Description
Technical field
The invention belongs to field of water treatment equipment, more particularly to a kind of magnetic method sewage-treatment plant, sewage can apply to
Treatment industry, for industry, the processing of sanitary sewage, it is particularly applicable to the larger emergent sewage disposal of water.
Background technology
It is a kind of new method developed in recent years to carry out sewage disposal using the characteristic of magnetic.Its general principle is：Water
In have the material of magnetic or magnetic suck characteristic directly adsorbed under the action of a magnetic force and extract disengaging water body；Magnetic compared with
Material that is weak or not possessing magnetic suck characteristic, then iron powder and coagulant are added to water body, due to the particle diameter very little of iron powder, had
Very big specific surface area, adsorption capacity is stronger, is combined under the synergy with coagulant with pollutant, and interconnection forms larger
Bulk structure, aggregation, concentration, then into the magnetic field formed by magnet, is caught by magnetic field, adsorbs, extracted from water
Come, reach the purpose to purify water.Because the effect of magnetic field force is far longer than gravity and viscous force effect so that this technology has
The advantages of more, these advantages are small etc. including efficient, quick, energy-conservation, equipment volume.Therefore this method obtains in every field
To developing rapidly, in recent years except outer in industrial circle application, and in city domestic sewage processing, river course, lake pollution handle,
Drinking water treatment etc. is applied.In the technical process of numerous magnetic methods processing sewage, coagulation is added in accessing pending water
It is one of wherein more common method that agent, iron powder and flocculant, which carry out flocculation treatment,.But because iron powder is by the magnet on magnetic drum
It after absorption, can be magnetized, will assemble after magnetization because of attracting each other, so as to reduce surface area, influence iron powder in water
The attraction of pollutant, finally influences wastewater treatment efficiency.Simultaneously as iron powder has magnetic, will be mutual because of own magnetic force
Attract and be gathered in the side of reaction tank and pipeline, the less position of angle uniform flow, cause the loss of iron powder.The present invention be exactly in order to
Overcome these shortcomings, improve efficiency and carry out, this method can make it that iron powder demagnetizes before sewage is re-entered into, and make magnetic
Disappear, to improve efficiency.
The content of the invention
It is an object of the present invention to provide a kind of magnetic separation sewage treatment unit of new structure.Realize the technical side of the invention
Case is as follows：A kind of magnetic method sewage-treatment plant, including reaction tank, mixer is provided with reaction tank, top is provided with charge pipe, can be with
Iron powder, coagulant required for adding etc..Bottom is provided with sewage water inlet pipe, and the side on top is provided with outlet pipe, the side of bottom
Provided with conveying pipeline, outlet pipe is connected by control valve with seperator, and seperator is provided with drainpipe and next stage processing pond phase
Connection；The bottom of seperator sets dirt accommodating groove, and dirt accommodating groove is connected by emissions control valve with emissions pipe；
Magnetic drum is set in seperator, magnet is uniformly arranged on the inner surface of magnetic drum, the rotation direction of magnetic drum is identical with the flow direction of water；
One end coupled reaction pond of conveying pipeline, which is provided with demagnetizer, and set Pulp pump, be moved back before iron powder re-enters into reaction tank
Magnetic；The other end of conveying pipeline sets material collecting tank, one end of fixed scraper plate is hinged on material collecting tank, the other end of scraper plate, which is taken, to be put in magnetic drum
Outer surface on, be close to magnetic drum outer surface under gravity, with the rotation of magnetic drum, by the iron powder of magnet adsorption from magnetic drum
Outer surface scrape off and enter in buildup groove, buildup groove enters the iron powder being collected into conveying pipeline together with moisture,
By demagnetizer in the presence of Pulp pump, iron powder demagnetization, return in reaction tank and reuse.
The present invention improves attraction of the iron powder to water pollutant, good sewage processing effect；Meanwhile iron powder can be reduced
Loss.
