A treatment method for recovering nickel from nickel-containing waste liquid, involving an ion exchange resin, through adsorption, analysis and other working processes, to recover nickel from nickel-containing waste water, characterized in that the treatment process is to process nickel produced in the nickel production system After the nickel-containing wastewater is filtered, the ion-exchange resin is used to absorb and recover ionic nickel from the nickel-containing wastewater, and the nickel content in the waste liquid is absorbed to below 2mg/L before being discharged. A treatment method for recovering nickel in nickel-containing waste liquid of the present invention adopts ion exchange resin to absorb and recover nickel, and has the advantages of high nickel yield, fast analysis speed, high concentration of liquid nickel ions after analysis, and simple operation. At the same time, When the method is applied to actual production, it will not affect the acid balance and volume balance of the production system, can produce certain economic benefits, and can discharge the nickel electrolysis tail liquid up to the standard.
