is high reactivity, subset, weakly alkaline, moderate, the micro-scientific and reasonable magnetized water of hardness, so help the HUMAN HEALTH demand more than natural mineral water.
The present invention is provided with the water tank of one one constant volume at water outlet, a built-in recoil pump c who is complementary with single unit system, and recoil pump c is connected with flange or screw thread pipe fitting with positive back-purge system pipeline, controls its work automatically by the robotization stored program controlled.When water flow velocity, flow are lower than the stored program controlled preset value, recoil pump c start with positive back-purge system in the valve positive counter-flushing process of completion that matches.
Present embodiment is not owing to contain the metal ingredient of needs recovery in the water body, thus do not separate apparatus for recovering metal through magnetoelectricity, and directly get into filtering system at the beginning of the magnetoelectricity.All the other are with embodiment 1
