摘　　要：采用芬顿法对难降解的某涂料生产废水进行试验研究。结果显示,在n(H_(2)O_(2)):n(FeSO_(4))为1.4、n(H_(2)O_(2)):n(COD)比值为10.5的条件下,COD处理效果可达到93.92%;当固定n(H_(2)O_(2)):n(FeSO_(4))为1.2~1.4范围内,并按n(H_(2)O_(2)):n(COD)比值为3.1~10.5调整药剂投加量时,COD去除率由46.06%增至93.92%;然而,在分别固定n(H_(2)O_(2)):n(COD)比值为3.1、10.5的情况下,根据不同的n(H_(2)O_(2)):n(FeSO_(4))比值(1.2~2.8内)调整FeSO_(4)投加量并不能显著提升COD去除效果。此外,二级芬顿法也可有效去除COD,且所需的FeSO_(4)投加量显著低于一级。The Fenton method was employed to investigate the treatment of the refractory wastewater from a coating production.The results demonstrated that the COD removal efficiency of 93.92%was achieved when the ratio of n(H_(2)O_(2)):n(FeSO_(4))was 1.4 and the ratio of n(H_(2)O_(2)):n(COD)was 10.5.By maintaining a fixed n(H_(2)O_(2)):n(FeSO_(4))ratio between 1.2~1.4 and an added n(H_(2)O_(2)):n(COD)ratio between 3.1~10.5,the COD removal rate increased from 46.06%to 93.92%.However,adjusting the FeSO_(4)dosage according to the n(H_(2)O_(2)):n(FeSO_(4))ratio ranging from 1.2 to 2.8 had no significant impact on COD removal when using respective ratios of n(H_(2)O_(2)):n(COD)at 3.l and l0.5 respectively.Furthermore,employing a two-stage Fenton also improved COD removal efficiency with significantly lower FeSO_(4)requirements compared to the primary Fenton.
