Abstract
The invention provides a method for recovering nickel from low-nickel waste water, which relates to a method for effectively recovering and enriching nickel from low-nickel solution output in wet metallurgy. The method is characterized by comprising the recovering processes: CNF-27 resin is adopted, the low-nickel waste water passes through the resin to adsorb the nickel on the resin, then, the nickel is back washed, and a nickel production process is carried out after the nickel is enriched. In the method, the CNF-27 resin is adopted, a fixed bed is used for continuous adsorption to lead the nickel in the solution to be adsorbed on the resin, so that the nickel is separated from other impurities, then, the nickel which is adsorbed on the resin is back washed by selecting different kinds of dilute acid according to a systematic solution condition. The concentration of the nickel washing solution can be enriched above 50 g/l and can directly return a production system to use. The recovering rate of the nickel reaches above 99 percent, and the adsorbed solution conforms to an industrial waste water discharge standard.
