摘　　要：针对新型的污酸处理工艺“深度硫化+吹脱+结晶法”存在投资大、能耗高、单位处理成本高的问题,提出一种铜渣协同脱氟氯工艺。经正交试验表明,在液固比8∶1、温度30℃、转速300 r/min、反应时间45 min,脱氯效果为96.44%;在脱氯污酸中,按氧化钙4 g/L、温度40℃、转速100 r/min、反应时间15 min,除氟效果为86.51%。New waste acid treatment process“deep vulcanization+air stripping+crystallization method”has the following problems,such as big investment,high energy consumption,high unit processing costs,so a kind of co-decorfluorochlorine process of copper slag was proposed,and the orthogonal test results show,when liquid-solid ratio is 8∶1,the temperature is 30℃,the rotating speed is 300 r/min,and the reaction time is 45 min,the dechlorination effect is 96.44%;and in the dechlorinated waste acid,when calcium oxide is 4 g/L,the temperature is 40℃,the rotating speed is 100 r/min,the reaction time is 15 min,therefore the dechlorination effect is 86.51%.
