摘　　要：以实际阿特拉津含盐废水为处理对象,采用芬顿法对其进行预处理。通过正交试验和单因素试验研究了芬顿氧化体系中H_2O_2用量、H_2O_2和Fe^(2+)的比值、pH值、温度和反应时间对阿特拉津含盐废水COD去除率的影响。结果表明:在H_2O_2用量为4.44 mg/L,ρ(H_2O_2)/ρ(Fe2+)=20∶1,pH=5,温度为60℃,反应时间在120 min的条件下,阿特拉津实际废水COD的去除率可达90.5%。Based on the method of orthogonal and single factor experiment,the atrazine salinity wastewater was treated by Fenton oxidation. The dosage of H_2O_2,the ratio of H_2O_2 with Fe^（2＋）,pH and time were determined. The results showed that the optimal operation parameters were that： The dosage of H_2O_2,the ration of H_2O_2 with Fe^（2＋）,pH,temperature and react time was 4. 44 mg / L,20∶ 1,5,60 ℃,120 min,respectively. Under these conditions,COD removal efficiency of atrazine salinity wastewater could reach 90. 5%.
