Description
Technical field
The present invention relates to magnetic-coagulation water-treatment technology field more particularly to a kind of High-gradient Magnetics for magnetic-coagulation water process
The magnetic field arrangement of separator.
Background technique
Magnetic-coagulation is magnetic powder to be added in conventional coagulation process, and be effectively combined magnetic powder with coagulation wadding body, due to magnetic
The density of powder is big, therefore considerably increases the density of coagulation wadding body, accelerates the sinking speed of wadding body, and hydraulic surface loading is reachable
20-40m3/(m2H), much higher than the 1-2m of conventional coagulation3/(m2H), while effluent quality is good, can be with common quartz sand mistake
Filter compares favourably, and is discharged solid suspension SS < 5mg/L, turbidity < 1.0NTU, total phosphorus TP < 0.02mg/L, has brilliant remove
Phosphorus effect.The technical characterstic of magnetic-coagulation technique further include: extremely short coagulation and sedimentation time amounts to residence time < 20min, because
This occupied area is minimum；Since internal system has the magnetic powder of 5g/L or more, it is resistant to flow and solid loading impact, in height

Magnetic-coagulation technology can be widely used for all types of industries sewage and sanitary sewage disposal, and black-odor riverway is administered, lake river
Ground Water warfare, tap water depositing technology, seawater desalinization pretreatment etc..Magnetic-coagulation system is provided with sludge recirculation system simultaneously,
So that magnetic powder and coagulant are recycled in sludge, be conducive to save dosage of PAC.Magnetic powder in excess sludge is by recycling
After this system is discharged.Therefore, a stabilize the economy key factor of operation of magnetic-coagulation system is that magnetic powder will have the higher rate of recovery,
The recycling of magnetic powder is realized by high gradient magnetic separator.
However, the magnetic separator currently used for magnetic-coagulation system cannot usually be met the requirements, magnetic induction and gradient
Intensity is inadequate, and magnetic fields depth is shallower, not strong enough to the active force of magnetic powder, cause magnetic powder (its partial size be generally 20 microns with
It is interior) magnetic force recycling cannot be relied on well under the shearing force that sludge quickly flows, the magnetic powder proportion of goods damageds are higher, serious shadow
The normal operation of magnetic-coagulation system is rung.In addition, magnetic separator design is unreasonable, the waste of permanent-magnet material is also often resulted in,
Lead to magnetic separator higher cost.The above defect is caused because magnetic field arrangement is unreasonable in magnetic separator after all
, magnetic field arrangement cannot meet the requirement under magnetic-coagulation operating condition to magnetic powder recycling well.Magnetic field arrangement is the pass of magnetic separator
