| Abstract: | In this study,SO2-air oxidization method was used to treat cyanidation wastewater after extracting gold in a gold smelter in Henan.The influences of pH,reaction time,SO2 and air dosage amount on cyanide removal were investigated.For cyanidation wastewater with 55 mg/L of cyanide mass concentration,the cyanide mass concentration of treated water was 0.16 mg/L and the cyanide removal rate was higher than 99 %,which was lower than the national standard Grade Ⅲ for surface water emission.Good results were reached by using the new settlement agent to remove the heavy metals contained in the wastewater. |
| Keywords: | cyanidation wastewater heavy metal new settlement agent removal rate |
