Method for treating stainless steel pickling waste liquor and recovering iron, chromium and nickel

The invention discloses a method for treating stainless steel pickling waste liquor and recovering iron, chromium and nickel. According to the method, a sodium hydroxide solution is adopted to control the pH of the stainless steel pickling waste liquor to achieve the purpose of recovery of iron, chromium and nickel through fractional precipitation. Because pH ranges of deposition of the iron, chromium and nickel elements are overlapped, part of iron oxide-hydroxide is precipitated firstly in a separation and recovery process, residual iron and chromium elements are co-precipitated out, and then chromium is precipitated and dissolved under the strong alkaline condition to realize final separation of iron and chromium. Due to presence of ammonia water and a reducing agent, the nickel element exists in the form of ions or a nickel ammine complex, is dissolved in the waste liquor, and finally reacts with a sulfide to precipitate NiS. The method has the characteristics of low cost, easiness in control, high separation and recovery rate of the iron, chromium and nickel elements and the like.
