Embodiment
Do further to detail below in conjunction with the preferred embodiment shown in the accompanying drawing.
The effect that receives lorentz's force with the conductor cutting magnetic line is the same, also can receive the effect of magnetic field force during the motion of aqueous solution vertical magnetic field direction, and strong magnetic water technology also is based on this principle.Water belongs to polar molecule, and two Wasserstoffatomss are 104.5 ° of tension force and combine with a Sauerstoffatom, and Sauerstoffatom one end shows electronegativity; Wasserstoffatoms to contiguous water molecules has sucking action; This effect is linked to be one to water molecules just, and under 15 ℃ of normal atmosphere, the molecule number of water clusters is about 40.Some physicochemical property that water showed, like its freezing point, boiling point, vp, surface tension, thermal conductivity, and water is to the solvency power of other materials, and seepage force or the like all has relation therewith.If to mobile water; From vertical direction, introduce the influence in magnetic field, situation has just changed; The two ends of the apparent positive and negative electrical property of water molecules receive the reactive force in magnetic field; Distortionization can take place in the original form of water molecules, and Intermolecular Forces is also weakened, and therefore water clusters also diminishes and become molecular grouping more freely.Also corresponding change of physicochemical property that water is original.Electrolytical ionization product-negatively charged ion and positively charged ion in the solution can receive the action of a magnetic field power in the opposite direction and become estranged, and the hydration between ion and the small water molecule group is but strengthened.Flow through magnetic field when making cutting magnetic line movement when water and other fluid, and its charged ion or polar molecule all can receive the effect of Lorentz force.As far as ion, the zwitterion reversing motion, its crystallization probability descends, hydration, extent of hydration strengthens, and the original physical and chemical activity of ion is also corresponding to be weakened, and this result is very beneficial to the toxic action of reduction heavy metal ion; As far as polar molecule, the reduction of intermolecular reactive force (Van der Waals force) is broken up molecular grouping to diminish and is had higher activity.With the water molecules is example; Its molecular grouping drops to the association attitude less than 10 molecules by the association attitude of an original 20-40 molecule; The vigor of water molecules has also strengthened tens of times, and its corresponding physicochemical property all have significant change like character such as surface tension, solvency power, seepage force, thermal conduction power.
Based on above-mentioned magnetic activated water treatment technology principle and the biological water technology principle of film; The invention provides a kind of Sewage treatment systems; The mode that adopts the magnetic activating technology to match with membrane bioreactor; As shown in Figure 1, comprise sewage water inlet pipe road 100, inlet channel valve 200, membrane bioreactor 500 and water purification outlet conduit 600, and outlet conduit valve 700 and lift pump 800; Industry or sewage are got into through inlet channel valve 200 control back in the said membrane bioreactor 500 after treatment by inlet channel 100, extract quilt recycle or dischargings once more from outlet conduit 600 out by lift pump 800 again; Effluent stream before said inlet channel valve 200 successively is provided with strong magnetic activating device 300 of interior general formula and strong magnetic cascade filtration collection blowdown apparatus 400 by water (flow) direction in the way; Sewage is being got between the membrane bioreactor 500 through magnetic activating and filtration treatment.
The strong magnetic activating device 300 of general formula comprises at least one strong magnetic activating device 310 in said, and this strong magnetic activating device 310 is installed on the equipment or pipeline that need be magnetized; But said strong magnetic activating device 310 independent installation or a plurality of installation together; When a plurality of strong magnetic activating devices 310 are installed together on pipeline; A plurality of said strong magnetic activating devices 310 must be installed on the same circumferential line by uniform distribution; Like Fig. 4 and shown in Figure 5, synoptic diagram goes out the situation that 6 strong magnetic activating devices 310 evenly are installed on inlet channel 100 walls among the figure.
Like Fig. 2, shown in 3; Said strong magnetic activating device 310 comprises uncovered type shell 311, and the bottom in the shell 311 is placed with magnetic conductive part 312, and the top symmetry of this magnetic conductive part 312 is placed with first permanent magnetic part 313 and second permanent magnetic part 314; This two permanent magnetic part 313, be provided with between 314 at a distance from magnet assembly 315; And the magnetic pole of this two permanent magnetic part 313,314 reverses relatively, promptly one of them upwards another makes progress for the S utmost point for the N utmost point; Said first permanent magnetic part 313 and second permanent magnetic part 314 top placed first respectively again and gathered magnetic working part 316 and second and gather magnetic working part 317; This two gathers magnetic working part 316, leaves the space between 317, and two gather magnetic working part 316,317 upper surface be symmetrically formed that to gather magnetic workplace 318 also be the installation surface of strong magnetic activating device simultaneously; Said geometrical shape of gathering the installation site on magnetic workplace 318 and be magnetized equipment or the pipeline matches, and can be designed to cylinder, sphere, plane, the conical surface or Archimedes' helicoid according to the particular case of installation site; Said first permanent magnetic part 313 is similar with the magnetic intensity of second permanent magnetic part 314 etc., and both geomeries and material are identical, are all rectangular parallelepiped or square; Said first gathers magnetic working part 316 and second, and to gather the shape and the material of magnetic working part 317 also identical.
Through above-mentioned particular structure, two are gathered magnetic working part 316 and obtain two different magnetic poles respectively with 317 upper surface: one is the N utmost point, and another is the S utmost point.It is minimum that this unique texture and mounting means have dropped to the magnetic circuit loss, and its workplace magnetic field is gathered the magnetic effect and improved greatly, and magneticstrength reaches more than 20000 Gausses, the highest can be near 30000 Gausses, magnetizability improves greatly.The request for utilization different according to the system of being magnetized, said strong magnetic activating device 310 can be directly installed on system's of being magnetized (equipment or pipeline) outside surface, also can be placed on said strong magnetic activating device 310 to the system of being magnetized and gather on the magnetic workplace.When system's of being magnetized (equipment and pipeline) outside surface is installed, different because of the material of installation position, can lean on the magnetism in magnetic field to ferromagnetic substance, make above said strong magnetic activating device 310 tightly is adsorbed on, otherwise also can use clamps.
