Abstract
The invention discloses a kind of methods of solid impurity in removal paper waste, magnetic metal particle is uniformly poured into paper waste first, by carrying out high-speed stirred to paper waste, the mode heated simultaneously to paper waste makes magnetic metal particle be evenly distributed, paper waste is stood into 10~15min again, keep magnetic metal particle and the solid impurity in paper waste sufficiently be bonded, then magnet is put into paper waste, magnetic metal particle is adsorbed, takes the solid impurity in paper waste out of.The present invention uses magnetic metal particle as carrier, removes the solid impurity in paper waste under the cooperation of magnet, since the equal band of these three metals is magnetic, can be attracted by magnet, so can smoothly take the solid impurity in paper waste out of.
Description
Technical field
The invention belongs to a kind of methods of solid impurity in technical field of sewage more particularly to removal paper waste.
Background technique
Paper industry is that water consumption is big, heavy-polluted industry, contains a large amount of pollutants in paper waste, including black liquor
With some solid impurities, if leave paper waste discharge, it will ecological environment is caused to seriously threaten with human health.
It is general that it is removed in such a way that filtering is fished for for the solid impurity in paper waste, that is, pass through filter
Net is filtered operation to paper waste, recycles the solid impurity in paper waste, but this mode operate it is more many and diverse, when
When the amount of paper waste is more, take the mode of filtering very many and diverse, so a kind of simple and quick mode is needed to recycle papermaking
Solid impurity in waste water.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, provide a kind of method for removing solid impurity in paper waste, can
The quickly solid impurity in removal paper waste, it is easy to operate.
In order to achieve the above objectives, a kind of the technical solution adopted by the present invention are as follows: side for removing solid impurity in paper waste
Method, comprising the following steps:
(1) magnetic metal particle is uniformly poured into paper waste；
(2) high-speed stirred is carried out to paper waste, while paper waste is heated；
(3) stir, heat after, by paper waste stand 10~15min, enable magnetic metal particle in paper waste
Solid impurity be sufficiently bonded；
(4) magnet is put into paper waste, adsorbs magnetic metal particle, takes the solid impurity in paper waste out of；
(5) step 1 is repeated to step 4.
In a preferred embodiment of the present invention, the magnetic metal particle is the hybrid particles of iron, cobalt, nickel these three metals
Object.
In a preferred embodiment of the present invention, the partial size of the magnetic metal particle is 0.5mm~10mm.
In a preferred embodiment of the present invention, in step 2,200 DEG C~400 DEG C are heated to paper waste.
In a preferred embodiment of the present invention, in step 2, paper waste is stirred using stirring rod or blender.
In a preferred embodiment of the present invention, the magnet is native magnet or electromagnet.
The invention solves the defect existing in the background technology, the present invention have it is following the utility model has the advantages that
(1) it is matched, effectively the solid in paper waste can be adsorbed with magnet using magnetic metal particle,
Smoothly solid impurity is taken out of after magnet is taken out；
(2) stirring can make magnetic metal particle be evenly distributed, so as to inhale to a wide range of interior solid impurity
It is attached；
(3) heating can be such that magnetic metal particle is preferably combined with the solid impurity in paper waste, to smoothly take
Out；
(4) magnetic metal particle using iron, cobalt, nickel these three metals hybrid particles object, due to the equal band of these three metals
It is magnetic, can be attracted by magnet, so can smoothly take the solid impurity in paper waste out of.
Specific embodiment
Below with reference to specific embodiment, the present invention is further described, a kind of side removing solid impurity in paper waste
Method, comprising the following steps:
(1) magnetic metal particle is uniformly poured into paper waste；
(2) high-speed stirred is carried out to paper waste, while paper waste is heated；
(3) stir, heat after, by paper waste stand 10~15min, enable magnetic metal particle in paper waste
Solid impurity be sufficiently bonded；
(4) magnet is put into paper waste, adsorbs magnetic metal particle, takes the solid impurity in paper waste out of；
(5) step 1 is repeated to step 4.
Wherein: the first step pours into magnetic metal particle in paper waste, can be uniformly distributed in magnetic metal particle
In paper waste；Magnetic metal particle is uniformly mixed by second step by way of stirring, while being heated, and magnetic gold is made
Metal particles can be contacted smoothly with the solid impurity in paper waste；Third step stirs, after heating operation, stands a period of time,
Guarantee that magnetic metal particle and the solid impurity in paper waste are sufficiently be bonded；4th step, is put into paper waste using magnet,
Magnetic metal particle is adsorbed, after the completion of absorption, magnet is taken out；5th step repeats step 1 to step 4, gives up to papermaking
Solid impurity in water is repeatedly removed, to guarantee removal effect.
Specifically, magnetic metal particle is the hybrid particles object of iron, cobalt, nickel these three metals,
Specifically, the partial size of magnetic metal particle is 0.5mm~10mm, and in this particle size range, magnetic metal particle
It is best with the attainable bond effect of solid impurity in paper waste.
Further, in step 2,200 DEG C~400 DEG C, at this temperature, magnetic metal are heated to paper waste
Grain can be preferably in conjunction with the solid impurity in paper waste, to smoothly take out the solid impurity in paper waste.
Further, in step 2, paper waste is stirred using stirring rod or blender, using stirring rod or
Person's blender can make magnetic metal particle be evenly distributed, so as to adsorb to a wide range of interior solid impurity.
Specifically, magnet is that native magnet or electromagnet can be to the magnetism in paper waste when using native magnet
Metallic particles is adsorbed；When using electromagnet, the magnetic metal particle in paper waste can not only be adsorbed, simultaneously
After taking-up, the presence or absence of electromagnetism ferromagnetism can be controlled by the on-off of circuit, be convenient for magnetic metal particle from electromagnet supernatant
Remove, so in the present invention, it is preferred to magnet be electromagnet.
The present invention uses magnetic metal particle as carrier, removes the solid impurity in paper waste under the cooperation of magnet
It removes, since the equal band of these three metals is magnetic, can be attracted by magnet, so can be smoothly by the solid impurity in paper waste
It takes out of.
Based on the above description of the preferred embodiments of the present invention, through the above description, related personnel completely can be with
Without departing from the scope of the technological thought of the present invention', various changes and amendments are carried out.The technical scope of this invention
It is not limited to the contents of the specification, it is necessary to determine the technical scope according to the scope of the claims.
