Abstract
The utility model discloses nickel-containing washing water treatment equipment. The equipment comprises a reverse osmosis unit, ion exchange resin units and an electrolysis unit which are connected in order. The equipment has the following positive effects: the energy consumption in the treatment process is low; the effluent water generated in the treatment process can flow back to workshops for use, thus reducing the water consumption in the workshops and the chemical addition dosage and sludge production in wastewater fields; high-purity nickel metal can be obtained; and the equipment has economic value, reduces the cost and is environment-friendly.
Description
Technical field
The utility model relates to nickeliferous rinse water treatment facility.
Background technology
The nickeliferous rinse water of tradition becomes mud with dosing method with nickel ion coagulant precipitation in the water, twice calcination to the smelter by the company of clearing again, and organism and moisture content in the nickel mud is removed in calcination for the first time.Advance smelting furnace again and carry out the secondary calcination and reach nickel fusing point (1455 ℃) and be cooled to the nickel plate, process Nickel Anode Plate, obtain high-purity metallic nickel in negative electrode through electrolysis.
Traditional nickel rinse water recovery system need pay add expenses for medicine, clear expense, the calcination energy consumption, cost is very high.And the dioxide gas that high-temperature calcination produced, belong to greenhouse gases, increase carrying capacity of environment.
Summary of the invention
The purpose of the utility model is the defective that overcomes prior art, and a kind of nickeliferous cleaning water treatment facility is provided.
The technical scheme of the utility model comprises:
A kind of nickeliferous rinse water treatment facility comprises the reverse osmosis units, ion exchange resin unit and the electrolysis cells that connect in order.
Further, this ion exchange resin unit and this electrolysis cells also attach to anti-wash tank.
Further, this reverse osmosis units also connects to mix well and deposits groove.
The positive progressive effect of the utility model is: the treating processes less energy consumption; What produce in the treating processes goes out flowing water and can be back to the workshop and use, and reduces the workshop water consumption, reduces the waste water field and add dose and mud generation, can obtain high-purity nickel metal tool economic worth; Reduce cost, and environmental protection.
Description of drawings
Fig. 1 is the synoptic diagram of the equipment of the utility model.
Fig. 2 is the working process synoptic diagram of the equipment of Fig. 1.
Embodiment
As shown in Figure 1, the nickeliferous rinse water treatment facility 100 of the utility model comprises reverse osmosis units 110, ion exchange resin unit 120 and electrolysis cells 130, to reclaim the nickel metal in the nickeliferous rinse water.
See figures.1.and.2 below and describe the working process of this equipment.
Can nickeliferous rinse water temporarily be stored in and mix well in the storage tanks, its tool regulating pondage function gets into reverse osmosis units 110 with nickeliferous rinse water then.Reverse osmosis units 110 is separating metal ion units main in this equipment 100, and the osmotic pressure difference of utilizing the film both sides is isolated nickeliferous ionic concentration liquid through the film of aperture between 0.01 μ m～0.1 μ m.
Utilize reverse osmosis units 110, nickeliferous rinse water is divided into the concentration liquid that comprises the nickel example and goes out flowing water, the nickel content in this concentration liquid is 10 times of nickel content in the rinse water, generation go out in the flowing water to pinch concentration extremely low, can directly get back to the workshop and utilize again.
This concentration liquid again through ion exchange resin unit 120, is utilized that same sex ion exchanges in charged effect base and this concentration liquid on ion exchange resin surface, nickel ion is adsorbed on the resin.Nickel ion in this concentration liquid is attracted on the resin basically at this moment, and the flowing water that goes out afterwards directly utilizes between carriage return again thereby this provides nickel removal nickel ion.
Carry out electrolysis afterwards, electrolytic efficiency can reach 95%.Electrolysis mainly utilizes added electric field to import direct current, makes the anode in the redox reaction discharge electronics, produces oxidizing reaction, and negative electrode is the reduction reaction of electron gain generation immediately then.Can obtain the high-purity nickel metal in negative electrode.
This ion exchange resin unit 120 also can be connected anti-wash tank 140 with this electrolysis cells 130.Backwash liquor capable of using (acid solution) carries out backwash the nickel ion desorption is washed out, and gets into electrolysis cells 130 thereupon and carries out electrolysis, obtains high-purity metallic nickel in negative electrode
It is following that the nickeliferous rinse water treatment technology of the utility model has advantage: going out flowing water and can be back to the workshop and use through reverse osmosis units (RO) and ion exchange resin treatment; Reduce the workshop water consumption; Reduce the waste water field and add dose and mud generation; Processing cost is reduced, and electrolysis acquisition high-purity nickel metal tool economic worth, and environmental protection.
