摘　　要：采用Fenton氧化法深度处理食品添加剂经常规二级处理后的废水。研究了H2O2/CODcr投加量比、Fe2+/H2O2投加量比、反应pH和反应时间对废水CODcr去除效果的影响。结果表明,通过Fenton氧化,可使废水中CODcr由393.2mg/L降到64.3mg/L,去除率达83.6%;处理该废水的最适条件为:H2O2/CODcr=3,Fe2+/H2O2=1,pH4,反应时间60m in。The advanced wastewater treatment of food additives was studied by Fenton oxidation. The effects of H2O2/CODcr,Fe^2＋/H2O2, pH and reaction time on the removal of CODcr were studied. The results showed that CODcr could be reduced from 393.2mg/L to 64.3mg/L,the removal of CODcr was 83.6%, by Fenton oxidation. For this wastewater ,the optimum reaction condition were ： H2O2/CODcr = 3, Fe^2＋/H2O2 = 1, pH 4, reaction time 60min.
