| Abstract: | The combination technique of adjusting the pH by lime-scrap iron replacement-sulfide precipitation was utilized to treat the acidic copper-containing wastewater.The results showed that the recovery of sponge copper was 97.15 % when the pH of solution of scrap iron replacement was controlled at 2.After treatment of replacement of the solution by lime and sodium sulfide,the highest removal rate of copper was 99.24 % and the solution was obtained wastewater discharge standard. |
