| Abstract: | Wastewater containing nickel,chromium,zinc and copper ions was treated by ferrite process.The effects of pH and FeSO4 dosage on the removal efficiencies of heavy metals were studied.The optimal pH is 8.00-9.80 for nickel plating wastewater,8.00-10.50 for zinc plating wastewater,and 10.00 for copper plating wastewater.The optimal molar ratio of Fe2+ dosed to nickel,zinc or copper ions is 2-8.For chromium plating wastewater,the optimal pH is 4.00-5.50 for reduction of Cr(VI) to Cr(III) and 8.00-10.50 for flocculation of Cr(III),and the optimal molar ratio of Fe2+ dosed to Cr(III) is 20.The mass concentrations of nickel,chromium,zinc,and copper ion in the wastewater treated by ferrite process were <1.0 mg/L,<1.5 mg/L,<2.0 mg/L,and <0.5 mg/L respectively,reaching the national effluent discharge standard. |
