Description
Technical field
The utility model relates to the sewage treatment equipment of electroplating industry, is specifically related to the recovery system of nickel in a kind of electroplating wastewater.
Background technology
Electroplating industry all produces a large amount of plating nickel-containing waste waters every year, and directly a kind of wasting of resources is not only in discharging, and environment is caused severe contamination.Electroplate the processing of nickel-containing waste water at present and mainly use the method for regulating pH value in the waste water that nickel is precipitated, handle nickel-containing waste water in this way, not only be difficult to reach the environment protection emission requirement, and the nickeliferous product nickel content of gained is low, recovery difficult is big.
Summary of the invention
The utility model technical problem to be solved is: solve the problem that above-mentioned prior art exists, and provide that a kind of nickel organic efficiency is high, purity reaches 99%, the recovery system of nickel in low, the electroplating wastewater that reaches discharging standards of nickel content in the processed waste water.
The technical scheme that the utility model adopts is: the recovery system of nickel comprises circulation of elecrolyte bucket, rotating cathode Winning cell, resin absorption jar, adsorption liquid storage barrel and the electric control gear that connects successively in this electroplating wastewater; Circulation of elecrolyte bucket top has the electroplating wastewater import; Circulation of elecrolyte bucket bottom has electrolyte outlet and secondary electrodeposition solution inlet port respectively; Electrolyte outlet is through recycle pump, pipe connection to rotating cathode Winning cell inlet; The outlet of rotating cathode Winning cell connects the resin adsorption tanks, and the waste water after the absorption of resin absorption jar is divided into two-way, connects circulation of elecrolyte bucket and outer discharge pipe respectively.
In the technique scheme, have electrodeposition on the rotating cathode Winning cell and go out the nickel mouth, have rich nickel liquid relief outlet on the resin absorption jar.
In the technique scheme, the rotating cathode Winning cell is added with the pH value setting device.
In the technique scheme, reproducible cationic exchange coloum is installed in the resin absorption jar.
In the technique scheme, the input channel of adsorption liquid storage barrel is connected adsorption liquid liquid feeding pump and adsorption liquid Sendout pump respectively with output channel.
Principle of work:
At first will add sulfuric acid or sodium hydroxide, the pH value of solution will be transferred between the 2.5-6.5, and send into rotating cathode electrodeposition machine then and carry out electrodeposition according to the manufacturing technique requirent of nickel electrodeposition.Configuration solution PH value adjusting device is to guarantee the cathode efficiency in the electrolytic deposition process in the equipment.Solution constantly circulates in electrolytic deposition process.When the nickel ion concentration of solution being reduced to 0.2-0.5g/L, solution being drained into the resin absorption operation carry out adsorption treatment through electrodeposition process.Resin absorption adopts cationic exchange resin adsorption, through to the pH value of entering adsorption column solution and the control of flow velocity, guarantees through the solution nickel content after the adsorption treatment less than 1ppm.Solution after adsorption treatment 70% turns back to electroplating assembly line as wash water, and residue 30% can directly be discharged.After polymeric adsorbent is saturated, send into the regeneration of backwash operation, the solution containing nickel that backwash obtains is sent to the rotating cathode Winning cell, and the secondary electrodeposition is handled.
Equipment that the utility model adopted and technology have greatly reduced the discharging of electroplating wastewater, and will be wherein 99% nickel reclaim with the metallic state of purity 99%, entire treatment technology is carried out in airtight equipment; Reduced and the contacting of external environment, reduced pollution, had only waste water and metallic nickel in the product simultaneously, do not had mud; Stopped secondary pollution, therefore, the utility model nickel organic efficiency is high; Purity is good, and discharge of wastewater is up to state standards, good environmental protection.
