Abstract
The New Magnetic Field Controlled kind and preparation method thereof that the invention discloses a kind of for magnetic separation technique, wherein the raw material of magnetic carrier is aggregate, steel slag, binder and reducing agent；Preparation method is to mix aggregate, steel slag and reducing agent, 50 meshes are crossed after broken obtains mixture, adding water and stirring into binder makes binder dissolve to obtain binder solution, amount of water is the 40-50% of mixture quality, then mixture and binder solution are mixed and stirred for uniformly, granulating and forming is the pellet of 3-12mm, by the pellet it is dry to water content less than 10%, in the magnetic kind to obtain the final product of 350-1300 DEG C of calcining 0.5-8.0 hours.Magnetic kind of the present invention can be applied to city black-odor riverway, sanitary sewage and industrial wastewater secondary treated wastewater advanced treating, and the advanced treating and resource utilization of industrial wastewater may be implemented.
Description
Technical field
The invention belongs to magnetic separation technique magnetic kind preparation technical fields, and in particular to a kind of for the novel of magnetic separation technique
Magnetic kind and preparation method thereof, the polluter for going in the water such as oil removal, heavy metal, to have the function that purifying water body.
Background technique
Magnetic field itself is a kind of field with special energy, is led through the processed water in magnetic field or aqueous solution, optical property
The characteristic of electric rate, dielectric constant, viscosity, chemical reaction and surface tension and absorption, cohesion and electrochemical effect etc.
Measurable variation is all produced, and after removing magnetic field, this variation is able to maintain a few hours or a couple of days, has memory effect
It answers.Due to the presence of these phenomenons, magnetic technology is always research hotspot for many years.
Magnetic separation technique is a kind of technology that substance is carried out to magnetic field processing, and the application of the technology has penetrated into each neck
Domain, the technology are the difference using element or component magnetic susceptibility, substance are carried out magnetic field processing by external magnetic field, to reach
A kind of emerging technology of idetified separation process.With the appearance of high-intensity magnetic field, HGMS technology, the application of magnetic separation technique
From separation ferromagnetism bulky grain to removal weak magnetic and diamagnetic fine particle, from initial sorting mineral, coal desulfurization
Treatment of Industrial Water is developed to, develops to point between diamagnetic fluid homogeneous mixture component from magnetic and nonmagnetic elements separation
From.As clean, energy-efficient emerging technology, Magneto separate would indicate that tempting development prospect.
Magnetic separation method had become an emerging water treatment technology in recent years.Magneto separate is as physical processing techniques in water
Many successful applications are obtained in processing, show many advantages.Magneto separate is divided using the magnetism of impurity particle in waste water
From can make them that there is magnetism using magnetic inoculation technique for particle non magnetic or weak magnetic in water.By external force magnetic field
Effect, suspended solid magnetic in waste water is separated, to achieve the purpose that purified water.Currently, magnetic separation technique
Comparable achievement is obtained in terms of food, oily waste water, municipal sewage and treatment of dyeing wastewater, for heavy metal oils, superfine
Suspended matter, especially pathogenic microorganism, bacterium, algae removal have fairly good effect, and some has been used for actual waste water processing, phase
Believe the continuous maturation with the technology, magnetic separation technique processing waste water has a good application prospect.
Summary of the invention
A kind of New Magnetic Field Controlled kind and preparation method thereof for magnetic separation technique, it is characterised in that its raw material is by mass percentage
It constitutes are as follows: aggregate 50-60%, steel slag 30-40%, binder 5-20%, reducing agent 5-30%；The aggregate was 50 meshes
Natural Black Warrior stone；The steel slag is the substance rich in ferriferous oxide that iron-containing mass percent is not less than 20%；The bonding
Agent is bentonite or any binder that balling-up granule strength can be improved；The reducing agent is the activity of Industrial Waste Water Treatments factory
Sludge.
A kind of preparation method of New Magnetic Field Controlled kind, its step are as follows:
It is broken to be rolled into powder first by basalt crusher, bulky grain is screened out with 50 mesh sieve.
The steel slag that larger particles are screened out with 50 mesh sieve leaves powdered steel-making slag powder.
Aggregate 50-60% is measured, steel slag 30-40%, reducing agent 5-30% are adequately mixed.
Take binder 5-20% that the 40-50% that amount of water is mixture quality is added, stirring makes binder dissolve to obtain binder
Solution.
Mixture and binder solution are mixed and stirred for uniformly, granulating and forming is the pellet of 3-12mm.
It is less than 10% by made particle drying to moisture content.
By dried particle in 350-1300 DEG C of calcining 0.5-8.0 hours up to magnetic kind.
Claims (2)
