研究了臭氧投加量为33、38和47 mg/l时，H2 O2存在下腐殖酸和富里酸的臭氧化反应。测定了这些化合物的化学需氧量（COD）和总有机物（TOC）。结果表明，在H2 O2存在下，臭氧氧化能有效地去除COD和TOC。在0.78mgO_3/mgCOT和0.088H_2O_2/O_3条件下，30 min内COD去除率为94%，TOC去除率为38%，1.35mgO_3/mgCOT和0.04H_2O_2/O_3条件下，30 min内COD去除率为88%，COT去除率为68%;在1.92 mgO 3/mgCOT和0.61 H2 O2/O3条件下，30 min内COD去除率可达79%，COT去除率可达75%。
Ozonation of humic and fulvic acids in aqueous solutions and in the presence of H2O2was studied at ozone doses of 33, 38 and 47 mg/l. Chemical oxygen demand (COD) and total organic compounds (TOC) of these compounds were tested. It was found that COD and TOC can be removed effectively by ozonation in the presence of H2O2. At 0.78 mg O3/mg COT and 0.088 H2O2/O3, about 94% COD and 38% TOC were eliminated in 30 min; at 1.35 mg O3/mgCOT and 0.04 H2O2/O3, about 88% COD and 68% COT were eliminated in 30 min; and at 1.92 mgO3/mgCOT and 0.61 H2O2/O3, about 79% COD and 75% COT were eliminated in 30 min.
