摘要
研究了用氧化亚铜脱除高氯废水中的氯,考察了氧化亚铜用量、反应温度和反应时间对氯脱除率的影响,并通过响应曲面法优化试验条件。结果表明:在氧化亚铜用量为n(Cu)/n(Cl)=1.3、反应温度70℃,反应时间2.0 h条件下,氯脱除率为95.37%;响应曲面法优化试验条件为氧化亚铜用量为n(Cu)/n(Cl)=1.35,反应时间2.26 h,反应温度79.8℃,该条件下的氯脱除率为97.61%,仅比预测值低0.08%,表明氯脱除率二阶模型预测结果可靠有效。用响应曲面法优化得到氧化亚铜处理高氯废水工艺条件合理可行。
The removal of chlorine from high chlorine wastewater using cuprous oxide was studied.The effects of cuprous oxide dosage,reaction temperature and reaction time on the chlorine removal rate were investigated.The test conditions were optimized by response surface method.The results show that under the conditions of cuprous oxide dosage of n(Cu)/n(Cl)=1.3,reaction temperature of 70℃and reaction time of 2.0 h,the chlorine removal rate is 95.37%.After optimization by response surface method,under the conditions of cuprous oxide dosage of n(Cu)/n(Cl)=1.35,reaction time of 2.26 h and reaction temperature of 79.8℃,the chlorine removal rate is 97.61%,which is 0.08%lower than the prediction results.This indicates that the prediction results of the second-order model of chlorine removal rate are reliable and effective,and the optimal technological conditions of cuprous oxide treatment of high chlorine wastewater by response surface method are reasonable and feasible.
