Abstract:

The acidic wastewater generated by gold smelting enterprise is generally treated by the lime neutrali-zation method and returned to the system，but the disadvantage of this method is that the chloride ions in the wastewater can not be removed.In order to eliminate the harm caused by the continuous deposition of chloride ions，an experimental study was carried out on smelting acidic wastewater.Usually，the principle of chloride ion removal is to replace chloride ions with other anions or remove chloride ions together with other cations.Cuprous oxide was used as precipitant and precipitated with chloride ion，so that to achieve the purpose of removal.In the experiment，in order to determine the best experimental conditions，the chloride ion is investigated under different pH，temperature and cuprous oxide dosage.The removal effect is measured by the chloride removal rate.Finally，the good experimental results of chlorine removal rate above 95% can be obtained under the condition that the pH value of the solution is 0.5，the amount of cuprous oxide is 10 mg/L，and the reaction rate is 20 min at room temperature.The results show that the use of cuprous oxide can effectively remove the chloride ions in the acid smelting acid waste water，and the formed cuprous chloride precipitate is stable in acidic wastewater and easy to be filtered and removed.In the actual production process，cuprous oxide also can circulating dechlorination，which saves production cost and provides a data reference to remove chloride ions from acidic for the same type of companies.
