摘　　要：针对铜冶炼烟气制酸工艺中,使用固体Na_(2)S作为除砷药剂存在成本高、使用过程自动化程度低等缺点。现使用液体NaHS替代固体Na_(2)S作为除砷药剂处理废酸,对除砷效果、药剂成本和生产现场情况进行分析,结果表明:液体NaHS是高性价比的除砷药剂,有利于在废酸处理工序实现降本增效。In the copper smelting flue gas acid production process,the use of solid Na_(2)S as an arsenic removal agent has drawbacks such as high cost and low automation of the use process.Liquid NaHS is now used instead of solid Na_(2)S as an arsenic removal agent to treat waste acid.By analyzing the arsenic removal effect,agent cost,and production site conditions,it is concluded that liquid NaHS is a cost-effective arsenic removal agent,which can achieve cost reduction and efficiency increase in the waste acid treatment process.
